Gastrointestinal stromal tumors are a small portion of gastrointestinal malignancies that usually present in the stomach. This is a case of a sixty-four-year-old male who presented with large gastrointestinal stromal tumors that had undergone cystic degeneration, and was initially thought to be a pancreatic pseudocyst due to radiographic and biochemical findings. The diagnosis was established after an endoscopic ultrasound was performed with fine needle aspiration showing histology and endoscopic findings consistent with a neoplasm. This is an interesting case due to the atypical presentation of the gastrointestinal stromal tumors.
