A rare case of small bowel leiomyosarcoma presenting with acute gastro-intestinal bleeding.

A 62-year-old Turkish female was admitted to our hospital with acute, progressive melena. Gastroscopy and colonoscopy could not reveal the cause of the melena. Subsequent CT angiography demonstrated a large, exophytic mass in the ileocecal junction as a source of the haemorrhage, leading to urgent laparotomy and resection.

Nasal paraganglioma: differential diagnosis from a radiologic and pathologic perspective.

A 33-year-old Asian male presented with spontaneous nosebleeds and olfactory sense problems for the past several years. CT scan and MRI demonstrated a large soft tissue mass in the nasal cavity and paranasal sinus with avid and homogeneous contrast enhancement, focal osseous destruction and a non-enhancing cyst at the intracranial tumour-brain margin. After complete endonasal resection, histopathological examination revealed a paraganglioma.

Extremely elevated CA-125 in benign ovarian disease due to stretch of the peritoneum.

Serum concentrations of CA-125 are rarely elevated beyond 1000 U/ml in benign conditions of the ovary in postmenopausal women. In this report, the authors present an unusual case of a 78-year-old woman with an extremely elevated CA-125 concentration of 2897 U/ml without the presence of a malignancy, ascites or pleural effusion. Imaging revealed a large intra-abdominal cystic mass with irregular solid deviations on CT scan, most likely arising from an ovary.
