Folliculitis decalvans (FD) is a chronic inflammatory alopecia characterized by painful, scarring lesions and recurrent flares, often complicated by secondary bacterial infections. Despite the use of topical and systemic anti-inflammatory or antimicrobial therapies, FD remains challenging to manage, with limited therapeutic advancements. We report a case of recalcitrant FD in a man in his 40s who experienced significant symptom improvement and hair regrowth following the initiation of tirzepatide for weight management.

Application of Ultraviolet-Induced Fluorescence Trichoscopy (UVFT) in Hair and Scalp Diseases.

Dermatol Ther (Heidelb)

January 2025

Department of Dermatology, Institute of Medical Sciences, Medical College of Rzeszow University, Rzeszow, Poland.

Introduction: Ultraviolet-induced fluorescence dermoscopy (UVFD) is increasingly utilized in dermatooncology and general dermatology. The objective of the study was to characterize the ultraviolet-induced fluorescence trichoscopy (UVFT) findings in a wide range of hair and scalp conditions.

Methods: Consecutive patients with non-scarring alopecias (alopecia areata, AA, n = 40; androgenetic alopecia, AGA, n = 40), scarring alopecias (frontal fibrosing alopecia, FFA, n = 20; lichen planopilaris, LPP, n = 20; folliculitis decalvans, FD, n = 14; discoid lupus erythematosus, DLE, n = 23), and inflammatory scalp conditions (psoriasis, n = 30; seborrheic dermatitis, n = 14) were included.

Article Synopsis
  • - Polytrichia is a common observation in folliculitis decalvans (FD), linked to compound follicular structures (CFS) that involve multiple hair follicles sharing a single opening and surrounded by fibrous tissue.
  • - A study analyzed 10 scalp biopsy samples from patients with early-stage FD, focusing on the types and quantities of follicles within these CFS.
  • - The findings revealed that of 205 follicles examined, 156 were terminal follicles, primarily in the anagen phase, providing insights into the pathology of FD.
