Abstract

Eccrine angiomatous hamartoma is a rare, benign malformation, of unknown aetiology, histologically characterized by capillary and eccrine glandular proliferation. It begins more frequently at birth or during childhood, presenting with a patch, plaque or nodule growing proportionally to the child’s growth. It can present with hyperhidrosis, hypertrichosis and pain. We report the case of a 3-year-old boy who was referred by 3 lightly brownish hyperpigmented patches, with more than 20cm long each, irregular borders, hypertrichosis, at the left thoracolumbar region. At friction, lesions became more vivid, with an evolution from 6 month-old with hyperhidrosis. The biopsy confirmed eccrine angiomatous hamartoma diagnosis. Due to the lesion’s benign nature and subtle symptomatology it was decided not to perform any treatment. Eccrine angiomatous hamartoma is a rare entity and this case, to the best of our knowledge, is the biggest one described until now.
