A 28 year old female presented with the complaint of painful chest wall swelling on the left side anteriorolaterally,for the past three years. Her Trucut biopsy was inconclusive. Incisional biopsy proved it to be aneurysmalbone cyst. It was excised and chest wall was reconstructed with propylene mesh and muscle flaps. Her postoperativerecovery was smooth.

Extrapulmonary tuberculosis has increased in the last few decades, and establishing a diagnosis is still challenging. A 15 years old Indonesian adolescent complained of a lump on the right lung. The patient and his mother had a history of pulmonary tuberculosis and received the anti-tuberculosis drug. Chest inspection showed a soft consistency mass, smooth surface, poorly defined borders, and size of 7 × 7 cm in the posterolateral dextra region. Radiological examination showed a mass of 2 × 2.5 × 5.3 cm in the right anterior mediastinum. FNAB lymph nodes showed granulomatous inflammation consistent with tuberculosis. The patient had a wide excision tumor, and a GeneXpert MTB/RIF examination of the tumor excision material showed that Mycobacterium tuberculosis was detected very low. The patient received an anti-tuberculosis drug and had a good prognosis. Patients with a family history of tuberculosis should be examined for tuberculosis. Although in a patient with lung carcinoma signs and symptoms, it does not rule out chest wall tuberculosis. Enforcement of the correct diagnosis can increase the prognosis of extrapulmonary tuberculosis. • GeneXpert MTB/RIF examination should be performed on patients with a family history of tuberculosis. • Management of Chest wall tuberculosis included incision and anti-tuberculosis drugs. • Extrapulmonary tuberculosis does not have non-specific signs and symptoms.

Chest wall tumor usually requires enbloc resection of tumor with overlying skin, adjoining ribs, and occasionally sternum. An ideal prosthetic material to cover the bony defect as well as maintain respiratory mechanics is yet to be developed. Commonly available methods include combination of the mesh with rigid metallic plates, bone cement, etc., over the skeletal defect, which is then covered with a muscle flap. Here, we are reporting a case of Chondrosarcoma Rib in which rib was reconstructed using non-rigid stainless steel wire, which is easily available and simple to perform. [ABSTRACT FROM AUTHOR]

We report a case of a 17-year-old male with a giant cell tumor originating from the rib and presenting as an intra-thoracic mass. It is a benign, locally aggressive neoplasm seen infrequently. Thoracotomy and en bloc resection of the mass were carried out successfully. [ABSTRACT FROM AUTHOR]

Introduction Myofibromas are benign mesenchymal neoplasms that can present as solitary and multicentric lesions. They can occur in several locations and can occur at any age from neonates to elderly patients. However, most of the lesions are found in neonates and babies. It rarely occurs in adults. Case presentation A 29-year-old Taiwanese man presented with persistent dull chest pain in his right lateral chest wall for 2 weeks. A chest X-ray showed a faint patchy opacity over the periphery of his right upper lung zone. Computed tomography and magnetic resonance imaging showed a lobulated mass at the intercostal space between his right fifth and sixth ribs with contrast enhancement and bone invasion. Malignancy could not be excluded. A percutaneous needle aspiration biopsy failed due to technique issues, so he underwent a thoracotomy and the tumor was excised with Marlex mesh repairs for the thoracic defect. Pathology confirmed a myofibroma without malignancy. He recovered uneventfully and no local recurrence was detected at the 1-year follow-up examination. Conclusions Chest wall myofibroma presenting with chest pain has never been reported in adults. It is a challenge to differentiate myofibroma from malignancy in chest wall preoperatively, such as seen in our patient. To the best of our knowledge, this has not been previously reported in the scientific literature. Although myofibroma rarely occurs in the chest wall and adults, it must be suspected in any chest wall tumor presenting with chest pain. [ABSTRACT FROM AUTHOR]

