A Case of Sarcoidosis Manifesting Liver Involvement after Disappearance of Muscle Lesion Hirohisa Ichikawa1), Mikio Kataoka2), Yoshiko Ogata1), Masakazu Ohmori1), Junichi Hiramatsu1), Yasusi Tanimoto1), Arihiko Kanehiro1), Yasunari Nakata2), Mitsune Tanimoto1) ABSTRACT z We report a case of a 42-year-old man who had bilateral hilar lymphadenopathy and small nodular shadows in the left upper lung field detected by a health check-up at the age of 35. He was diagnosed as having sarcoidosis by TBLB. He had a nodule on his right thigh and was diagnosed as having muscular sarcoidosis by muscle biopsy. We carefully followed-up the disease course without any treatment, and the tumor finally disappeared. At the age of 42, he suffered from back pain and went to a hospital. Because his abdominal CT revealed an irregular surface of the liver and multiple hypodense lesions in the liver and spleen, he was admitted to our hospital for further examinations. A laparoscopy revealed white plaque covering the liver. Biopsy specimens showed non-caseating granulomas. He was diagnosed as having liver sarcoidosis and treated with prednisolone (40mg/day). He died from a sudden accident after this. Here, we report a valuable case in which nodular muscular sarcoidosis and hepatic sarcoi dosis were seen at different times. keywords; Nodular muscular sarcoidosis, Hepatic sarcoidosis, Laparoscopic liver biopsy [JJSOG 2004; 24: 71-76] TEL: 086-235-7227 FAX: 086-232-8226 E-mail: hirohisa@cc.okayama-u.ac.jp Okayama University Medical School 1) Hematology, Oncology and Respiratory Medicine 2) Faculty of Health Sciences
