BACKGROUND Extramammary Paget's disease (EMPD) is a rare neoplasm that commonly affects post-menopausal women. It usually presents in the anogenital area where apocrine sweat glands are abundant, most commonly in the vulva. The disease is characterised by slow growth and high local recurrence rates. Clinically, EMPD presents as well-demarcated erythematous lesions or plaques that may be ulcerated. Microscopically, it shows a group of atypical cells with abundant clear cytoplasm and nuclear pleomorphism. METHODS We present the case of a 58-year-old female with a history of poorly differentiated squamous cell carcinoma of the cervix, status post-radical-hysterectomy with bilateral salpingo-oophorectomy, and chemoradiation in 2016. The patient also had a long-standing history of vulvar pain, skin changes on her left labia, and itching. RESULTS Punch biopsies of the vulva revealed acanthosis and acantholysis of the epidermis with an intraepidermal scattering of single, or clusters of, large cells with round/oval nuclei and abundant clear cytoplasm. The cells were positive for p16, CK19, CK7, and PAX8, supporting the diagnosis of EMPD without evidence of dysplasia. The concurrent Papanicolaou smear showed a hypercellular specimen composed of hyperchromatic tissue fragments with high nuclear-to-cytoplasmic ratios and apoptotic bodies. The presence of intracytoplasmic mucin and the tridimensionality of the fragments supported the diagnosis of adenocarcinoma. CONCLUSIONS This study compares the histological and cytomorphological features of EMPD with high-grade squamous intraepithelial lesions, since the pathogenesis, precursor lesions, etiological associations, staging, clinical treatment, and prognosis differ substantially and may have a significant clinical impact on the patient's treatment.

Myelodysplastic/myeloproliferative neoplasm with ring sideroblasts and thrombocytosis (MDS/MPN with RS-T), which exhibits both an increased number of marrow ring sideroblasts and thrombocytosis, is a rare disorder classified as one of the newly established forms of MDS/MPN in the WHO 2016 classification. Systemic mastocytosis (SM) is a heterogeneous group of neoplasms characterized by growth and accumulation of both cytologically and immunophenotypically abnormal mast cells in one or more body organ systems. SM can occur as a separate neoplasm but commonly is associated with other clonally related myeloid neoplasms. Herein, we present a 78-year-old female with a clinical history of fatigue, dyspnea, and a compression fracture of L5. Her peripheral blood, bone marrow aspirate, and biopsy laboratory workup show features of myelodysplasia with ring sideroblasts, thrombocytosis, and clusters of mast cells in the bone marrow biopsy. Pathogenic c-KIT, MPL, and SF3B1 genes are identified by the molecular study. We present this case to point out a rare combination of systemic mastocytosis and MDS/MPN with ring sideroblasts and thrombocytosis. It is not known if the best treatment should be focused on the systemic mastocytosis or the accompanying MDS/MPN.

Classic Hodgkin lymphoma (CHL) is a clonal lymphoid neoplasm derived from B cells. CHL usually involves the lymph nodes. Although cases with extranodal involvement by CHL have been reported, the involvement of the uterine cervix by CHL is an extremely uncommon phenomenon. Herein, we report an unusual case of a 51-year-old female with nodular sclerosis CHL, diagnosed initially via right inguinal lymph node biopsy. After two cycles of chemotherapy, she presented with vaginal spotting and CT scan demonstrated a uterine cervical lesion with hypermetabolic activity. Tissue biopsy sections of the uterine cervix showed cellular infiltrate consisting of large atypical cells including many lacunar cells and occasional Reed-Sternberg cells in the background of mixed reactive cells including small- to medium-sized lymphocytes, histiocytes, plasma cells, eosinophils, and neutrophils. Immunohistochemical stains show that the large atypical cells are positive for CD30, CD15, MUM-1, and weakly positive for PAX-5. In situ hybridization for Epstein-Barr virus-encoded RNA (EBER) is negative. The morphological and immunohistochemical findings were consistent with involvement by nodular sclerosis CHL. This case demonstrates a rare presentation of CHL that may pose a diagnostic problem if its existence is not considered in the differential diagnosis. Furthermore, we reviewed the literature and only found two previous publications described uterine cervix involvement by CHL. Although it is very rare, CHL involvement should be included in the differential diagnosis and an appropriate work-up should be performed to evaluate CHL involvement of cervix when patients with CHL present with signs or symptoms suggesting a cervical lesion.