Tumors of the bony thorax are rare and present unique challenges in achieving optimal oncologic results. Negative margins can be quite difficult to obtain because of the proximity to vital structures, hence rendering wide resection challenging. Chest wall resections are also complex because of the necessity for restoration of a functional chest wall with adequate soft tissue coverage to prevent paradoxical respiration and to mitigate pulmonary complications. Traditionally, thoracic surgeons have treated chest wall tumors. However, at some centers, orthopaedic oncologists have performed resections and reconstructions of these tumors with minimal perioperative morbidity. Previous studies have shown both an increase in the number of wide resections and a survival benefit for the treatment of these tumors when care is provided at a sarcoma center of excellence with a multidisciplinary team. We recommend a multidisciplinary treatment algorithm for these tumors with a musculoskeletal oncologist, thoracic surgeon, and plastic surgeon to bring about successful wide resection of the tumor, restoration of functional chest wall kinetics, and appropriate soft tissue coverage.

Background A malignant fibrous histiocytoma (MFH) rarely originates from the chest wall. Clinical findings In this case, we describe a 59-year-old Chinese woman who presented with an enormous mass originating from the left chest wall and involving the left upper pulmonary lobe. Therapy After a radical en-block resection of the entire chest mass with left upper pulmonary lobectomy, and the chest wall reconstruction, a histopathologic diagnosis of the giant cell MFH was rendered. She has done well postoperatively, showing no local recurrence or distal disease in an 8-month follow-up period. Conclusion Although a MFH originating from the chest wall is rare, it should be considered in the differential diagnosis of a chest wall tumor.

Primary chest wall tumors occur infrequently; in particular, cavernous hemangioma of the chest wall is an extremely rare disease. We report a case of child with cavernous hemangioma of the chest wall, which was successfully resected. Obvious enlargement of the tumor and the appearance of pain were observed during a 2-year follow-up. In the present case, transcutaneous ultrasonography showed the appearance and disappearance of the mass. This was considered to be caused by the transfer of contents between the shallow and deep parts of the tumor. This may have resulted from serratus anterior muscle movement between the two-layered tumor. Transcutaneous ultrasonography, as well as magnetic resonance imaging, was therefore extremely effective for preoperative diagnosis. Transcutaneous ultrasonography is easily performed, even in children, such as in the present case. Because of its simplicity and usefulness, transcutaneous ultrasonography may be considered as the first-line imaging modality for diagnosis. [ABSTRACT FROM AUTHOR]

Background: An elastofibroma is a benign, soft-tissue tumor and is important in the differential diagnosis of thoracic wall masses. Here, patients with elastofibromas who underwent thoracic surgery were retrospectively reviewed to elucidate elastofibroma formation and to facilitate the differential diagnosis. Methods: This is a retrospective and descriptive study of a series of 30 patients with elastofibroma dorsi. The data was obtained by review of the hospital records. Results: There were 27 female and three male patients (mean age, 55.13 ± 8.7 years) with a total of 42 elastofibroma dorsi tumors (12 bilateral cases, 18 unilateral cases) diagnosed between January 2004 and October 2011. Twenty patients (67%) underwent surgery as a result of subscapular swelling and pain. In 10 (33%) asymptomatic patients, elastofibromas were found incidentally during a thoracotomy. Imaging methods in symptomatic patients included computerized tomography (15 cases), magnetic resonance (three), and ultrasonography (two). For five patients, fluorodeoxyglucose uptake values were available and revealed mild metabolic activity in the elastofibromas. Elastofibromas were significantly larger in symptomatic patients (8.15 ± 1.9 vs. 6.2 ± 2.3; P= 0.02). Exposure to long-term repetitive micro-trauma was a precipitating factor in 23 (77%) patients. Seroma formation, the most common surgical complication, was observed in 40% of patients. Conclusion: The differential diagnosis of elastofibroma dorsi is straightforward, and preoperative histology is unnecessary when the clinical, radiological, and metabolic characteristics are known. Repetitive micro-trauma may predispose to hyperproliferation of fibroelastic tissue, and genetics may also play a role. Surgical treatment can be reserved for cases with severe symptoms.

