“…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]. Microscopic and histologic examination does not add any other findings.…”

“…Body lesions of TS were not evaluated. The diagnosis of TS was confirmed based on dermoscopic findings as one or tuft of VH with varying diameters emerging from dilated follicular openings, with keratotic plugs filling the follicular openings and surrounding VH [1]. …”

“…Trichostasis spinulosa (TS) is a relatively common but underdiagnosed follicular disorder, it is a congenital dysplasia of the hair follicles with an abnormal angulation between the isthmus and the infundibulum and an entrapment of up to 50 small vellus hairs (VH) in a hair follicle [1, 2]. Facial TS is characterized by hyperkeratosis of a dilated hair follicle with retention of multiple telogen VH, it appears clinically as asymptomatic blackhead comedo-like lesions on the tip of the nose, the alae of the nose, and the cheeks [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.

This chapter reviews acquired hair disorders, including common scarring and non‐scarring alopecia presentations, conditions characterised by excessive body hair growth and acquired hair shaft disorders. We also describe the biology of normal hair follicles, including structure, hair cycle control and immunity, to better understand the mechanisms underlying these conditions. We present methods for clinical assessment, recommended investigation and management of each disease, and present summaries of frequently used therapeutics and cosmetic options employed when treating these problems.
