Abstracto
The authors report a case of a male patient in his forties with progressive abdominal pain associated with weight loss, dyspnea, and edema of the inferior limbs, culminating in a surgical acute abdomen. A segmental enterectomy containing a lesion of about 10 cm in diameter was performed. It was later confirmed, by means of immuno-histochemistry, as being a Gastrointestinal Stromal Tumor of high biological aggressiveness. Etiology, diagnosis, classification, prognosis and therapeutic with Imatinib Mesylate-STI-571 (Glivec®-Novartis) are hence discussed.