Chest wall tumor resection can result in a large defect that can pose a challenge in reconstruction in restoring chest wall contour, maintaining respiratory mechanics, and improving cosmesis. Titanium plates were first introduced for treating a traumatic flail chest, which yielded promising results in restoring chest wall stability. Subsequently, the applications of titanium plates in chest wall reconstruction surgery were demonstrated in case reports and series. Our center has adopted this technique for a decade, and patients are actively followed up after operation. Here, we retrospectively analyze our 10-year experience of using titanium plates and other reconstruction approaches for chest wall reconstruction, in terms of clinical outcomes, complications, and reasons for reoperation to determine long-term safety and efficacy. Thirty-eight patients who underwent chest wall resection and reconstruction surgery were identified. Of these, 11 had titanium plate insertion, 11 had patch repair or flap reconstruction, and the remaining 16 had primary closure of defects. Chest wall reconstruction using titanium plate(s) and patch repair (with or without flap reconstruction) was associated with larger chest wall defects and more sternal resections than primary closure. Subgroup analysis also showed that reconstruction by the titanium plate technique was associated with larger chest wall defects than patch repair or flap reconstruction [286.80 cm 2 vs. 140.91 cm 2 ( p  = 0.083)]. There was no 30-day hospital mortality. Post-operative arrhythmia was more commonly seen following chest wall reconstruction compared with primary closure ( p  = 0.041). Furthermore, more wound infections were detected following the use of titanium plate reconstruction compared with the patch repair (with or without flap reconstruction) approach ( p  = 0.027). In conclusion, the titanium plate system is a safe, effective, and robust approach for chest wall reconstruction surgery, especially in tackling larger defect sizes., Competing Interests: CN is a consultant for Johnson and Johnson; Medtronic, USA; and Siemens Healthineer.

Juvenile xanthogranuloma (JXG) is essentially a benign neoplasm arising from any site on the body; however, there has so far been only one report of JXG located on the chest wall involving a rib. This report presents a rare case finally diagnosed as JXG based on histopathological and immunohistochemical examinations. [ABSTRACT FROM AUTHOR]

OBJECTIVES The reconstruction of large full thickness chest wall defect after resection of T3/T4 non-small cell lung cancer (NSCLC) or primary chest wall tumours presents a technical challenge for thoracic surgeons and is a critical factor in determining post-operative outcome. When the defect is large, complications are common with a 27% mean rate of respiratory morbidity. METHODS Since 2006, 31 patients underwent reconstruction for wide chest wall defects using titanium implants and strong mesh. The reconstruction was achieved using a layer of polytetrafluoroethylene or a XCM biologic tissue mesh shaped to match the defect and sutured under maximum tension to re-establish the skeletal continuity. The mesh was placed close to the lung and was fixed onto the bony framework and onto the titanium plate. In one case, we used XCM biologic tissue because of a large infected T3 NSCLC. A horizontal titanium rib osteosynthesis system was used to reestablish the rigidity of the thoracic wall by bridging the defect except for one case in which we use a vertical rib osteosynthesis system. RESULTS Twenty-six patients underwent a complete R0 resection with the removal of a mean of 4.67 ± 1.5 [3–9] ribs, including the sternum in 14 cases. The mean defect area was 198 ± 91.2 [95–400] cm². Reconstruction required a mean of 2.06 ± 1.1 [1–4] titanium plates. There were two cases of deep wound infection that required surgical removal of the osteosynthesis system in one patient. Only one patient developed a major complication in the form of respiratory failure. There were two postoperative deaths neither of which was directly related to the surgical procedure. CONCLUSIONS Our experience and initial results show that titanium rib osteosynthesis in combination with strong biologic or synthetic mesh can easily and safely be used in a one-stage procedure for the reconstruction of major chest wall defects.

