Abstract

We report 2 cases of congenital porokeratotic eccrine nevus in a 5-year-old girl and a 7-year-old boy. The clinical manifestations were those of nevus comedonicus palmaris. The histologic picture consisted of comedo-like dilatations and cornoid lamellae involving the eccrine ostia and ducts. One of the cases showed anomalies in the dermal eccrine ducts. We believe that these lesions are eccrine hamartomas unrelated to porokeratosis. We review similar cases from the literature and discuss the differential diagnosis.

摘要

我们报告了2例先天性汗孔角化性小汗腺痣，分别发生在一名5岁女孩和一名7岁男孩身上。临床表现为掌部粉刺样痣。组织学表现为粉刺样扩张和累及小汗腺开口及导管的鸡眼样板层。其中1例真皮小汗腺导管有异常。我们认为这些病变是与汗孔角化病无关的小汗腺错构瘤。我们回顾了文献中的类似病例并讨论了鉴别诊断。
