“…There are a few reports in the literature that were interested in the contribution and the implications of dermoscopy in facial TS, most of them are case reports [4-6]. The diagnosis of TS may be based only on dermoscopic findings of tufts of VH with varying diameters emerging from dilated follicular openings [4] and FK [1].…”

Background: Data about the contribution and the implications of dermoscopy in trichostasis spinulosa (TS) are lacking in the literature. Objective: To describe dermoscopic features of TS in a large sample of patients and to correlate dermoscopy with clinical characteristics of the patients and therapeutic responses to medical treatments. Methods: A descriptive study was conducted (from October 2015 to June 2016) at the Department of Dermatology of Fez in Morocco. Dermoscopic signs were divided into signs of hair retention (SHR) and follicular keratosis (FK). Results: SHR was severe in 8.8% and minimal in 40.5% of all cases. Vellus hairs were observed in 81.6% of all cases and hair tufts were described in 48.7%. Dermoscopic blackhead-like structures (DBH) were found in 53.9% of all cases. FK was observed as orange-yellowish keratotic plugs in 92.7% of all cases. Therapeutic demand was significantly related to female gender (p = 0.002) and recurrences after medical treatment (p = 0.004). Complete improvement after medical treatment was only described in patients with DBH and minimal SHR (p = 0.001). Conclusion: Dermoscopy not only increases the accuracy of the clinical diagnosis in TS, but a new description of dermoscopic classification has also been proposed leading to therapeutic implications.

“…[15] Less commonly, it is observed in association or found to develop within other cutaneous conditions as mentioned above (secondary TS). [7,17] e onset is usually after adolescence, elderly being most affected perhaps due to prolonged actinic damage. Childhood cases are rare.…”
