The document reported a case of pseudofolliculitis barbae induced by oral minoxidil in a 61-year-old Afro-Caribbean man with a history of hypertension, glaucoma, and gout. The patient experienced tender, inflamed papules and pustules with keloid scarring in the beard area, cheeks, and posterior scalp. Examination revealed ingrowing hairs and large pustules, and microbiology tests identified Proteus mirabilis, Enterococcus faecalis, and mixed anaerobes. Histological analysis showed chronic inflammatory infiltrates destroying hair follicles, leading to a giant cell reaction and fibrosis. The clinical diagnosis was pseudofolliculitis barbae and acne keloidalis nuchae.
