A Solitary Halo Neurofi broma-A Case Report

Halo neurofi broma is a rare benign tumor. In the past, 3 cases of multiple halo neurofi bromas and 1 case of a solitary halo neurofi broma have been reported. The neurofi broma is characterized by a skin-colored, dome-shaped soft papule or a nodule surrounded by hypopigmented macules. The pathogenesis of neuroectodermally derived tumors associated with halo phenomenon is still poorly understood. We report a case of a 46-year-old female with a solitary halo neurofi broma and discuss the possible causes. (Dermatol Sinica 27: 181-185, 2009)
