Summary

The relationship between the radiographic features of jaw bone destruction and the histopathological features of tumor cells in 115 squamous cell carcinomas of the lower gingiva was investigated. The radiographic features were classified into four patterns as saucer-shaped, permeated, geographic and moth-eaten. Histopathologically, the cases were divided into three groups, a) the highly differentiated type showing papillary and nest structure well keratinized, b) the moderately differentiated type showing small cord and strand structure with moderate keratinization, and c) the poorly differentiated type showing marked cellular dissociation with poor keratinization. In the group of saucer-shaped, permeated, geographic and moth-eaten type, the proportion of histologically highly differentiated tumors was high. Namely, highly differentiated tumors tended to reveal a fairly mild and compressive resorption and poorly differentiated tumors showed more invasive and aggressive potential to the bone.

This study suggested that the radiographic images of the mode of bone destruction in squamous cell carcinomas of the gingiva are influenced by the histopathological nature of the tumor cells.
