The Synchronous Occurrence of Neuroendocrine Tumor and Gastrointestinal Stromal Tumor (GIST) at Gastric Site

Gastrointestinal stromal tumors (GIST) are the most frequent sarcomas in the gastrointestinal tract. They affect all segments of the digestive tract. The incidental occurrence of GIST and other primary tumors has not been well described in literature. We describe a case of a 73 year old patient who underwent surgery for gastric GIST with an incidental pathologic diagnosis of a gastric neuroendocrine tumor. The occasional finding of this association underlines the importance of a carefully pathological diagnosis for its identification. In literature there is no evidence of concomitant neuroendocrine tumor and gastrointestinal stromal tumor (GIST) at gastric site.
