Abstract

Herein we report a case of a squamous cell carcinoma of a well-healed suprapubic cystostomy tract scar involving the bladder mucosa in a 56-year-old man. He presented with a spontaneous suprapubic urinary leak from a suprapubic cystostomy tract scar. He had a history of urethral stricture and failed urethroplasty. Preoperative cystoscopy suggested a bladder mass. Transurethral biopsy of the bladder mass revealed a squamous cell carcinoma confined to the suprapubic cystostomy tract involving the bladder mucosa. The patient died 6 months after the start of radiation therapy after lung metastasis and pneumonia.

  FIG. 1 Computed tomography of the abdomen showing the catheter in the bladder below a tumor mass encasing the catheter as it passes through the abdominal wall.

  FIG. 2 The pathologic features of the tumor mass (H&E, ×200). The microphotograph showed an invasive squamous cell carcinoma with well-differentiated mature squamous cells and abundant keratin pearls and occasional well-developed intercellular bridges.
