Aggressive angiomyxoma is a rare, locally invasive, but nonmetastasizing soft-tissue tumor that most commonly occurs in the pelvis or perineum of premenopausal women. In this article, we report two cases of aggressive angiomyxoma that occurred in middle-aged men. Although both patients initially presented with inguinal hernias, in other respects the two cases were significantly different. In one case, the tumor was small and found only incidentally at the time of surgery. In the other case, the tumor was extremely large, primarily involved the scrotal soft tissue, and was clinically thought to represent a testicular tumor.
