Synchronous presence of cellular angiofibroma and lipoma in vulvoinguinal region: a unique case report.

A 26-year-old woman presented with a 7-month history of a slowly growing right-sided, well-circumscribed, subcutaneous, soft, painless, large vulvoinguinal lump that now measured up to 12 cm. Adjacent to but separate from this was a well-circumscribed, soft, painless, mobile, large inguinal tumor 8 cm in diameter that had been present unchanged for 2 years. Both lesions were completely excised. Histologically, the first mass was consistent with cellular angiofibroma, whereas the second one had the typical features of lipoma. According to the available literature, this is the first case of synchronous presence of cellular angiofibroma and lipoma in one patient.

Angiomatosis: a case with metaplastic ossification.

Angiomatosis is defined as a hemangioma that affects a large segment of the body in a contiguous fashion, either by vertical extension to involve multiple tissue planes (eg, skin, subcutis, muscle, bone) or by crossing muscle compartments to involve similar tissue types (eg, multiple muscles). Such lesions usually present in the first 2 decades of life and have a highly characteristic but not totally specific histological pattern. Histology usually shows a haphazard mixture of small and medium-sized vessels, fat, connective tissue, and lymphatics. Large amounts of mature fat frequently accompany the vascular elements, suggesting that the lesion may possibly be a more generalized mesenchymal proliferation rather than an exclusively vascular lesion. Here we present what we believe to be the first case of angiomatosis showing osseous metaplasia.
