Patient with Gianotti-Crosti Syndrome (GCS) presents with a distinctive self-limiting acral papular or papulovesicular eruption. Patient with GCS is associated with an underlying viral and bacterial illness. GCS is a self-limiting cutaneuous response to different infections. Its clinical differences are probably due to individual characteristics of each patient rather than the causative infections agents. GCS in patients infected with hepatitis A virus has not been reported previously in Korea. We report a case of 16-year-old girl who developed an erythematous papular eruption on her extremities a week after an epidemic of hepatitis A. The patient had the characteristics which resembled clinical and histopathologic findings of GCS. Hepatitis A virus RNA was detected by nested reverse transcription-polymerase chain reaction of tissue from lesion site of the patient. (Kor J Gastroenterol 2000;36:552 - 556)
