Incidence of Trichostasis Spinulosa at a Single Institution in Yemen

The study conducted at Al-Kuwait University Hospital in Yemen aimed to determine the occurrence and characteristics of trichostasis spinulosa (TS) among patients. Out of 2400 patients examined, 286 (11.9%) were diagnosed with TS, with a higher prevalence in women (6.3%) compared to men (4.2%). The face was the most commonly affected area, particularly the nasal alae (96.2%) and nasal tip (90.9%). Only 15.7% had forehead lesions, and 4.5% had perioral lesions. Among the 38 patients who had received prior treatment, 65.8% reported temporary improvement. The study concluded that TS is a common condition affecting the face across all ages, and further research with larger, multi-center cohorts is needed to better understand its prevalence.
