AGGRESSIVE ANGIOMYXOMA OF SCROTUM PRESENTING AS AN INGUINAL HERNIA

Aggressive Angiomyxoma (AAM) is a rare mesenchymal tumor with a locally aggressive course. The most common location is in the pelviperineal region and occurs mostly in females of childbearing age. In males, it is extremely rare and thus is apt to be mistakenly diagnosed as an inguinal hernia or hydrocele. We report a case of 45 year old man who had right sided scrotal swelling for about four years. It was diagnosed as an inguinal hernia clinically. On further investigations, it was found to be a soft tissue tumor of the scrotum. The patient underwent scrotal exploration. At surgery, a huge lobulated gelatinous mass surrounding the right testicle was found. The mass was excised including the testicle and sent for histopathological analysis. Histologic examination of the excised mass revealed a nonencapsulated lesion composed of sparse spindle-shaped cells and a myxoid stroma with a prominent vascular component. The cells showed focal and weak positivity for desmin. The findings were thus consistent with aggressive angiomyxoma of the scrotum. The margins of the specimen were clear. The patient we report has so far done well with no evidence of recurrence.
