title: Squamous cell carcinoma of gallbladder--report of two cases and review of literature.
abstract: Two cases of a well-differentiated keratinizing squamous cell carcinoma of the gallbladder were reported. Pathologic analysis of this rare neoplasm was made in conjunction with cases of the gallbladder carcinoma of a squamous cell variety reported in literatures. The squamous cell carcinoma is characterized by a well-localized growth and a rarity or lack of metastasis. These characteristics make a good contract with an adenosquamous carcinoma of the gallbladder which usually infiltrates rather extensively and metastasizes widely. Thus the adenosquamous carcinoma should be sequestered from group of squamous cell carcinoma. Radical operative procedures may well be encouraged on selected cases of squamous cell carcinoma.
