Abstract

Gastrointestinal stromal tumors arise from mesenchymal cells of gastrointestinal tract and are seen rarely. In fewer than 5% of cases they arise from outside of gastrointestinal tract, they originate primarily from mesentery, omentum and peritoneum. These are called extragastrointestinal tumors and they share the histological features with their gastrointestinal counterparts. A 57-year-old male patient was admitted to our hospital with complaint of abdominal pain. In his physical examination, an abdominal mass was detected in his left lower quadrant. Radiological examinations revealed an abdominal mass measuring 13x9 cm in diameter, adjacent to the bladder. Laparotomy demonstrated a lobulating mass of about 13x10 cm in diameter, originating from mesenterium of the sigmoid colon. En-bloc resection of the tumor with sigmoidectomy and end-to-end anastomosis was performed. Histopathology of the specimen showed that the tumor demonstrating high cellularity composed of spindle-shaped tumor cells. There was no continuity of tumor within the sigmoid colon and the margins of specimen were tumor-negative. Immunohistochemically, the tumor was positive for c-kit (CD 117). The tumor was diagnosed as a gastrointestinal stromal tumor originating from mesenterium of the sigmoid colon. A gastrointestinal stromal tumor of the sigmoid mesenterium is a rare entity. Surgical resection is the treatment of choice for these tumors, which usually have a poor prognosis.

Özet

Gastrointestinal sistemin stromal tümörleri gastrointestinal sistemin mezenkimal hücrelerinden kaynaklanan ve nadir görülen tümörlerdir. Olguların %5'inden daha azında gastrointestinal sistem dışından kaynaklanır, esas olarak mezenter, omentum ve peritondan kaynaklanır. Bunlar ekstra gastrointestinal stromal tümörler olarak adlandırılır ve gastrointestinal sistemde görülenlerle aynı histolojik özellikleri paylaşırlar. Elli yedi yaşında erkek hasta hastanemize karın ağrısı nedeniyle başvurdu. Yapılan muayenesinde sol alt kadranda kitle tespit edildi. Yapılan radyolojik incelemelerde mesane komşuluğunda 13x9 cm boyutlarında kitle saptandı. Hastanın ameliyatında sigmoid mezenterinden kaynaklanan 13x10 cm'lik lobüle kontürlü kitle tespit edildi. Tümör sigmoid kolon ile beraber rezeke edildi ve uçuca anastomoz yapıldı. Spesmenin histopatolojisinde tümörün selülaritesi fazla ve iğsi hücrelerden oluşuyordu. Tümörün sigmoid kolonla ilişkisi yoktu ve spesmenin sınırlarında tümöre rastlanmadı. İmmünohistokimyasal incelemede tümör C-kit (CD117) pozitif saptandı. Patoloji sonucu sigmoid mezenterinden köken alan gastrointestinal stromal tümör olarak saptandı. Primer tedavileri cerrahi olarak total çıkartılmasıdır. Sıklıkla kötü prognoza sahiptirler. Bu olgularda kitlenin tamamen çıkarılması önemlidir, nadir görülmelerine rağmen atipik yerleşimli karın içi tümörlerde akla gelmelidirler.
