Abstract:
Trichost.asis Spinulosa consists of several fasciles of reta ned vellus hairs in the hyperkeratotic sebaceous follicles, resulting in a dark slightly raied horny follicular spines, resembling comedones on the trunk and face. The condition is relatively common, particulary among the age, but is usually overlooked on routine skin examination as the patient is rarely aware of it.. We report 6 cases of trichostasis spinulosa, which showed numerous asymptomatic tiny black comedo-like dots on their backs. We obtained the follicular material by tweezer, which consised of several vellus hairs surrounded by a keratinous plug. Histologic examination was done in 3 patients, one of whom showed a rarely reproted double follicle and double papilla. With scanning electron microscopy, we observed multiple vellu hairs embedded in a keratotic plug, emerging from a hair follicle opening.
