Gastrointestinal Stromal Cell Tumor (GIST) Presenting as an\nAbdomino-pelvic Tumor

Background: Gastrointestinal stromal tumors (GIST) are rare mesenchymal\ntumors that may mimic ovarian tumor on presurgical testing. These\ntumors are usually asymptomatic, often discovered accidentally during\nendoscopic or radiologic examinations,. Case Presentations: In first\ncase a 50 years old woman presented with irregular bleeding per\nvaginum, intermittent right lower abdominal pain and urinary frequency\nover the preceding 4 months. Physical examination and imaging studies\nrevealed a pelvic mass of 18-week-gestational size. An exploratory\nlaparotomy showed a huge fragile pelvic tumor, measuring 20 × 20\ncm, arising from the jejunum. Immunohistochemical staining confirmed\nthe presence of CD-117. In second case an 53-year-old, postmenopausal,\nwoman presented with abdominal fullness and constipation for the\npreceding 3-4 days. Physical examination and imaging studies revealed a\nhuge pelvic mass, suggestive of a cystic degenerated myoma. An\nexploratory laparotomy revealed a large tumor originating from the\nileum. Conclusion: Gynecologists should keep in mind the possibility of\nnon gynaecological tumors (GISTs) in the differential diagnosis in\npelvic tumors.
