Abstract

Ciliated foregut cyst of gallbladder is a very rare benign cystic lesion. A 39-year-old woman was referred to our hospital after abdominal ultrasonography revealed a cystic lesion of gallbladder. On abdominal ultrasonography and computed tomography, a unilocular cystic lesion was found at right upper quadrant with attachment to the gallbladder neck. The gallbladder with cystic lesion was resected through laparoscopic cholecystectomy. The cystic lesion revealed a unilocular cyst with ciliated cuboidal or columnar epithelium and abundant goblet cells. Pathologic examination is essential to distinguish from other cystic lesions of the gallbladder and avoid unnecessary additional treatment. In the current case report, we presented the clinico-pathologic findings of the ciliated foregut cyst of the gallbladder and review of literature.

  Fig. 3 Microphotographs of the resected specimen. (A) The cystic lining cells consist of the ciliated cuboidal (left) or columnar epithelium (right) and abundant goblet cells (H-E stain, ×400). (B) Dense smooth muscle layer is present in the subepithelial layer (H-E stain, ×200). (C) Subepithelial layer also contains the fibroelastic connective tissue (H-E stain, ×200). (D) Some eosinophils, lymphocytes and adipocytes are identified in the fibroelastic connective tissue (H-E stain, ×400).
