Abstract

Giant cell tumor of tendon sheath(GCTTS) is a benign mesenchymal lesion composed of cytologically bland mononuclear cells admixed with multinucleated giant cells. Our report describes the clinical and pathologic features of a 36-year-old female's tumor with a two years history over the lateral side of the left little finger, Especially, we could observe the characteristic thre types of cells in an electromicroscopic study, histiocyte-like cells, fibroblast-like cells and multinucleated giant cells. In lmmunohistochemical studies, we demonstrated that the tumor cells of GCTTS exhibit a phenotype consistent with histiocyte differentiated to Langerhan's cell.
