A gastrointestinal stromal tumor of stomach presenting with an intratumoral abscess: A case report.

Background: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors in the gastrointestinal tract, GISTs of the stomach presenting as an intratumoral abscess are extremely rare, which necessitates emergency surgery, we report a case of a stomach GIST developing an intratumoral abscess, in whom emergency surgery was performed.

Methods: A 68-year-old man presented with severe abdominal pain and a fever. Laboratory data showed an elevated white blood cell count and C-reactive protein level. Computed to mography scan showed a 15 × 10 cm cystic mass adjacent to greater curvature of the stomach, which contained air. Emergency laparotomy revealed A giant cystic gastric mass was observed. Sleeve gastrectomy were performed. Immunohistochemically, the tumor was diagnosed as a Gastric high risk GIST,and imatinib mesylate was initiated, The patient had an uneventful postoperative course and remains well.

Conclusions: Such rare cases can be diagnosed and treated properly with careful clinical evaluation, surgical resection and adjuvant chemotherapy with imatinib mesylate is still the mainstay and most effective treatment for GISTs to date.
