An endemic dermatitis of unknown etiology occurred in June and July of 1981 among farmers working in the paddy fields of Ayai and Itabara in Izumiotsu city, the southern district of Osaka Prefecture. Two patients living in Ayazono (Takaishi city) and other 3 patients living in Itabara were found. The dermatitis was characterized by erythemato-papulovesicular eruption accompanied by severe itching and localized on hands and lower legs exposed to paddy field water. Symptoms of the dermatitis were similar to the cercarial dermatitis which has been known to be caused by an invasion of cercaria larvae of bird schistosome into the human skin. A search for the snails collected from the paddy field of Ayai revealed that Austropeplea ollula (Himemonoaragai) was infected with the furcocercous cercaria belonging to the genus Trichobilharzia which has been reported as a cause of the paddy field dermatitis in Japan. The species of this cercaria has never been identified. The results suggest that the dermatitis occurring in Ayai was caused by an accidental invasion of these cercariae. The etiology of the dermatitis in Itabara was still uncertain, but the symptoms of patients and wide distribution of A. ollula in the endemic area were suggestive of a similar cause.
