Adult-onset eccrineangiomatous hamartoma treated with excision and skin grafting: a case report

Abstract

<p>Eccrine angiomatous hamartoma is a rare benign tumour like malformation characterized by intradermal proliferation of eccrine and vascular components. It usually arises before puberty but can occur at any age. It typically presents as a solitary or multiple reddish or brownish plaque or nodule that progressively enlarges in size. Symptoms such as pain and hyperhidrosis may be associated. Lesions are commonly located over distal extremities. We report a case of a 45-year-old lady who presented with a gradually enlarging solitary reddish plaque over the left retro-auricular region of the scalp since the last 12 years and associated with occasional pain. Histopathology revealed pproliferation of eccrine sweat glands and thin-walled blood vessels in the dermis. Additional ultrasound and MRI contrast studies were done to assess the vascular component and involvement of underlying structures. The patient was treated successfully with complete excision of the lesion followed by split thickness skin grafting.</p><p><strong> </strong></p>
