Giant cells in soft tissue (ST) tumors are rare, pose great challenges to treating clinicians, and diagnosing pathologists. Common lesion with giant cells includes benign conditions such as nodular fasciitis to highly malignant lesions such as giant cell variant of malignant fibrous histiocytoma and extraskeletal osteosarcoma. Giant cell tumors of ST, extension of bony lesion to the ST are also rare possibilities. Recently, giant cell fibroblastoma and dermatofibrosarcoma protuberans have also been added to this list. These tumors show unpredictable behavior; some patients are cured by simple surgical excision whereas others develop metastasis. Diagnosing these in cytology is still more challenging. We report here a rare case of a giant cell-rich dermatofibrosarcoma protuberans in a 23-year-old male who presented with ST lesion in left forearm since 6 months. The lesion was predicted in fine-needle aspiration cytology and confirmed later with histopathology. When evaluated along with clinical features, the cytological features are very useful to distinguish between these tumors with giant cell morphology.
