A 10‐year‐old girl with gray‐brown patches in the axillary and inguinal folds.

This article presents a case study of a 10-year-old girl with gray-brown patches in the axillary and inguinal folds. The girl had been unsuccessfully treated with topical cream and oral medication for a presumed tinea infection. Further examination revealed gray-brown macules and patches in the affected areas, as well as perifollicular pigment deposits. Biopsies confirmed the diagnosis of lichen planus pigmentosus inversus (LPPI). LPPI is a rare variant of lichen planus characterized by asymptomatic or mildly itchy pigmented lesions in skin folds. Treatment options include topical corticosteroids or calcineurin inhibitors. [Extracted from the article]