The elastofibroma Dorsis (EF) is a tumor that occurs most frequently in the chest wall's infrascapular region, have mild symptoms to pain, discomfort and loss of function.While it is a benign tumor that requires surgery for their symptoms and when it is necessary to differentiate malignant tumors. Objective: To analyse chest wall's tumors treated surgically and its complications. Method: were treated 13 patients with chest wall infrascapular tumors in whom resected 17 tumors. Results: 12 tumors were reported as EF, there was no presence of atypical cells in the treated tumors seroma formation was the most frequent complication. Conclusion: despite being a benign tumor EF requiring surgical treatment for their symptoms and frequency. [ABSTRACT FROM AUTHOR]

The clinical presentation of thoracic mesenchymal hamartomas varies from an asymptomatic chest wall mass to severe respiratory distress resulting from compression of the airways and lungs. We present the findings on fetal US and MRI of a histologically confirmed case. Following surgical resection, pathological examination corresponded to the cross-sectional imaging features with haemorrhagic, cystic and calcified components. An awareness of the characteristic imaging findings will allow accurate diagnosis of this condition, even prenatally, and thus facilitate appropriate perinatal management and surgical planning.

Abstract: Purpose: We have previously reported the use of the vertical expandable prosthetic titanium rib (VEPTR) for treatment of thoracic dystrophy. This report describes our experience with this device and other novel titanium constructs for chest wall reconstruction. Methods: This is a retrospective chart review of all children and adolescents undergoing chest wall reconstruction with titanium constructs between December 2005 and May 2010. Results: Six patients have undergone chest wall reconstruction with VEPTR or other titanium constructs. Four had chest wall resection for primary malignancy, 1 had metastatic chest wall tumor resection, and 1 had congenital chest wall deformity. There were no immediate complications, and all patients have exhibited excellent respiratory function with no scoliosis. Conclusions: Chest wall reconstruction after tumor resection or for primary chest wall deformities can be effectively accomplished with VEPTR and other customized titanium constructs. Goals should be durable protection of intrathoracic organs and preservation of thoracic volume and function throughout growth. Careful preoperative evaluation and patient-specific planning are important aspects of successful reconstruction. [Copyright &y& Elsevier]

Chest wall tumors are a heterogeneous group of lesions that provide an interesting diagnostic and therapeutic challenge for surgeons. They make up less than 5% of thoracic malignancies and vary widely in pathology as they arise from all anatomic structures of the chest wall. In general, treatment is wide local excision, the margins for malignant disease are necessarily wider, and adjuvant radiation is typically given for those with positive margins. Chemotherapy is rarely effective. Local control is the most important prognostic factor. Disease-free survival for malignant disease is limited by positive margins; therefore full oncologic resection with 4-cm margins should be attempted. For small lesions, the resection and reconstruction is usually straightforward. For more advanced disease or those lesions that require significant functional loss, preoperative planning using a multidisciplinary approach, incorporating thoracic surgery, plastic surgery, neurosurgery, radiation medicine, oncology, and physical medicine and rehabilitation, may be essential.

Solitary osteochondroma of the rib is a rare primary chest wall tumor. Herein, we report a case of a successfully resected osteochondroma of the rib. The patient was a 73-year-old asymptomatic woman who came to our hospital regularly for treatment of hypertension and hyperlipidemia. A checkup chest roentgenogram showed a shadow at the right anterior chest wall consistent with a mass, and computed tomography showed a tumor arising from the right fourth rib. Because it was impossible to exclude completely the diagnosis of a well-differentiated chondrosarcoma, we performed resection of the right anterior chest wall and a re construction with a rigid prosthesis. The post operative course of the patient was unremarkable. The final pathological diagnosis of the rib tumor was osteochondroma. [ABSTRACT FROM AUTHOR]

