The tumor is especially rare in men. Case presentation We report the case of a 68-year-old Japanese man with a slowly growing inguinal swelling. At surgery a huge mass in the soft tissue of the inguinal region was found not involving the adjacent organs. The morphologic picture was compatible with aggressive angiomyxoma of the inguinal region. Conclusions Aggressive angiomyxoma is a very rare locally infiltrative neoplasm. Thus after surgery close follow-up is needed because of a high risk of local recurrence. Introduction Aggressive angiomyxoma is a rare mesenchymal tumor of the pelvis and perineum that occurs almost exclusively in adult women 1 . It preferentially arises from the soft tissue of the pelvic region perineum and genital area. Its incidence is approximately sixfold higher in women and 24 male cases have been reported in the literature 1 . The tumor is usually locally infiltrative and has a high rate of local recurrence after surgical excision 1 . The adjective aggressive emphasizes the neoplastic character of the blood vessels its locally infiltrative nature and the high risk of local recurrence not indicating a malignant potential of the lesion. Rarely this tumor appears in men simulating inguinal hernia testicular neoplasm spermatic cord neoplasm hydrocele or spermatocele 2 3 . Case presentation A 68-year-old healthy Japanese man presented with a slowly growing swelling of the soft tissue in the inguinal region Figure 1 . The duration of symptoms was about five years. At surgery a large encapsulated mass cm was found not involving the adjacent structure. The tumor was .
