Osteoclast-Like Giant Cell Tumors with a Carcinomatous Component of Parotid Gland / 대한이비인후과학회지

ABSTRACT

The giant cell tumor of the salivary gland is very rare. A 57-year-old man had noticed a mass in the right parotid area for several weeks. The diagnosis using aspiration cytology was a giant cell tumor possibly with a carcinomatous component. Parotidectomy was carried out. Histologically, the tumor consisted of evenly distributed osteoclast-like giant cells, mononuclear cells and two small foci of a carcinomatous component. Because so little is known about giant cell tumor of the salivary gland, we used the occasion of this case report to describe the cytologic, histologic and immunohistochemical characteristics that we observed.
