• Her EGD showed: – Normal esophagus. Atrophic mucosa in

antrum. Normal dudodenum.– Negative Helicobacter pylori.– Pathology: chronic mildly active gastritis

with extensive metaplasia.

Hospital course and Follow-up

• The patient had an exploratory laparotomy– Evidence of miliary disease – Bilateral oopherectomy and hysterectomy– Pathology: Non-caseating granulomas. (AFB -)

• Tuberculosis versus Sarcoidosis

Treatment of Tuberculosis of the Genital Tract

• Similar to treatment for TB at extrapulmonary sites.

• A 6-mo regimen

– 2 months of isoniazid, rifampin, and pyrazinamide

– 4 months of isoniazid and rifampin – Ethambutol should be used until the results of

drug susceptibility studies are available, unless there is little possibility of drug resistance
