Congenital eccrine angiomatous hamartoma: Expanding the morphologic presentation and a review of the literature.

Eccrine angiomatous hamartoma (EAH) is a rare benign vascular hamartoma characterized histologically by an increased size and number of mature eccrine glands associated with multiple foci of dilated capillaries in the dermis and subcutis. EAH typically presents in children as discrete, solitary nodules, or plaques most commonly located on the extremities. Some cases of EAH have an agminated distribution involving classic locations, or present as solitary lesions in less common locations such as the face, scalp, or trunk. We report the case of congenital EAH in a child with atypical morphological features and pattern of distribution further expanding on the range of presentations classically described.
