Introduction: Retroperitoneal paraganglioma (RPGL) is a rare clinical tumor derived from the retroperitoneal sympathetic paraganglion tissue. Since RPGLs are locate deeply and have no specific symptoms and imaging manifestations at the early stage, which easily causes missed diagnosis or misdiagnosis. In addition, reports on totally laparoscopic resection of RPGLs are scarce due to their close proximity to large vessels, giant size, uncertain location, and unknown malignant status.Case Presentation: We present here the case of totally laparoscopic resection of a 6.4 × 5.4 cm RPGL that was discovered during a workup for discomfort and upper abdominal pain in a 68-year-old female patient, mimicking a gastrointestinal stromal tumor (GIST) of the duodenum, Which was confirmed as a RPGL based on the histopathological and immunohistochemical findings.Conclusions: RPGL is a rare tumor, and the transperitoneal laparoscopic approach for the RPGL is a safe, applicable method with less trauma and quick recovery, which is worth clinical popularizing and application. Moreover, the survival prognosis of RPGL patients are related to metastasis, and lifelong follow-up should be emphasized.

A 76-year-old man presented to our hospital with abdominal distention and loss of appetite. The 10% of weight lost relative to this patient in 1 month. Abdominal computed tomography and magnetic resonance imaging revealed a giant mass, with a major axis of 23 cm, containing solid components, not involving the upper abdominal organs. Esophagogastroduodenoscopy showed extramural compression from the middle gastric body to the antrum, as well as a normal mucosal surface. These findings were suggestive of a gastrointestinal stromal tumor attached to the anterior wall of the stomach without metastasis or invasion. Partial gastrectomy was performed for tumor resection, and the patient was subsequently treated with adjuvant imatinib. We report a rare case of a large extramural gastrointestinal stromal tumor of the stomach that was larger than 20 cm in diameter and present a pertinent literature review.
