Pankreas başı tümörü gibi davranan duodenal gastrointestinal stromal tümör

Bu yazı ile sadece ekstramural büyüme gösteren ve pankreas başı tümörü izlenimi veren duodenal gastrointestinal stromal tümörü olan (GIST) bir olgunun sunulması amaçlanmıştır. Ellialtı yaşındaki kadın hastada preoperatif dönemde tomografi ile batın orta kısmında 12x7x5 cm.lik heterojen bir kitle bulundu. Endoskopik muayenede duodenal lümen içinde mukozada bir anormallik saptanmadı. Ameliyatta pankreas başına uyan bölgede sert bir tümör saptandı. Peritoneal yayılım veya metastaz yoktu. İnce iğne aspirasyon biopsisinde tümör GIST olarak bildirildi. İatrojenik duodenal yaralanma oluşması nedeniyle hastaya pilor korucu pankreatikoduodektomi yapıldı. Histolojik inceleme ile tümöre pankreas dokusuna invaze duodenal GIST tanısı kondu. Bu şekilde ekstramural büyüme gösteren ve pankreas başı tümörü izlenimi veren tümör olgusu çok nadirdir.

A gastrointestinal stromal tumor of the duodenum mimicking a pancreatic head tum

We aimed to report a case with a gastrointestinal stromal tumor (GIST) of the duodenum that showed only extramural growth, mimicking a pancreatic head tumor. A 56-year-old woman. Computed tomography revealed a heterogen mass, 12x7x5 cm in diameter, in mid abdominal region preoperatively. Endoscopic examination showed no specific mucosal abnormalities in the duodenal lumen. A hard mass was detected intraoperatively in the pancreatic head region, and neither peritoneal dissemination nor metastasis was detected. The tumor was diagnosed peroperatively as a GIST in FNA biopsy, and the patient underwent pylorus-preserving pancreaticoduodenectomy because of iatrogenic duodenal injury. This neoplasm was finally diagnosed histologically as a duodenal GIST with the pancreatic tissue invasion. This is a rare case of a duodenal GIST with exclusively extramural growth mimicking a pancreatic head tumor.
