Abstract

Squamous cell carcinoma arising from a suprapubic cystostomy tract (SCC-SCT) is a relatively rare bladder malignancy. We present a case of highly differentiated SCC-SCT involving the bladder in a 61-year-old patient with transplanted kidney. Abdominal magnetic resonance imaging revealed an anomalous mass (8 cm × 6 cm × 5 cm) surrounding the suprapubic cystostomy and a space-occupying lesion in the bladder. The pathology report revealed highly differentiated SCC. The patient received radiation therapy after he refused aggressive surgical management in 2012. There was no evidence of metastasis at his latest follow-up in early 2015.

Keywords: Squamous cell carcinoma; bladder malignancy; suprapubic cystostomy.

MRI (T2WI phase) findings before radiotherapy. An irregularly-shaped mass (black arrow) surrounding the suprapubic catheter (white arrow) was detected. A relatively clear boundary between the invasive bladder mass and cystostomy tract tissue could be seen.

Disordered squamous epithelial cells and typical highly differentiated squamous cells were seen in the pathology slides of the tumor biopsy (hematoxylin and eosin staining, ×200), which verified the diagnosis of SCC.

MRI (T2WI phase) findings after performing 6-month radiotherapy. There was no apparent mass around the suprapubic catheter (white arrow). The bladder wall was intact and smooth.

MRI (T2WI phase) findings after performing 30-month radiotherapy. No abnormal mass around the suprapubic catheter (white arrow) was detected.
