Abstract

Federico Piñero, Sebastián Marciano and Adrián Carlos Gadano

We describe the case of a 69-year-old female who developed pancytopenia and acute hepatitis as a complication of intravesical BCG instillations for the treatment of bladder urothelial carcinoma. Liver and bone marrow biopsies revealed multinucleated giant epithelioid cells and non-caseating granulomas. Treatment with antituberculosis drugs achieved complete resolution. This case illustrates an infrequent but severe complication of intravesical BCG instillations, whichcan be successfully treated without steroids.
