A case of mesenchymoma in the oral cavity clinically resembling a large pleomorphic adenoma

A report is made of a 52-year-old male whose main complaint was a painless tumor at the right side of the palate resulting in speech disturbance. He was diagnosed as a case of what Stout called benign mesenchymoma. Some discussion is also made of the tumor pathology in terms of genetic factors, predirective sites, age range, sex differences and therapy.

Cytochemical study of exfoliated cells of oral mucosa. I. The glycogen deposition and keratinization

Cytochemical studies of glycogen of oral mucosa cells have been made on the smears by freeze-drying and PAS staining. The specimens were obtained from different areas of oral cavity of 77 human subjects and an attempt was made to find some interrelation amoung glycogen deposition, keratinization and inflammation. The largest glycogen deposition was found in the mucosa cells from mouth floor and cheek, a little in those from gingiva and quite a small or no glycogen in those from mucosa of hard palate and tongue. In gingiva the cells showing much more keratinization were less in glycogen contents, and vice versa. In inflammation some increase in glycogen contents were found in the gingivitis and the highest glycogen content in the cases of denture irritation of the palate as far as the present observation is concerned.
