Giant cell tumor of soft tissues of low malignant potential: A rare diagnosis on fine needle aspiration cytology

Maithili M Kulkarni et al. J Cytol. 2016 Apr-Jun.

Abstract

Primary giant cell tumors of soft tissues (GCT-ST) are extremely rare soft tissue tumors, located in both superficial and deep soft tissues. They resemble osseous giant cell tumors morphologically and immunohistochemically. The tumor exhibits strong positive immunoreactivity for cluster of differentiation 68 (CD68) within multinucleated osteoclast-like giant cells and focal staining of mononuclear cells. Case reports describing the cytohistological features of this entity are very few. We report a case of GCT-ST of low malignant potential diagnosed on fine needle aspiration (FNA) and confirmed on histological and immunohistochemical studies.

Keywords: Cytology; giant cell tumor; soft tissue.
