Abstract

Intravesical bacillus Calmette-Guérin (BCG) is used for urothelial carcinoma. Systemic side effects are rare and commonly include organ involvement but rarely include bone marrow. We describe a patient who had received intravesical BCG and presented shortly afterwards with constitutional symptoms. Initial work-up revealed pancytopenia and immune haemolysis. He was presumptively diagnosed with systemic BCG infection and secondary warm autoimmune haemolytic anaemia. Isoniazid, rifampin and ethambutol was started. The bone marrow biopsy revealed granulomas. Within 6 weeks of treatment, the patient's clinic and laboratory results were dramatically improved. A high level of suspicion is crucial for diagnosis and treatment.
