ABSTRACT
An eccrine nevus is a rare hamartoma characterized by an increase in the number or size of eccrine glands. Eccrine nevi usually present as localized hyperhidrosis and are not associated with overlying skin abnormalities. However, among the cases that have been reported in the literature, some unique presentations of eccrine nevi have been demonstrated, including a pigmented patch, a depressed nodule, linear papules, and a sacral skin tag. Herein, we report two unusual cases of coccygeal polypoid eccrine nevi and review the literature.

Eccrine nevi are very rare cutaneous lesions which may or may not be accompanied by localized hyperhidrosis. Histological findings usually reveal a slightly increased number of eccrine glands without any other abnormalities. Herein we present a case of eccrine nevus not associated with localized hyperhidrosis on the left wrist of a 6-year-old girl. The lesion was a brownish, ovoid plaque approximately 1.0 x 1.5 cm in size, with a hyperkeratotic, slightly scaly papule in the center. It was treated by surgical excision.

Eccrine nevus is a rare benign cutaneous lesion, frequently present at birth or at an early age. Herein we report on a 1-year-old girl with erythematous papules in a zosteriform arrangement associated with hyperhidrosis on the left side of her trunk.

A 2-year-old girl had variably-sized, relatively well demarcated, depressed brownish patches on the left shoulder, back, and both legs from the age of 1 month. The biopsy specimen from the left shoulder showed an increase in the number of normal intradermal eccrine ducts and coils, which was compatible with pure eccrine nevus. The clinical manifestation of our case, including brownish depressed patches, was unique compared to other reported cases.

Eccrine nevus is an unusual entity with various clinical manifestations. Histologically the eccrine apparatus appears simply increased in number and/or size, but structurally normal. We present a case of eccrine nevus on the dorsum of the left 3rd and 4th fingers in a 20 year-old female. The lesions were 3 × 2cm sized, well demarcated, smooth surfaced, brownish plaques with mild hyperhidrosis. Histological examination revealed hyperkeratosis in the stratum corneum and hyperpigmentation of basal layer, and an increased number of eccrine sweat glands and many eccrine coils in the dermis was seen.
