Lichen‐planopilaris‐like scarring pattern in a patient with alopecia and pityriasis rubra pilaris
September 2020
in “Journal of Cutaneous Pathology”
TLDR A patient with a skin condition had unusual scarring hair loss but improved with treatment.
In the article from September 30, 2020, a 69-year-old woman with pityriasis rubra pilaris (PRP) developed a rare scarring alopecia resembling lichen planopilaris, which is unusual since PRP typically causes non-scarring alopecia. Following an erythrodermic episode and telogen effluvium, scalp biopsies indicated lichen planopilaris-like features. Despite the typically poor prognosis of such conditions, the patient's hair loss responded positively to treatment with clobetasol, oral minoxidil, and triamcinolone infiltrations. This led to a significant clinical improvement and the regrowth of eyebrow hair. The case highlights the potential for a favorable outcome with early intervention in scarring alopecias that present with lichen planopilaris-like patterns.
