Angiomyomatous hamartoma of lymph nodes: Clinicopathological study of 6 cases with review of literature.

Angiomyomatous hamartoma (AMH) is a rare disease with predisposition for inguinal and femoral lymph nodes. Histologically, it is characterized by replacement of lymph nodal parenchyma with irregularly distributed thick walled blood vessels, haphazardly arranged smooth muscle cells, variable amount of fat and fibrous tissue in a sclerotic lymphatic stroma. Few cases have also been reported in popliteal and sub - mandibular location. The exact pathogenesis is still not known. Although this entity is very rare, its recognition is important in discriminating it from other benign and malignant vascular lesions of lymph nodes.
