Angiomyomatous hamartoma (AMH) is a rare and benign mixed-tissue tumor of the lymphatic system. The majority of AMH tumors are removed surgically for cosmetic reasons or during workup of lymphadenopathy. There are few reported cases of this condition in the literature; AMH does not cause pain, and there are no published reports of AMH recurring after surgical excision. Here, we report a unique case of inguinal AMH recurring after surgical excision and causing a painful compression neuropathy. Our report also describes the patient’s successful but transient response to nonsurgical pain management.
