[A case of sarcoidosis presenting with Heerfordt's syndrome, associated with hepatosplenomegaly, pleural effusion, and ascites].

A 30-year-old female developed symptoms consistent with Heerfordt's syndrome (complete type) and was effectively treated with steroid. However, she developed hepatosplenomegaly, bloody pleural effusion, and ascites one year after discontinuation of steroid therapy. The symptoms were considered to be due to sarcoidosis since serum ACE level, and ACE level and OKT4/8 ratio in pleural and peritoneal effusions were significantly elevated, and readministration of steroid normalized these changes. Bloody pleural and peritoneal effusions are very rare complications of sarcoidosis.
