Case for Diagnosis: Pregnant Woman in the Third Trimester with Pruritic Papules and Pustules on the Trunk. Pruritic Folliculitis of Pregnancy

The document presents a case study of a 26-year-old pregnant woman in her 31st week of gestation who developed pruritic skin lesions on her trunk. The histopathological analysis of a biopsy from a dorsal pustule showed a lymphocytic perivascular infiltrate and a hair follicle permeated by an inflammatory infiltrate, leading to the destruction of the follicular structure. The patient was diagnosed with Pruritic folliculitis of pregnancy (PFP), a rare, benign, and self-limited gestational dermatosis. The patient was treated with 5% benzoyl peroxide gel, leading to complete regression of the lesions in the first week of postpartum. The document emphasizes that PFP does not interfere with maternal-fetal morbidity and mortality, and it is essential for pregnant women to be adequately diagnosed, advised, and followed-up with specialized care.
