Primary squamous cell carcinoma of the urinary bladder presenting as an inguinal mass.

This report involves a rare case of a 74-year-old man who presented with a progressively increasing swelling in the right groin, which represented a squamous cell bladder carcinoma herniating into the right inguinal canal. The manuscript discusses the role of multimodality imaging in bladder carcinoma presenting as an inguinoscrotal hernia. The patient subsequently underwent treatment with a chemotherapy regimen consisting of 5-fluorouracil and mitomycin, which was extrapolated from squamous cell carcinoma of the anal canal, and responded well.
