Retroperitoneal Silyalı Foregut Kisti: Nadir Bir MalformasyonAsuman Kilitci1, Haldun Umudum2, Osman Memiş31Ahi Evran Üniversitesi Eğitim Ve Araştırma Hastanesi, Patoloji Bölümü, Kırşehir2Ufuk Üniversitesi Tıp Fakültesi, Patoloji Bölümü, Ankara 3Ahi Evran Üniversitesi Eğitim Ve Araştırma Hastanesi, Genel Cerrahi Bölümü, Kırşehir Foregut kisti (FC), silyalı psödostratifiye kolumnar epitel, subepitelyal bağ dokusu, düz kas tabakası ve dış fibröz kapsül olmak üzere dört tabakadan oluşan nadir, benign, soliter bir kisttir. FC'ler bronkojenik, enterogastrik ve diferansiye olmayan olarak sınıflandırılır. Friedreich lezyonu ilk kez 1857'de tanımlamış ve doğuştan kökenini öngörmüştür. Retroperitoneal bölgede ortaya çıkan ve diğer retroperitoneal kistik kitle lezyonlarından ayrılması zor bir FC sunuyoruz. 27 yaşındaki bayan, yan ağrısı ile başvurdu. Karın BT'sinde, mide posterioru, sol böbrek üst kutbu ve pankreas arasına yerleşmiş yaklaşık 7.8 cm çapında kistik bir lezyon izlendi. Total kistektomi yapıldı. Retroperitoneal Ciliated Foregut Cyst: A Rare MalformationAsuman Kilitci1, Haldun Umudum2, Osman Memiş31Department Of Pathology, Ahi Evran University Education And Research Hospital, Kırşehir, Turkey2Department Of Pathology, Ufuk University Medical Faculty, Ankara, Turkey 3Department Of General Surgery, Ahi Evran University Education And Research Hospital, Kırşehir, Turkey Foregut cyst (FC) is an uncommon, benign, solitary cyst consisting of four layers; ciliated pseudostratified columnar epithelium, subepithelial connective tissue, a smooth muscle layer, and an outer fibrous capsule. FCs are classified as bronchogenic, enterogastric or undifferentiated. Friedreich first described the lesion in 1857 and predicted its congenital origin. We present a FC that arised in the retroperitoneum and was difficult to separate from other retroperitoneal cystic mass lesions. A 27-year-old female presented with flank pain. Abdominal CT revealed a cystic lesion, measuring approximately 7.8 cm in diameter, located near the posterior stomach, superior pole of left kidney and pancreas. Total cystectomy was performed. Macroscopic examination revealed a 7.8x6 cm unilocular cyst enclosed by a thin capsule, which contained viscous, yellowish fluid. There was no solid component in the lesion. The surgeon confirmed no continuity of the cyst into the surrounding organs. Microscopy demonstrated the cyst to consist of four layers. In focal areas, seromucous glands were seen in the wall. There was no evidence of malignancy. By this findings, this case was diagnosed as retroperitoneal ciliated foregut cyst. FC located in the abdomen or retroperitoneum is extremely rare and few cases have been described in English literature. Intraabdominal and retroperitoneal locations have been explained by the presence of pleuroperitoneal canals in the early embryonic stage. FC should be considered in the differential diagnosis of retroperitoneal cystic masses includes lymphangiomas, cytic pancreatic tumors, pseudocysts, and hematomas.
