Skin metastasis from sigmoid colon cancer.
Skin metastases from visceral cancers are rare and the reported incidence from all visceral cancers is 1.4% to 10%. Skin metastases from colorectal cancers account for only 5% of metastatic skin cancers, among which scalp metastases are very rare. We describe a 53-year-old man with scalp metastasis derived from sigmoid colon cancer that was diagnosed and surgically resected in 2005. Metastatic lung tumors that developed thereafter were surgically resected and then chemotherapy was administered. However, metastatic brain tumors occurred in 2008, and these were treated by gamma-knife radiosurgery. Around the same time, a raised lesion that appeared on the scalp was diagnosed as skin metastasis and treated with best supportive care. Thereafter, the brain metastases continued to spread, and the patient died in October 2008.
