[Tubular adenoma of the gallbladder with squamous metaplasia].

Adenomas of the gallbladder are rare tumors. They may be papillar or tubular. Tubular adenoma appears in middle aged and older patients, although it may develop even in children. This is a case report of forty-year old woman in whom a polypoid lesion was discovered in the gallbladder during regular ultrasonographic control after the liver surgery for hemangioma. The gallbladder was removed during an open surgery. A polypoid tumour of 20x7x5mm in size on wide pedicle was found in the gallbladder. Histology showed tubular adenoma with mild epithelial dysplasia in some places and with antral and squamous metaplasia. The recovery was uneventful.
