Benign gastric tumors are infrequent, being leiomiomas and lipomas the more common among them. Recently a new pathological entity has been described denominated Gastro Intestinal Stromal Tumors (GIST) which originates from the Cajal cells. Treatment is mostly surgical and they are sensible to chemotherapy. Clinical manifestation varies, appearing generally with fullness, bleeding or dyspepsia. Diagnostic methods are multiple; ecoendoscopy is of great importance to determine treatment, whether endoscopic or surgical resection. We present a 18 years old female patient, without previous pathology, who presented with general malaise, adynamia, mucous cutaneous pallor, dizziness and migraine. Self-medicated with NSAID`s, presenting later hematemesis and melena. At physical examination: pallor, tachycardia, slow capillary filling, abdomen distended and painful. Laboratory: anemia, the rest without alterations. Abdominal ultrasound: Epigastric tumor. Gastroscopy: submucosal tumor with active bleeding, argon plasma coagulation was applied. Eco Endoscopy concluded a giant leiomioma. The immunohistochemistry report was positive for vimentine and CD117 (CKIT), compatible with a gastrointestinal stromal tumor of the epithelioid kind. A subtotal gastrectomy was performed. GIST can have a benign or potentially malignant behavior with relapse or metastasis.
