Cellular Angiofibroma of the Spermatic Cord.

Cellular angiofibromas are rare, slow-growing mesenchymal tumours, most often localised in the vulva and perineum of women. We present a case of a 60-year-old male with a 7-cm large cellular angiofibroma in the inguinal canal extending toward the testis, detected after inguinal herniorraphy. Inguinal orchiectomy was performed and the pathology report revealed a cellular angiofibroma containing a lot of mast cells in the stroma, which was collagenised with spindle-shaped cells and characterised by hyalinised vascular structures. The localisation and nature of this type of mass makes initial diagnosis difficult. Differential diagnosis is important to rule out histologically malignant aggressive angiomyxomas and other solitary fibrous tumours. As local recurrence may occur after resection, long-term follow-up is necessary. © Georg Thieme Verlag KG Stuttgart · New York.
