Abstract

Epidermal nevus syndrome is a clinically variable and genetically heterogeneous group of mosaic conditions characterized by the concurrence of extensive epidermal nevus with additional cutaneous and extracutaneous manifestations. This term groups together well-characterized clinical entities, as well as dozens of apparently unique associations, which need further delineation. We report on a 23-year-old woman presenting the previously undescribed combination of widespread eccrine proliferation, multiple facial and oral pox-like lesions, gingival synechiae, blepharophimosis, body asymmetry, and mental retardation. The patient has a healthy monozygotic twin. The eccrine proliferation is intermingled with areas of unaffected skin with a linear/segmental distribution on the limbs. The clinical presentation of such a complex phenotype fits well with the genetic mosaicism theory. The histologic findings, consisting of proliferation of immature to well-formed eccrine duct-like structures located in the deep dermis and interspersed with an abundant fibrous stroma constituted of horizontally oriented collagen fibers, seem a possible hallmark of this condition.
