—Serosal involvement in sarcoidosis is infrequent, being a peritoneal affectation even more rarely.1-3 In 1981, we reported a case of peritoneal sarcoidosis as a unique manifestation of the disease.4 Recently, we had the opportunity to treat a second case with nearly identical manifestations.
Report of a Case.
—A 45-day-long history of painful abdominal distention, anorexia, and occasional vomiting was recorded in a 57-year-old afebrile man. Physical examination revealed tense ascites, right pleural effusion, and tender hepatomegaly. Neither spleen nor enlarged lymph nodes were present.Blood and urine analysis were normal, except for elevation of erythrocyte sedimentation rate (83 and 115 mm/h, respectively). Ascitic fluid examination revealed a high protein level (51 g/L [5.1 g/dL]) and a leukocyte count of 3×109/L (3000/mm3) (0.85 [85%] lymphocytes).Results of pleural and peritoneal fluid examinations were very similar; a pleural biopsy specimen was normal.