Introduction Soft tissue sarcomas of the chest wall are exceptionally rare entities that present as painless slow growing masses. Resection is often precarious due to involvement of vital structures, and patients are left with large chest wall defects postoperatively requiring extensive reconstruction. Presentation of case We present a case report of a 29 year-old man who presented with a giant soft tissue sarcoma of the chest that had been growing slowly for one year prior to presentation. The patient had a biopsy that was positive for sarcoma, and PET CT demonstrated a large lobulated mass in the left chest wall with an SUV of 6.7. He received 50 Gy of radiation therapy; however, the mass continued to grow in size. He subsequently underwent an en-bloc resection of the mass with latissimus and serratus muscle primary reconstruction. Final pathology showed a 27 cm high-grade fibrosarcoma with prominent myxoid component. To our knowledge, this is the largest soft tissue sarcoma of the chest wall reported in the literature. Postoperatively, the patient received 6 cycles of adjuvant chemotherapy. Discussion Surgery is the mainstay of treatment, and chemotherapy and radiation are used in specific circumstances. Risk of recurrence is dependent on many factors, including histologic subtype, grade, and size of tumor. Long term surveillance with physical exam and imaging is recommended. Conclusion We feel that the multidisciplinary approach is crucial for optimal management of large soft tissue sarcomas. We recommend this approach to all patients with chest wall sarcomas.

Malignant triton tumor is a rare malignant peripheral nerve sheath tumor with rhabdomyoblastic differentiation. Most of these tumors are located in the head, neck, and extremities, and about half of cases are associated with neurofibromatosis type 1 featuring cafe-au-lait spots or cutaneous neurofibromas. We present a 76-year-old man with an insidious chest wall tumor with late progressive painful enlargement and pleural and pulmonary involvement. Complete resection of the affected thoracic wall as well as single separate lesions in the parietal pleura and left upper lung was carried out. The pathological examination confirmed that it was a malignant triton tumor. The patient received adjuvant chemoradiotherapy but eventually succumbed to disease relapse and distant metastases 6 months after the surgery. [ABSTRACT FROM AUTHOR]

Objective: To compare the clinical curative effect of fascia repair with dacron cloth repair resection of chest wall defect of chest wall tumor. Methods: 81 chest wall tumor patients fromdepartment of thoracic surgery in our hospital were selected and randomly divided into the Tensor fascia group (40 cases) and the Polyester fabric group (41 cases). The analgesic dosage, pulmonary signs, lead flow, CRP, white blood cell and clinical rehabilitation were compared between two groups. Compared with the tensor fascia group, the analgesic effect, respiratory confinement time and incidence rate of pleural adhesion were lower(P<0.05). Compared with before treatment, the white blood cell level were higher(P<0.05),the C reactive protein level were lower(P<0.05). Results: Compared with the tensor fascia group, the level of white blood cell, the days to restore normal SPO2 level after the treatment of polyester fabric was shortened (P<0.05), the postoperative fever days, drainage days and length of stay in hospital were shorter(P<0.05). Conclusions: The clinical curative effect of polyester fabric repair is superior to the traditional tensor fascia repair with less pain and fast recovery, worthy to be popularized.

The authors describe a case of a 36-year-old patient who had six months' pain of the thoracic spine and left chest. A soft slowly growing resistance was present on the dorso-lateral side of the left chest wall, in the range of the seventh to ninth rib. According to the medical history, the patient did not have any prior trauma and malignancy. A well-defined tumor of the left chest wall with calcifications, which grew to the seventh and eighth intercostal space, was present on computed tomography (CT) and magnetic resonance (MR) scans. The patient underwent resection of the tumor with the chest wall and reconstruction with polypropylene mesh. Histologically, it was a venous hemangioma, one of very rare tumors of the chest wall.

