Cutaneous metastatic squamous-cell carcinoma in zosteriform distribution.

A renal transplant patient on immunosuppressives with a history of multiple premalignant and malignant skin tumors developed cutaneous metastatic squamous-cell carcinoma in a typical zosteriform distribution on the right arm and chest. This distribution of a squamous-cell carcinoma is unique to the English literature and serves to emphasize the necessity for frequent follow-up and aggressive treatment in this high-risk population.
