• Giant cell‐rich osteosarcoma is a rare histologic variant of conventional osteosarcoma that affects mainly the extremities. Extraskeletal giant cell‐rich osteosarcoma is therefore exceedingly rare. Here, we report the first case of this uncommon tumor involving the parotid gland in a 62‐year‐old male who presented with initial right jaw swelling. Radiologic work‐up revealed a 6.2 cm mass involving the right parotid gland. Fine‐needle aspiration cytology showed numerous multinucleated giant cells in a background of dyshesive epithelioid cells and rare clusters of spindle stromal cells, suspicious for malignancy. The subsequent excisional biopsy showed histopathologic features diagnostic for giant cell‐rich osteosarcoma. Diagn. Cytopathol. 2016;44:1107–1111. © 2016 Wiley Periodicals, Inc.
