Cutaneous Metastasis of Urothelial Tumors: A Rare but Critical Case Study

Introduction: Cutaneous metastases from urothelial tumors are extremely rare, often occurring due to iatrogenic tumor implantation. This article explores a compelling case of a 75-year-old patient who developed a parietal swelling at the site of a lumbotomy scar three years post-nephroureterectomy. Through this case, we examine the clinical significance, diagnostic challenges, and prognosis of such rare occurrences.

Case Summary and Findings

• A 75-year-old male patient, with no significant medical history, initially presented with total hematuria.
• Imaging confirmed a tumoral process in the upper right kidney, leading to nephroureterectomy with bladder collarette removal.
• Three years post-surgery, a 7 cm parietal swelling developed at the lumbotomy scar site, confirmed histologically as urothelial carcinoma metastasis.
• The tumor recurred aggressively within six months, growing to 25 cm and becoming unresectable, necessitating palliative chemotherapy.

Clinical Implications and Prognosis

• Cutaneous metastases of urinary tumors are exceptionally rare.
• Usual metastatic sites include lymph nodes, bones, liver, and lungs.
• The mechanisms of dissemination include direct invasion, surgical site implantation, and hematogenous or lymphatic spread.
• Prognosis remains poor, with a survival rate of less than six months post-diagnosis of cutaneous metastasis.

Integration of External Medical Sources: The American Urological Association (AUA) emphasizes the importance of early detection and management of urothelial carcinoma, particularly in high-risk patients.
