ABSTRACT
Rationale: Genitourinary tuberculosis can develop during the disease course of disseminated disease and the distinctive histological finding is epithelioid granuloma with or without caseation and accompanied Langhans-type giant cells. Barely, the lesion is only restricted to kidney involving both glomerular and extraglomerular compartment. Association with immune complex-mediated glomerulonephritis has been sparsely reported in the literature. Patient concern: A 42-year-old non-diabetic, non-hypertensive male presented with generalized body swelling and frothing of urine for 3 months. Diagnosis: Membranous nephropathy with tuberculous interstitial nephritis. Intervention: Anti-tuberculous therapy for extrapulmonary tuberculosis was administered along with low dose corticosteroid. Outcomes: Reduction of proteinuria was achieved at one month follow-up visit. Lessons: Tuberculosis should be considered as a potentially treatable cause of secondary membranous nephropathy as pharmacotherapy greatly helps improve the outcome.