Hypersensitivity pneumonitis (HSP) is an interstitial lung disease caused by exposure to a large range of environmental antigens. Inhaling aerosolized particles leads to a heightened immune response. HSP comes in acute, subacute, or chronic forms, all with their own potential clinical and radiographic findings. Mycobacterium avium complex (MAC) is the most common nontuberculous mycobacteria and is known to cause HSP with certain exposures. However, although certain histologic findings can be seen with HSP, a high ki-67 proliferation index is unusual and more commonly associated with malignancy. In this report, we discuss a case of MAC that had acute HSP associated with a high ki-67 proliferative index.

Currently, there is a worldwide obesity pandemic with an incidence that has increased progressively over the last few decades. Obesity is considered a global health hazard and is associated with a significant economic impact on the healthcare system. It has been linked to several serious medical conditions, including heart disease, hypertension, stroke, diabetes mellitus, and cancer. Obesity is also related to social and psychological problems such as anxiety and depression. Several factors predispose the population to obesity, including decreased physical activity and non-healthy dietary habits. Sugar is the most important key contributor to the pandemic of obesity, and implementing a sugar-free workplace policy will provide a promising strategy for fighting obesity.

Giant basal cell carcinoma (GBCC) is a rare skin cancer characterized by an aggressive biological behavior with extensive local invasion, frequent metastasis, and associated poor prognosis. Wide local excision with sentinel lymph node biopsy is often warranted for this condition, and reconstruction by local rotational flap is one of the best surgical techniques for repairing similar skin cancers with a relatively large skin defect. A 59-year-old man who was a former construction worker with a significant smoking history presented with a single giant suspicious chronic ulcerating skin lesion measuring 9 x 7 cm that proved to be a basal cell carcinoma (BCC) on his left shoulder. The patient was negative for enlarged or palpable lymph nodes and underwent a wide local excision and primary repair with a local flap. Despite negative margins, his follow-up visits at six, nine, and 10 months revealed numerous suspicious lesions that further required multiple local wide excisions that showed new basal cell carcinoma and recurrence to the left axilla. Given the invasiveness of his skin cancer, he was referred to oncology and later treated by chemoradiation. Patients with multiple risk factors are associated with a higher incidence of more invasive skin cancer due to possible cumulative effects. The therapeutic approach for GBCC should involve multidisciplinary teams, with wide local resection of the tumor with possible sentinel lymph node biopsy, local rotational flap for reconstruction of the wide defect, and adjuvant chemoradiotherapy if necessary.

Duodenal diverticulum (DD) is a common incidental finding, which rarely causes complications. Perforation is one of the most feared and the least common complications. Surgery is the mainstay for complicated duodenal diverticulum, but with the advancement of medical treatment and intensive care, nonoperative management has been reported. We present a rare case of perforated DD that failed medical management and subsequently underwent surgical intervention. A 77-year-old, healthy female presented with right-sided abdominal pain with low-grade fever and leukocytosis. Computed tomography (CT) of the abdomen showed retroperitoneal fluid collection around the second part of the duodenum, which was not amenable to percutaneous drainage. Contrast studies showed no evidence of perforation or leak of the stomach or duodenum. The diagnosis was made via an upper endoscopy that showed a large periampullary duodenal diverticulum with purulent drainage and normal-looking ampulla. After failed conservative management with broad-spectrum antibiotics and worsening symptoms, she underwent excision and primary repair of the diverticulum with a jejunal serosal patch and exploration of the common bile duct (CBD). She had an uncomplicated postoperative course and was discharged home on postoperative day four. Although rare, the duodenal diverticular perforation can be a life-threatening complication. Combined subjective, clinical, and radiological assessment of the patient is crucial in deciding whether to operate or not.

