Cutaneous metastasis in bladder cancer

Area of Science:

• Oncology
• Dermatology
• Urology

Background:

• Cutaneous manifestations of cancer are uncommon, particularly for bladder cancer.
• Iatrogenic implantation is a significant cause of secondary skin lesions in bladder cancer patients.
• Dermal metastases from urothelial carcinoma present diagnostic and therapeutic challenges due to their rarity and non-specific appearance.

Approach:

• The study presents a clinical case of a scalp lesion indicative of metastatic urothelial carcinoma.
• A comprehensive literature review was conducted to consolidate existing knowledge on this rare phenomenon.

Key Points:

• Scalp metastasis from urothelial carcinoma is an exceptionally rare presentation.
• The diagnosis can be challenging due to the lack of distinct dermatological patterns.
• Management strategies are not well-defined owing to limited case reports and poor prognosis.

Conclusions:

• Cutaneous involvement in bladder cancer, though rare, necessitates clinical vigilance.
• Further research is needed to establish clear diagnostic and management guidelines for metastatic urothelial carcinoma to the skin.
