A nodule present for many years on the right leg of a 77-year-old woman was excised and studied by light microscopy. An invasive keratinizing basal cell carcinoma associated with metaplastic bone formation, arising within a dermatofibroma, was found.

We report 2 cases of angiosarcoma of the prostate gland. The patients were 42 and 60 years old, which is in sharp contrast to the presentation of rhabdomyosarcoma, which occurs primarily in children. Immunoperoxidase staining for factor VIII associated antigen was positive in both cases, and was particularly useful in confirming the diagnosis in 1 case that was otherwise poorly differentiated. One patient is alive without evidence of recurrence 2 years after surgical excision, while the other presented with unresectable tumor and died 6 months after presentation. Angiosarcoma represents less than 2 per cent of sarcomas of the prostate but it should be considered in the differential diagnosis of poorly differentiated sarcomas, particularly those occurring in adults.

A case of right subdiaphragmatic extralobar pulmonary sequestration (PS) associated with a gastric duplication cyst is reported. To the authors' knowledge such a case has not been reported previously in the English literature. PS was first noted as a defect on a nuclear liver image. The duplication cyst was defined by ultrasonography. A review of the English literature is included.
