RADYOLOJİK VE PATOLOJİK TANISI KONAN SAFRA KESESİ FİBROMU: OLGU SUNUMU VE LİTERATÜR TARAMASI Gallbladder Fibroma Diagnosed With Radiology and Pathology: A Case Report and Literature Review

OZET Fibromlar, vucudun herhangi bir yerinde ozelliklede diz ve parmaklarda gorulen, yavas buyuyen, agrisiz ve sert kitlelerdir. Safra kesesi fibromusi nadir bir tumordur ve literaturde sadece birkac adet olgu sunumu olarak yer almaktadir. Biz burada ultrasonografi ve manyetik rezonans kolanjiyografide preoperatif olarak safra kesesi polibi tanisi konan 49 yasinda bir kadin hastayi sunmayi amacladik. Kolesistektomi spesmeninin makroskopik incelemesinde kese hidropik gorunumde olup kesitlerinde boyun kisminda polipoid bir kitle izlendi. Makroskobik olarak nodul, kollajenoz stromada oval yuvarlak sekilli hucrelerden olusuyordu. Stromal hucreler Vimentin ile pozitif immunreaktivite gosterdi; Desmin, S-100, SMA ve CD34 negatifti. Lezyonu safra kesesi fibromusi olarak teshis ettik. Anahtar kelimeler: Fibrom; Safra kesesi; Ultrasonografi. ABSTRACT Fibromas are slowly growing, painless and firm masses which can be seen everywhere in the body, especially in knees and fingers. Gallbladder fibromas are rare tumors and only a few cases are reported in the literature as case reports. In this study we present a 49-year old woman patient who takes gallbladder polyp diagnosis with ultrasonographic and magnetic resonance cholangiographic examination preoperatively. In macroscopic examination of the gallbladder specimen, it had a hydrophic appearance and when gallbladder lumen was opened, a polypoid mass was seen in the neck region. Microscopically a nodule was observed which consisted of oval to round shaped cells in collagenous stroma. Stromal cells showed positive immunoreactivity with vimentin. Desmin, S-100, SMA and CD34 were negative. The lesion was identified as gallbladder fibroma. Keywords: Fibroma; Gallbladder; Ultrasonography.
