Few cases of abdominal wall metastasis from a urothelial carcinoma were reported in the literature, and those were mostly attributed to iatrogenic implantation after laparoscopic surgery or a percutaneous nephrostomy. An 85-year-old man presented with an infraumbilical mass 6 months after transurethral resection of a bladder tumor (TURBt) for a T4 urinary bladder urothelial carcinoma. Abdominal sonog-raphy disclosed a 1.6 crri x 1.5 cm subcutaneous hypoechoic lesion. Wide excision of the mass was performed, and skin flaps were used for skin coverage. A combination of the patient's clinical history, tumor morphology, and immunostaining results were compatible with the pathologic characteristic of his previous bladder urothelial carcinoma. We present this rare case of solitary abdominal wall mass metastasis from a urothelial carcinoma of the urinary bladder.
