Primary gastric tuberculosis: a case report and literature review

Gastric tuberculosis is a rare entity; it usually occurs secondary to another lesion(s), mainly in the lungs. Only a few cases of primary gastric tuberculosis have been reported in the literature. Most commonly, gastric tuberculosis lesion(s) is located in the lesser curvature of the antrum and prepylorus, so the clinical picture is similar to that of peptic ulcer, in addition to the constitutional symptoms seen in tuberculosis in general. We report a case of a young man presented with abdominal pain acute gastric outlet obstruction due to a large mass in the lesser curvature of the antrum and the pylorus. The histological examination revealed caseating granuloma with the presence of acid-fast bacilli. Partial gastrectomy with Bilroth II reconstruction was performed and the patient was put on antituberculosis medications. There was no evidence of the tuberculous lesion anywhere else. Patient's follow-up observation in the clinic was uneventful.
