title: Nonscarring alopecia associated with solitary circumscribed neuroma.
abstract: We report an unusual case of nonscarring alopecia clinically resembling patchy alopecia areata around central solitary circumscribed neuroma. Prompt and spontaneous complete hair regrowth was observed after removal of the tumor. Further knowledge of growth factor and receptor interaction in regulating the hair follicle cycle, as well as on the production of growth factors and cytokines by tumor cells and/or cells within the tumor microenvironment may contribute to better understand the pathologic mechanisms underlying certain curious phenomena such as peritumoral nonscarring alopecia.
