Giant Cell Tumor of Phalanx – An Unusual Site
Giant Cell Tumor (GCT) is a locally aggressive bone tumor typically affecting the ends of long bones with fewer than 5% of cases involving the tubular bones of the hands and feet. At these rare sites, other differential diagnosis have to be considered and ruled out based upon the clinical, radiological and histopathological findings. We came across a case of giant cell tumor of the base of proximal phalanx of index finger in a 34-year-old male in whom the clinical presentation, radiological finding and most importantly the key features on histopathological examination helped us clinch this rare diagnosis. Through this case we understood the importance of differentiating features of GCT from other giant cell lesions of bone that form the basis of the final diagnosis, that is crucial in order to decide the line of management.
