A Case of Cutaneous Dirt-Adherent-Like Sweet Syndrome in Pregnancy

Pregnancy-associated Sweet syndrome (PASS), is a diagnostically challenging entity, especially in atypical presentations. Delayed management may result in significant maternal-fetal risks. We describe a 24-year-old woman with PASS presenting like cutaneous dirt-adherent disease, characterized by abrupt-onset facial erythematous plaques with adherent dirt-like crusts. Histopathology revealed superficial dermal edema and dense perivascular neutrophilic infiltrates without vasculitis. Low-dose systemic corticosteroids (prednisone 20mg/day) achieved rapid resolution, underscoring their efficacy and safety in pregnancy. This case explores the potential pathogenesis of PASS and underscores the necessity for awareness among clinicians about PASS, contributing valuable insights into the diagnosis and management of this rare condition in pregnancy.
