ABSTRACT
Angiomyomatous hamartomas are mixed-tissue benign lymphatic tumors that typically occur in the inguinal or axillary lymph nodes. These lesions may cause local lymphedema and painful compression neuralgias. Ultrasound-guided percutaneous cryoablation is an interventional technique that has been shown to provide sustained pain relief for peripheral neuropathies and neuralgias. Previously, our group published a case report of a patient with an inguinal angiomyomatous hamartoma causing a compression neuralgia, whose pain was temporarily alleviated after blockade of the femoral branch of the genitofemoral nerve. We present a follow-up case report describing this patient's sustained pain relief after cryoablation therapy.

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.
