title: Massive zosteriform cutaneous metastasis from rectal carcinoma.
abstract: A 44-year-old man presented with a large and rapidly growing skin lesion approximately six months after resection of a rectal carcinoma. The lesion measured 40 cm in size, extended from the suprapubic area to the proximal half of the left groin, and showed a particular zosteriform aspect. Biopsy confirmed a metastatic skin adenocarcinoma. Cutaneous metastases from rectal cancer are very uncommon. Their gross appearance is not distinctive, although the skin tumors are usually solid, small (less than 5 cm) and painless nodules or papules. Early biopsies for suspicious skin lesions are needed in patients with a history of colorectal cancer.
