Abstract A 37-year old female, 6 months post renal transplant with no other co-morbid features presented with haematuria since one week. Cystoscopy was planned and a therapeutic procedure of transurethral resection is based on clinical impression of papillary transitional cell carcinoma (TCC). Histopathology showed nephrogenic adenoma. Antibiotic course was given for three weeks. Cystoscopy and ultrasound surveillance showed no evidence of recurrence over the last 18 months. Here is a rare case of nephrogenic adenoma occurred after transplant, which was initially confused for bladder malignancy. Although nephrogenic adenomas may resemble certain types of urologic malignancies, their histology is distinctive and varies little from lesion to lesion, so that once an entity is considered; an accurate pathologic diagnosis is rarely a problem. This case report discusses about presentation and management of a case of nephrogenic adenoma features that differentiate it from bladder malignancy.
