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.
