The odontogenic adenomatoid tumor. A comprehensive study of twenty new cases.

Twenty new cases of odontogenic adenomatoid tumor are added to the literature, bringing the total number of reported cases to 152. The clinical, radiographic, and microscopic findings in these cases support the previously reported data for this lesion. The odontogenic adenomatoid tumor is a benign lesion which arises from residual odontogenic epithelium. It should be treated conservatively, as there is no indication that this lesion will recur. The histogenesis of this lesion, as well as the origin of the esinophilic droplet material, is discussed.

Keratinization in odontogenic tumors.

The potential of odontogenic epithelium to keratinize in the form of ghost cells is demonstrated in the histologic variants of a number of odontongic tumors. Although the cells lack keratohyaline granules, they do contain abundant tonofilaments and probably represent an altered form of keratin. The presence of this material in odontogenic tumors does not appear to alter clinical occurence or clinical behavior.

Fibrous lesions of the skin and mucous membranes which contain stellate and multinucleated cells.

Various fibrous lesions of the skin and mucous membranes share the common histologic feature of stellate and multinucleated fibroblasts. These cells are conspicuous under the light microscope because they contain a well-developed, rough endoplasmic reticulum which, because of its high RNA content, stains basophilic. These characteristic cells are a nearly constant feature of the retrocuspid papilla. They are apparent in about half of the fibrous papules of the nose and abundant in about 1 per cent of irritation fibromas. These lesions most likely represent a nonspecific proliferation of the lamina propria or papillary dermis to various stimuli.

Squamous odontogenic tumor. Report of six cases of a previously undescribed lesion.

Six cases of a previously unnamed oral lesion are described and the name squamous odontogenic tumor is applied. The lesion causes radiolucent areas of bone destruction adjacent to the roots of teeth. In one case there were multiple separate lesions. Light microscopy revealed numerous islands of benign squamous epithelium with focal areas of keratinization and calcification. Electron microscope examination in one case showed normal squamous epithelial cells with abundant glycogen granules, tonofilaments and myelin bodies. Complete surgical excision seems the best therapy, as only one lesion recurred following treatment.
