Research output: Contribution to journalArticlepeer-review


Trichostasis spinulosa is a relatively common follicular disorder that results from the retention within a single follicle of successive vellus hairs. It is characterized clinically by numerous follicular spines resembling comedones located on the seborrheic areas. On histologic examination, trichostasis spinulosa is characterized by dilated hair infundibula containing numerous hair shafts enveloped in a keratinous sheath. We report a case of trichostasis spinulosa within an intradermal melanocytic nevus, which developed in a 44-year-old man.
