Eccrine Angiomatous Hamartoma : A Rare Entity 4

Eccrine angiomatous hamartoma (EAH) is an exceedingly rare benign tumor-like lesion, mostly develops before 1 adulthood as single slow growing lesion on extremities, may produce pain and marked sweating. Presentations are manifold and the naevi are not always present from birth. The histological features include proliferation of eccrine sweat glands and angiomatous capillary channels. We report a 13 year old male who had a single lesion on his right thigh for last 4 years. Physical examination revealed a slightly elevated, 8x6 cm blackish-brownindurated, tender plaque on the posterolateral aspect of right thigh. Sweating in the lesion was evoked by physical work or emotional stress. Histopathological examination of the lesion showed increased numbers of eccrine glands, ducts and neural tissue as well as dilated vascular channels in the superficial and deep dermis. These findings are consistent with EAH. We report this case due to rarity of its presentation.
