Summary: | <p>Abstract</p> <p>Introduction</p> <p>Aggressive angiomyxoma is a rare myxoid mesenchymal tumor of the pelvis and perineum, which occurs almost exclusively in adult women. The tumor is especially rare in men.</p> <p>Case presentation</p> <p>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.</p> <p>Conclusions</p> <p>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.</p>
