Abstract
The patient was a clerk, 45 years old male, came to our hospital complaining a swelling in the left cheek, and was hospitalized suspected of the mixed tumors of the left parotid gland on Feb. 19, 1959.
The tumor was as large as a child's fist, its hardness was the same as bone, and it had no fluctuation, no change in hardness according to location and no metastasis to circumferential tissues.
In an X ray examination, the image of deficient shadow was seen in the left maxilla. The excision of the tumor was performed under a local anesthesia, and its findings were as follows the parotid gland was in fibriform hypertrophy and was not tumorous. On its median side, a tumor as large as a child's fist was found growing on the posterior superior part of the left maxilla.
It was covered with the periosteum, assumed a dark-red colour, and a slight fluctuation was observable. No metastasis to circumferential tissues was observable, its boundary was clear but it spread to a wide range in the inferior jaw. The tumor was excised as large as possible, and the rest of it was curetted.
The excised lump was weighted about 40 gr and measured 6.0×4.0×3.0cm.
Histologically, it was the giant cell tumour and the findings showed a typical pattern which consisted of the spindle shaped cells and the giant cells. Both cells presented no malignant pattern.
The giant cell was 50-100μ in diameter and had 10-30 nuclei.
