A case report of adult onset eccrine angiomatous hamartoma: A rare entity

Abstract

Abstract Intoduction: Eccrine angiomatous hamartoma (EAH) is an extremely rare and benign malformation in adults which presents with single or multiple nodules or single large plaque over the extremities at birth with pain and marked sweating. On histopathological examination,there is increased proliferation of eccrine sweat glands and capillary vessels in the dermis. Herein we report a 43 year-old male who presented with a single hyperpigmented plaque over the hypothenar eminence of right palm associated with excessive sweating for 3 months duration.Biopsy from the lesion was suggestive of eccrine angiomatous hamartoma.This case has been reported due to it’s unusual adult onset. Keywords: Eccrine angiomatous hamartoma, EAH, Benign tumor, Adult onset. Introduction Eccrine angiomatous hamartoma (EAH) is a rare and benign tumor, histologically characterized by increased number of dilated eccrine glands and capillary vessels. It was first described in 1859 by Lotzbeck as an angiomatous lesion on the cheek of a child and later EAH was coined in 1968 by Hyman and coworkers.[1] [2]EAH may appear as flesh colored, blue brown, yellow or reddish macule, plaque or nodule associated with exquisite pain on palpation and hyperhidrosis. Asymptomatic lesions do not require any treatment. It is important to recognize this benign clinical entity, for which aggressive treatment is not necessary.?1; Case Report A 43 year old male, working as a supervisor in a hotel came with complaints of hyperpigmented plaque over right palm for 3 months duration which started as a small red itchy plaque. It was associated with excessive sweating over the plaque and pain following local pressure and physical exertion. No history of trauma or similar lesions in other parts of the body. No history of atopy. No history of hypopigmented patches or altered sensations over the extremities. Clinical Examination A solitary, well defined, hyperpigmented plaque of 5x3cm
