Angiomyomatous hamartoma is a primary vascular tumor primarily found in the inguinal and femoral lymph nodes characterized by the replacement of nodal tissue by smooth muscle cells and fibrous tissue in sclerotic lymphatic stroma. There has been I report of an angiomyomatous hamartoma of a cervical lymph node, and this is the first reported case occurring in an extremity. We present a case of angiomyomatous hamartoma occurring in a single popliteal lymph node. (c) 2008 Elsevier Inc. All rights reserved.
