    ABSTRACT: A 39-year-old woman with inflammatory bowel disease was admitted to the hospital because of cramping abdominal pain and diarrhea. Ultrasound of the abdomen revealed thickening of the wall of the descending colon. At endoscopy mucosa-covered nodules with substenosis were seen. A double-contrast examination showed narrowing in the transition zone between the descending colon and sigmoid with mucosal nodularities and barium spots in between. Examination of the resection specimen revealed colitis cystica profunda. After surgical treatment the history of the patient was uneventful.

    ABSTRACT: A 67-year-old man presented with weight loss, intermittent severe abdominal pain and melaena. Initial radiology (including abdominal ultrasonography), gastroscopy and colonoscopy did not demonstrate any lesions that could explain the complaints. Three weeks later, upper gastrointestinal and small-bowel barium studies revealed two areas in the small intestine with an abnormal mucosal pattern. Explorative laparotomy revealed three tumoral lesions. Three partial enterectomies were performed. Gross examination showed centrally depressed dark reddish tumoral lesions extending from the mucosa throughout the full thickness of the bowel wall (diameter varying between 1.6 cm and 2.2 cm). The tumours, composed of large, plump, polygonal cells showing little architectural differentiation, were mainly situated in submucosa and muscularis propria. The growth pattern appeared rather solid. The epithelioid cells showed pronounced nuclear pleomorphism and atypia with central large nucleoli. There were several small blood vessels with occasional anaplastic endothelial cells. Immunohistochemical staining demonstrated an intense expression of CD 31, CD 34, factor VIII related antigen and keratin. This supported the diagnosis of an epithelioid angiosarcoma. The patient died 3 months after diagnosis. Tumours of the small intestine are very rare, and angiosarcomas of the small intestine are even more rare. Epithelioid variants have only been described in two patients and only one of these had a multifocal presentation. The prognosis is very poor. Because of the epithelioid growth pattern and the cytokeratin expression, these tumours may erroneously be diagnosed as a carcinoma.

    ABSTRACT: At 32 weeks of gestation, delivery of a female fetus was induced because of severe malformations seen on ultrasonogram: congenital diaphragmatic hernia and cerebellar hypoplasia. The diagnosis of Coffin-Siris syndrome was based on the physical examination: coarse face with low-set ears, low nuchal hairline, scalp hypotrichosis and hypoplasia of the nails of fingers and toes with absence of the right fifth fingernail. Autopsy confirmed the prenatally diagnosed major associated abnormalities: hypoplasia of the cerebellum and congenital diaphragmatic hernia. Various clinical entities are included in the differential diagnosis.
