Pulmonary adenoid cystic carcinoma (PACC) is an exceedingly rare tumor of low-grade malignancy. Diagnosis is often late, so the tumoral process may be huge at presentation. Surgical resection could be challenging, and the recurrence rate would be greater. We report, hereby, a case of proximal PACC with involvement of the carina in a young male adult, without respiratory distress. Surgical resection was performed through a left pneumonectomy followed by a complex trachea-bronchoplastic procedure. During the operative time, the assisted ventilatory mode was carefully chosen. No adjuvant treatment was needed. Our patient is still under clinicoradiological surveillance and remains disease-free.

Background Hydatidosis of the thoracic wall differs from other hydatid localizations in its pathophysiology, diagnostic, and therapeutic management. It is a little-studied entity. The objectives of our work were to describe its surgical management and to analyze the factors that may influence recurrence and mortality. Methods A retrospective, descriptive, longitudinal, and multicenter study on four university hospital surgical centers of Tunis, from January 1995 to December 2022 including operated hydatid cysts of the thoracic wall. Overall survival (OS) and cumulative recurrence rates were calculated. Univariate and multivariable Cox regression analyses were performed to identify recurrence and mortality risk factors. Results Forty-nine patients were included. The mean age was 41 ± 17 years [8-76]. The main presenting sign was thoracic parietal swelling (n=22). Chest ultrasound and CT scan showed multivesicular formation in 17 and 33 cases, respectively. Muscle involvement was in the intercostal (n=4), paravertebral (n=13), and pectoralis major (n=3) muscles. Bone involvement was vertebral (n=11), costal (n=12), costo-vertebral (n=21) and sternal (n=2). A posterolateral thoracotomy was performed (n=20). Surgical excision at various levels of the chest wall with spinal stabilization (n=15) was performed. Sixty-three percent of the patients received antiparasitic medical treatment. Recurrence occurred in 37% of cases. Four patients died from hydatidosis-related complications. Factors could be independently associated with recurrence such as male gender, and vertebral involvement. The presence of a visceral hydatid cyst located at a distance from the parietal lesion at the time of diagnosis and the occurrence of postoperative infectious complications could increase mortality. Conclusions Chest wall hydatidosis represents a rare medical condition where surgery remains the preferred treatment modality. However, it carries a substantial burden of morbidity and mortality, influenced by various factors. Further large-scale studies are necessary to gain a deeper understanding of these factors and to optimize management strategies accordingly.

Pulmonary hamartomas are the most common benign tumors of the lung in adults. They are usually asymptomatic because of their small size and their slow-growing character. We report the case of a 5-year-old child presenting with a giant lung mass causing recurrent right pneumonia. Surgical resection with middle lobectomy was performed. Final histology revealed pulmonary hamartoma with predominant adenofibromatous and lipomatous differentiation.

Abstract Background Fractures of the clavicle are common injuries, which often require reduction and internal fixation. Although Kirschner pins have been commonly used to treat these fractures with good results, migration of these devices may result in severe internal lesions. Case presentation We report herein the case of 61-year-old man, who presented for intrapulmonary migration of a Kirschner pin, 25 years after closed reduction and fixation of a clavicle fracture. Conclusion Migration of an osteosynthesis pin can be lethal. Patients with osteosynthesis pins, should have a regular follow, until the removal of the wires.

Introduction: The bronchogenic cyst is a congenital anomaly of the trachea and the bronchi resulting in a malformation that develop in the bronchial tree, most often in the middle mediastinum. It is a benign pathology, often asymptomatic, however in the case of a large bronchogenic cyst, signs of compression of the intra-thoracic organs appear and early surgery is necessary to avoid complications. Case presentation: A 49-year-old patient was referred to our department with dry cough, dyspnea and chest tightness progressing for six months. Radiological exploration concluded that a giant bronchogenic cyst, 90 mm in diameter, was very probable. Surgery was performed via a right posterolateral thoracotomy. Intraoperatively, there was a large cystic formation 100mm*80 mm of the middle mediastinum in intimate contact with the origin of the right pulmonary artery, the lower right pulmonary vein as well as the right atrium exerting a compressive effect on the bronchi. The lesion was firmly adhered to the pericardium. The cystic was ‘en bloc’ resected in totality. The postoperative course was uncomplicated. Histological examination confirmed diagnosis of a bronchogenic cyst. The patient was asymptomatic throughout the follow-up period. Clinical discussion: Apart from the possibility of malignant degeneration, a bronchogenic cyst can increase in size and become huge causing serious complications. Despite the predictive diagnostic value of imaging, definitive diagnosis of a bronchogenic cyst is confirmed by surgical excision and pathological examination. Conclusions: Surgery is almost obligatory especially if the cyst is above a certain size (about 60 mm) and in the case of giant bronchogenic cysts.
