Due to the extreme rarity of cutaneous metastases from ESCC, there are only limited data in the literature regarding their incidence. Fereidooni and colleagues reported a solid facial skin metastasis of EACC [
11]. Two additional cases have been published discussing solitary metastases on a digit from an unusual variant of ESCC, the basaloid squamous cell carcinoma [
12,
13]. Schoenlaub and colleagues reviewed the clinical findings and overall survival of 200 patients with cutaneous metastases of various cancers. The incidence of cutaneous metastases from EACC was 2 out of the 200 cases studied [
6]. The cancers most frequently causing cutaneous metastases were breast cancers (
n = 64), pulmonary cancers (
n = 36) and melanomas (
n = 31) [
6]. Reingold reported clinical and necropsy findings of 32 cases out of 2,300 internal carcinomas. The most common primary site was the lungs (50%). The esophagus was the primary tumor site in just one case and this was an adenocarcinoma. The most common sites of skin metastases were on the chest and abdomen [
14]. Lookingbill et al reviewed 420 patients with cutaneous metastases from melanoma and carcinoma [
9]. In this study, tumor registry data from 7,608 patients was evaluated; 4,020 of these patients had metastatic disease and 420 (10.4%) had cutaneous metastases. The most common primary tumors causing cutaneous metastases were melanoma (
n = 77) and breast cancer (
n = 212). The esophagus was the primary site in only three cases, spreading mainly to the chest and abdomen [
9]. Tharakaram described five cases of skin metastases from ESCC in male patients [
15].
