We report on two cases of aggressive angiomyxoma (AAM) of the spermatic cord occurring in two 13-year-old children. Clinically, the tumor simulated a mass of the spermatic cord. Histologically, it represented a poorly circumscribed, benign myxoid tumor, with a sparse population of stromal cells immunoreactive for vimentin and, focally, for smooth muscle actin. No immunostaining for desmin, S-100, p53, p21waf-1, c-Erb-B2 and estrogen-progesterone receptors was found. High proliferating cell nuclear antigen (PCNA) immunoexpression found in most of the tumor cells may explain the high risk of recurrence. AAM should be considered in the differential diagnosis of a spermatic cord mass occurring during infancy.
