title: Infrequent patterns of upper gastrointestinal tract malignancy.
abstract: The skin and the upper gastrointestinal tract are frequent sites of malignant tumors. However, cutaneous metastasis from primary gastrointestinal tract lesions remains a relative rarity. Similarly rare is spread of primary skin cancer (nonmelanomatous) to upper gastrointestinal tract. This paper presents an unusual example of primary esophageal carcinoma with synchronous skin and bone metastases and a case of squamous cell carcinoma of the stomach, possibly due to spread from a remote squamous cell carcinoma of the skin.
