Para-testicular cellular angiofibroma: a rare tumour in a male renal transplant patient.

Cellular angiofibroma is a rare, benign, mesenchymal neoplasm that should be distinguished from other more aggressive mesenchymal lesions. A 32-year-old male presented with a painless para-testicular mass. Pathological examination showed features characteristic of cellular angiofibroma. He had a history of renal transplantation and was on immunosuppressive drugs. The pathogenesis of cellular angiofibroma is largely undetermined. The role of immunosuppressive therapy in the genesis of this tumour awaits further analysis.