Thoracic neurogenic tumors typically originate from the posterior mediastinum and the intercostal nerves. No report of a chest wall schwannoma extending toward the subphrenic areas and making a significant indentation into liver parenchyma exists to date. We present a liver tumor-mimicking schwannoma of the intercostal nerves. A 58-year-old woman presented with a painful lesion in the right subphrenic area and abdominal pain in the right upper quadrant for two months. Abdominal ultrasonography and magnetic resonance imaging revealed a tumor, 9.1 � 7.1 � 8.9 cm in size, with an inner cystic change in segment V and VI of the liver. The tumor was completely resected together with part of the 9th rib. Pathology confirmed a schwannoma and showed a tumor composed of spindle cells with oval to wavy nuclei. The patient was still asymptomatic at follow-up after 36 months, with no sign of recurrence. [ABSTRACT FROM AUTHOR]

The purpose of our retrospective article is to review the CT imaging features of chondrosarcomas of the chest wall with pathologic correlation. For 26 subjects with biopsy-proven chondrosarcomas of the chest wall, two musculoskeletal radiologists retrospectively reviewed 26 CT scans in consensus. Descriptive statistics were performed. The mean tumor size was 57 mm. Twenty (20/26, 77%) chondrosarcomas were located in the ribs and six (6/26, 23%) in the sternum. The majority were lytic (19/26, 73%) with <25% calcification (15/26, 58%), and with a soft tissue mass (22/27, 85%). In this study CT features of grade 1 chondrosarcoma overlapped with those of grade 2 tumors. In conclusion, chondrosarcomas of the chest wall are generally lytic with an associated soft tissue mass, showing little calcified matrix and low-to-intermediate grade. [ABSTRACT FROM AUTHOR]

Actinomycosis is a rare disease in children and young adolescents and its thoracic manifestations accounted for a minority of all cases. We report a case of a 12-year-old boy who presented with a right anterior chest wall mass for one week together with weight loss and low grade fever for one month. His symptoms and signs as well as the results of the radiological investigations (i.e. chest X-ray and computed tomography (CT) of thorax with contrast) mimicked pulmonary tuberculosis or chest wall tumor. The definite diagnosis of actinomycosis relies on the Gram stain microscopy and culture of the chest wall lesion aspirates. An early and accurate diagnosis can prevent the patient from unnecessary invasive procedures such as open lung biopsy or thoracotomy. The mainstay of the treatment of actinomycosis remains to be a combination of abscess drainage as well as prolonged antibiotics such as penicillin. Follow-up CT scan of thorax with contrast is useful in monitoring the progress of disease recovery. [ABSTRACT FROM AUTHOR]

Chest wall tumors (CWT) are rarely seen in childhood and surgery constitutes a complementary part of the therapy. The early and late results of CWT resection and chest wall reconstruction were evaluated retrospectively. The children who underwent chest wall resection for CWT between January 1990 and November 2003 were evaluated retrospectively. Seventeen children (male/female = 12/5, mean age: 7.58 years) underwent chest wall resection for CWT. Fifteen patients underwent initial biopsy (tru-cut, n = 8 or open biopsy, n = 7) and two underwent initial resection. The diagnosis was malignant tumor in 12 (70%) and benign in 5 (30%). They were Ewing's sarcoma (ES) (n = 4), primitive neuroectodermal tumor (PNET) (n = 3), Askin's tumor (n = 1), rhabdomyosarcoma (RMS) (n = 2), neuroblastoma (n = 2), osteochondroma (n = 1), aneurysmal bone cyst (n = 2) and hamartoma (n = 2). Preoperative chemotherapy was given to most patients with malignant tumor. All patients had only local tumor at the time of resection. Thoracotomy was performed in all patients. All tumor tissues with the affected rib/ribs were resected en bloc with the adjacent tissues. The number of resected ribs was 1 (n = 6), 2 (n = 7) and 3 (n = 4). Chest wall defects were repaired primarily (n = 8) or with grafts (n = 9). Dura (n = 4), Neuro-patch (n = 3) and Goretex (n = 2) were used for closure. Wound infection and pleural fistula occurred in one patient. Patients with benign tumor were free of complaints or complications during follow up. All patients with malignant tumor received postoperative chemotherapy. Local recurrence did not occur in all patients. Five patients developed distant metastasis and two died. Scoliosis was encountered in one patient during follow-up. Since most of the CWT are malignant and not initially suitable for surgical excision, the management includes tissue diagnosis either by tru-cut or open biopsy. Determination of malignant condition should be followed by an intensive chemotherapy. Chest wall resection is planned to control local disease. Chest wall reconstruction may be needed for large defects following resection of CWT. Prosthetic materials can be used safely. Early complications of the surgery are limited. The patients should be closely followed up for late complications such as scoliosis, restrictive pulmonary disease and for the development of metastasis, which is a part of natural course of malignant CWT in children.

