Epithelioid cell granulomas may be associated with several neoplasms. Lymphomas may mimic or are associated with epithelioid granulomas. In this article the authors report a child with granulomatous reaction in B cell non-Hodgkin lymphoma and intracardiac thrombosis. Although cancer alone is a risk factor for thromboembolism, thrombosis is a multifactorial disorder with both hereditary and acquired risk factors. This is the first reported case of intracardiac thrombosis with MTHFR A1298C and factor XIII V34L mutations together with granulomatous reaction in non-Hodgkin lymphoma.

OBJECTIVE Lymphoscintigraphy (LS) and sentinel lymph node biopsy have become the standard of care for melanoma and breast cancer. However, the data on patients with cutaneous squamous cell carcinoma (SCC) are limited. We aimed to evaluate and identify the role of LS and sentinel lymph node biopsy in patients with high-risk cutaneous SCC. METHODS Nineteen patients (13 men, six women; 47-87 years of age, mean age 67.5 ± 12.3) with SCC were included in the study. LS was performed on all patients after intracutaneous injection of Tc-99m nanocolloid. Primary lesions and sentinel lymph nodes (SLNs) were excised with the help of a gamma probe. RESULTS A total of 26 SLNs and 32 secondary lymph nodes were imaged on LS and were marked. During surgery, 29 SLNs, 21 secondary lymph nodes and three nonactive lymph nodes were excised. In total, 53 lymph nodes were removed surgically. A histopathological study revealed that all lymph nodes were negative for metastasis. Patients were followed up for an average of 41.1 ± 22.2 months (7-80 months). Until the time of data collection, 14 patients were alive and had no regional lymph node or distant metastasis. Local recurrence was seen in only one patient. He was reoperated upon 38 months ago. CONCLUSION The feasibility of determining SLNs using LS and an intraoperative gamma probe in patients with cutaneous SCC was shown. Unnecessary elective lymph node dissection and possible complications could be avoided in 19 patients.

Acute renal failure is a well-recognized complication of acute leukaemias. Howevcr, serious renal failure caused by leukaemic infiltration as a primary manifestation is unusual. Here we report two patients with acute lymphoblastic leukaemia presenting with acute renal failure due to leukaemic infiltration. The first patient died before the administration of specific therapy for leukaemia, whereas the second case recovered after chemotherapy. She was discharged without necessitating dialysis therapy.

To present a case of primary malignant melanoma of the cervix. The patient was admitted with the complaint of vaginal bleeding. Gynecological examination revealed a dark, papillary mass on the posterior lip of the cervix. Histopathology showed a malignant neoplasm with increased vascularity, indicating the possibility of a primary uterine cervical melanoma. Diagnosis of malignant melanoma was confirmed with immunohistochemistry, which showed diffuse positive reactions for S-100 protein and HBM-45, with no reaction for epithelial markers, namely cytokeratin AE1/AE3 and epithelial membrane antigen. An extensive search for a melanotic lesion in skin and in uveal tract was performed to verify the distinct site of melanoma. The tumor was stage IB1 according to the International Federation of Gynecology and Obstetrics classification.The patient underwent radical Wertheim–Meigs hysterectomy, bilateral salpingo-oopherectomy, and retroperitoneal pelvic lympadenectomy. Radiotherapy or chemotherapy was not performed in the postoperative period. She is now free of the disease 10 months after the operation. Primary malignant melanoma of the cervix is a rare cervical malignancy.

This article describes a case of a 44-year-old woman with a history of IUD use that was found to be suffering from an uncommon infectious disease abdominal actinomycosis. It states that abdominal actinomycosis must be considered among the differential diagnosis of infiltrating intra-abdominal disorders especially in women with history of IUD use.