Introduction At Hiwa Cancer Hospital (Sulaymaniyah, Iraqi Kurdistan) after the center was started by a cooperative project in June 2016, autologous transplantation was developed. Patients and Methods To develop the project, the capacity-building approach was adopted, with on-site training and coaching of personnel, educational meetings, lectures, on-the-job training, and the implementation of quality management planning. Results Here, we report initial results of peripheral-blood stem-cell mobilization and collection of the first 27 patients (age 12 to 61 years; 19 males and 8 females; multiple myeloma, n = 10; plasma cell leukemia, n = 1; Hodgkin lymphoma, n = 12; non-Hodgkin lymphoma, n = 3; and acute myeloid leukemia, n = 1). Only three (11.5%) of 26 patients experienced a failure of mobilization. A median of 6.1 × 106/kg CD34-positive cells per patient were collected (range, 2.4 to 20.8), with two apheretic runs. Twenty-four patients underwent autologous transplantation. All but one transplantation engrafted fully and steadily, with 0.5 and 1.0 × 109/L polymorphonucleates on day 10.5 (range, 8 to 12) and day 11 (range, 9 to 15), respectively, and with 20 and 50 × 109/L platelets on day 13 (range, 10 to 17) and day 17 (range, 2 to 44), respectively. More than 95% of patients are projected to survive 1 year after autograft. Conclusion These data are the result of an Italian effort to establish in Iraqi Kurdistan a leading center for hemopoietic stem-cell transplantation. The capacity building approach was used, with on-site training and coaching as instruments for the development of provider ability and problem solving. With future limitations for immigration, this method will be helpful, especially in the field of high-technology medicine.

Amelanotic melanoma is a rare melanoma subtype, and it is even more rare when it occurs at an acral site. We here present a case of a nodular amelanotic acral melanoma (NAAM) occurring on the heel of an 83-year old female. It presented as an ulcerated pink nodular growth on the heel, which clinically mimicked other nodular non-pigmented lesions, causing a delay in diagnosis until it was biopsied. This case is a demonstration of the critical importance to include NAAM in the differential diagnosis of nodular non-pigmented skin lesions as to avoid delay in diagnosis and disease progression, in which early detection can provide the most modifiable prognostic factor.

We describe the entire process leading to the start-up of a hematopoietic stem cell transplantation center at the Hiwa Cancer Hospital, in the city of Sulaymaniyah, Kurdistan Iraqi Region. This capacity building project was funded by the Italian Development Cooperation Agency and implemented with the support of the volunteer work of Italian professionals, either physicians, nurses, biologists and technicians. The intervention started in April 2016, was based exclusively on training and coaching on site, that represent a significant innovative approach, and led to a first autologous transplant in June 2016 and to the first allogeneic transplant in October. At the time of reporting, 9 months from the initiation of the project, 18 patients have been transplanted, 15 with an autologous and 3 with an allogeneic graft. The center at the HCH represents the first transplantation center in Kurdistan and the second in wide Iraq. We conclude that international development cooperation may play an important role also in the field of high-technology medicine, and contribute to improved local centers capabilities through country to country scientific exchanges. The methodology to realize this project is innovative, since HSCT experts are brought as volunteers to the center(s) to be started, while traditionally it is the opposite, i.e. the local professionals to be trained are brought to the specialized center(s).

Ameloblastic fibro-odontoma is a rare, benign, and slowly growing neoplasm of the jaw composed of proliferating odontogenic epithelium in ectomesenchymal tissue along with dental hard tissue formation. Herein, we describe a case of an ameloblastic fibro-odontoma in 12-year-old female with paresthesia of the chin and lower lip. Panoramic radiography showed a radio-opacity in the right posterior mandible near the mandibular canal and associated with the right mandibular third molar. Histologically, the lesion contained epithelial and mesenchymal odontogenic components in close proximity to odontoma-like elements. Enucleation and curettage of the affected site in the mandible resulted in resolution of the paresthesia postoperatively.
