Case Report Pseudotumoral Malacoplakia of the Bladder

Malacoplakia is a rare inflammatory condition most often affecting the genitourinary system. We report the case of a 24-year-old man who presented with gross hematuria, nocturia, frequency, dysuria and considerable weight loss during the preceding three months. Digital rectal examination showed a solid pelvic mass. Ultrasonography and computed tomography showed calyceal dilatation on the right side and a solid bladder mass 10 cm in diameter suspicious of bladder cancer. Transurethral resection of the tumor was incomplete, due to the large volume of the bladder mass. Histological examination of the resected specimen revealed malacoplakia of the bladder. The patient was treated with fluoroquinolone and vitamin C. Follow-up at 3 months showed marked regression of the bladder mass and complete resolution of the calyceal dilatation
