Borderline serous cystadenocarcinoma with coexistent angiosarcoma: an unusual form of ovarian carcinosarcoma.

A 45-year-old woman presented with a short history of abdominal distension and features of intestinal obstruction. Computed tomography examination of the abdomen revealed a solid and cystic mass in the region of the left ovary, but spread within the abdomen was also noted. The ovarian tumor was removed, and an omentectomy was also performed. Microscopic examination of the ovarian tumor and metastases within the omentum showed a carcinosarcoma composed of borderline serous papillary cystadenocarcinoma and angiosarcoma. The angiosarcomatous component was the dominant tumor within the omentum. This case documents an unusual combination of epithelial and sarcomatous elements in an ovarian carcinosarcoma. The tumor behaved aggressively because of the angiosarcomatous component, and since the patient was assessed as having stage IV disease, no further treatment was offered.

Pacinian collagenoma.

An unusual histological variant of collagenoma is described. A 36-year-old woman presented with a lump in the left hypothenar eminence. Histological examination revealed a well-delineated lesion composed of paucicellular collagen fibres arranged in concentric lamellations giving rise to an onion skin appearance. The overlying epidermis was thin and the lateral borders were demarcated by an epidermal collarette. Inflammation and xanthoma cells were absent and occasional capillaries were present. The lesion was positive for collagen stains, reticulin and CD34. This lesion represents an uncommon histological form of collagenoma or fibroma. It can be distinguished from histological look-alikes on the basis of the characteristic morphology and immunophenotype.

Malakoplakia and tuberculosis.

A 33 year old woman developed a soft mass in the left anterior neck following treatment for pulmonary tuberculosis. An incisional biopsy was performed and a cold abscess drained. Histology confirmed a diagnosis of tuberculosis. In addition, there were numerous intracellular bodies which resembled the Michaelis-Gutmann bodies of malakoplakia. This case however displayed some atypical histological, histochemical and ultrastructural features, which are highlighted in this report. The mass responded to combination antituberculous treatment.

Ileal diverticulosis in a black patient. A case report.

A 54-year-old black man presented to hospital with diarrhoea containing blood and mucus and marked loss of weight over a 1-year period. Barium enema examination revealed cobblestoning and rose-thorn ulceration with possible stricture formation of the terminal ileum. A right hemicolectomy was performed to remove inflamed sections of small and large bowel. Histological examination of the resected specimen demonstrated features of ileal diverticular disease. This is the first documented case of this disease occurring in a black patient.