This paper presents a case of intercostal hemangioma, in which a complete surgical resection was accomplished based upon a tentative diagnosis provided by magnetic resonance imaging (MRI). A 27-year-old man visited our hospital for the evaluation of chest pain and shortness of breath after exertion. Computed tomography showed a soft tissue mass, 5.5×3.5 cm in size, arising from the right lateral 7th intercostal space. Dynamic MRI showed that the mass was enhanced rapidly in the early phase and that this early enhancement was maintained during the delayed phase, which was compatible with a diagnosis of intercostal hemangioma. The patient underwent surgery, and a complete resection of the tumor with the right 7th and 8th ribs and their intercostal muscles was accomplished. Histopathological examination confirmed the diagnosis of intramuscular hemangioma of the large-vessel type. Presently, 6 months after the operation, the patient is doing well, without any evidence of local recurrence. [ABSTRACT FROM AUTHOR]

Chondrosarcoma of a rib is a very rare malignant tumor of the bone. Most patients were present with an enlarging painful anterior chest wall tumor. We present a case of an asymptomatic 29-years old female with a tumor size of 10 cm × 12 cm on the left anterior chest wall involving the 8th rib. CT scan with intravenous contrast is the gold standard for radiological imaging and planning for surgery. Since chondrosarcoma is less sensitive to chemotherapy and radiotherapy, surgical treatment with extensive resection with a sufficient margin is considered first line treatment.

Objectives: The aim of the study is to evaluate clinical applications, safety, and effectiveness of a porcine-derived acellular cross-linked dermal matrix biological mesh in chest wall reconstruction., Methods: We retrospectively analyzed a prospective multicenter database of chest wall reconstructions using a biological mesh in adult patients undergoing operation between October 2013 and December 2020. We evaluated preoperative data, type of resection and reconstruction, hospitalization, 30-day morbidity and mortality, and overall survival., Results: A total of 105 patients (36 women [34.2%]; mean age, 57.0 ± 16.1 years; range, 18-90 years) were included, they have admitted for: primary chest wall tumor (n = 52; 49.5%), secondary chest wall tumor (n = 29; 27.6%), lung hernia (n = 12; 11.4%), trauma (n = 10; 9.6%), and infections (n = 2; 1.9%). The surgical sites were preoperatively defined as at high risk of infection in 28 patients (26.7%) or as infected in 16 (15.2%) patients. Thirty-days morbidity was 30.5% (n = 32 patients); 14 patients (13.3%) had postoperative complications directly related to chest wall surgical resection and/or reconstruction. We experienced no 30-day mortality; 1-year and 2-year mortality was 8.4% and 16.8%, respectively., Conclusions: Biological mesh represents a valuable option in chest wall reconstruction even when surgical sites are infected or at high-risk of infections. This mesh shows low early and late postoperative complication rates and excellent long-term stability., (© 2022 The Author(s).)

Mesenchymal chondrosarcoma is a rare malignant cartilaginous tumor arising within the bone or soft tissue. An 18-year-old woman presented with a tumor on her left fourth rib. We performed a wide resection of the tumor and administered three cycles of postoperative adjuvant chemotherapy. Three years after the operation, the patient is alive without any evidence of either local recurrence or distant metastases. The findings of this case may thus support the usefulness of a radical resection and adjuvant chemotherapy for mesenchymal chondrosarcoma. [ABSTRACT FROM AUTHOR]
