Abstract:
Trichostasis spinulosa was first described by Nobl in 1913 to denote a condition characterized by protruding groups of hairs embedded in horny mass on the nose, forehead, shoulder, and back. We report a case a 27-year old male patient with trichostasis spinulosa who showed multiple black colored papules on his back and upper arms. Histologic examination showed hair follicles surrounded by hyperkeratotic band which had multip]e hairs. By scanning electron micnoscopy, also, we could find several hairs of different size in the hyperkeratotic hair shealh.
