title: Pruritic folliculitis of pregnancy.
abstract: Pruritic folliculitis of pregnancy is a rare disease of unknown etiology. It occcurs primarily during pregnancy, usually with spontaneous resolution postpartum. It is characterized by a benign dermatosis, with papular and pustular follicular lesions that first appear on the torso and occasionally spread throughout the body. We report the case of a patient in the 27th week of pregnancy, with a two-month evolution of pruritic and papular erythematous lesions on her lower back. Differential diagnosis includes other pregnancy-specific dermatoses: gestational pemphigoid, pruritic urticarial papules and plaques of pregnancy (PUPPP), prurigo of pregnancy, and (PUPPP) and prurigo of pregancy. Histopathological tests showed changes consistent with pruritic folliculitis of pregnancy. This case is relevant due to its rare nature and its clinical and histopathological characteristics.
