[Pulmonary and gastric sarcoidosis. Report of one case].

We report a 66 year-old woman with a history of pulmonary sarcoidosis, diagnosed with a lung biopsy in 1993 and treated with prednisone for 2 years. She presented at our institution in 1999 with a stage IV disease and important functional and clinical impairment. A bronchial biopsy disclosed non caseating granulomas. Tuberculosis was intensively studied and persistently negative. Due to frequent nausea and vomiting an endoscopic gastric biopsy was performed which revealed non caseating granulomas involving the gastric mucosa. There was no evidence of Helicobacter pylori and stains for fungi and acid-fast bacilli were negative. Treatment with prednisone relieved digestive symptoms, although a control biopsy of the gastric mucosa revealed persistence of non caseating granulomas. Both lung stage IV and gastric sarcoidosis are uncommon forms of the disease.
