ECCRINE ANGIOMATOUS HAMARTOMA

A g‐year‐old girl was seen at our outpatient department with a 5‐year history of a slowly enlarging hyperpigmented area with increased sweating on the right upper chest and back. There was no history of pain or tenderness over the lesion. She was the second child of a nonconsanguineous marriage. The older sibling was healthy and there was no family history of similar complaints. Dermatologic examination revealed a large hyperpigmented plaque involving the right upper chest, extending over the right shoulder to the back (Fig. 1). The margins were well defined with raised borders on the upper part; elsewhere it gradually merged with the adjacent normal skin. Two other well‐defined hyper‐pigmented plaques were seen, one 3 × 3 cm over the nape of neck and another 3 × 1 cm over the right supraclavicular fossa. The lesions were nontender and noncompressible. There was increased sweating on the plaque following physical exertion and the plaque could be mapped out with starch and iodine (Fig. 2). Systemic examination of the child was within normal limits. Routine blood and urine examination was normal. Histologic sections showed an increased number of cross‐sections of sweatglands interspersed with dilated vascular spaces, filled with blood, in the mid and lower dermis (Figs. 3 and 4).
