Anal metastasis from carcinoma of the lung: report of a case.
We report herein the case of a 75-year-old man who developed anal canal metastasis from squamous cell carcinoma of the lung. Initially, he underwent a right middle and lower lobectomy combined with left atrial wall resection under cardiopulmonary bypass. He presented 3 months later with an anal polyp which had prolapsed and bled, for which he underwent a transanal polypectomy. Histologically, the polyp was classified as squamous cell carcinoma and considered to be a metastasis from the primary lung cancer. He is presently well with no signs of recurrence 9 months after his initial operation. To our knowledge, there has been no other case of anal metastasis from lung cancer ever reported.
