A Case of Esophageal Adenocarcinoma Metastasized to the Scalp

ABSTRACT

Cutaneous metastases from internal malignancies are, occurring in 0.5% to 9% of cases. Lung, breast, and colorectal cancers are common primary tumors that metastasize to the skin; cutaneous metastasis usually occurs on the chest wall and abdomen as asymptomatic nodular patterns. Esophageal cancer is not nearly as common as breast, lung, and colorectal cancers, and esophageal cancer rarely metastasizes to the skin. Cutaneous metastasis of esophageal cancer is rare and metastasis to the scalp is extremely rare. Only a few cases of cutaneous metastases of esophageal cancer have been reported in Korea. Most of the cases involved cutaneous metastases arising from esophageal squamous cell carcinoma; however, there have been several reports describing cutaneous metastases from esophageal adenocarcinomas. Herein, we describe a case of metastatic skin cancer that originated from esophageal adenocarcinoma.
