Angiomyomatous hamartoma is a rare tumour of lymph nodes. This report describes a case of angiomyomatous hamartoma in the inguinal lymph node. The patient was a 33-year-old woman who underwent surgery because of a right inguinal mass. The excised specimen consisted of a grossly enlarged lymph node covered with fatty tissue, measuring 4.5 cm in diameter. On microscopic examination, the lymph node parenchyma was replaced by haphazardly dispersed thick-walled vessels and smooth muscle cells in a fibrous background. This process extended to the cortex from the hilum, and there was a thin cortical lymphoid tissue. Immunohistochemical actin staining indicated smooth muscle cells dispersing into the fibrous background. Although angiomyomatous hamartoma of lymph nodes is very rare, its recognition is important for differential diagnosis from angiomatous malignant tumors of lymph nodes.
