Abdominal subcutaneous metastasis from esophageal squamous cell carcinoma

Subcutaneous metastasis from esophageal carcinoma is rare, but skin tumors should be considered metastatic lesions in patients with a history of malignancy. We report a 75-year-old man with an unusual subcutaneous metastasis of esophageal carcinoma. The patient was diagnosed with esophageal squamous cell carcinoma and had been treated nine months earlier with neoadjuvant, concurrent chemo-radiotherapy followed by surgery. He later presented with a painless soft tissue mass on the right lower abdominal wall and subsequently a tender lump of skull metastasis. Histopathology and clinical imaging studies confirmed that these subcutaneous tumors were metastatic lesions, and he received chemotherapy and palliative radiotherapy. Uncommon esophageal carcinoma metastasis to skin and skull is discussed.
