Paratesticular angiomyofibroblastoma: case report and review of the literature.
Angiomyofibroblastoma is a rare, benign, mesenchymal tumour occurring mainly in the female genital tract, and more rarely, in males. We present a new case of angiomyofibroblastoma arising in the left inguinal region of an 83-year-old man. The tumour was well circumscribed and measured 60 mm in maximum dimension. On microscopic examination, the tumour was composed of small spindle cells without atypia within a fibrous and myxoid stroma where scattered mononuclear inflammatory cells were found around the capillaries of the stroma. Immunohistochemical studies showed positive staining of tumour cells for vimentin, desmin, smooth muscle actin and CD34, and negative staining for PS100 and oestrogen and progesterone receptors. These histological findings are consistent with angiomyofibroblastoma. The patient was followed up for 4 years without recurrence.
