Histological and microradiographical studies of human mandibular condyle.

Twenty-one clinically normal human mandibular condyles were examined by histologic and microradiographic methods obtaining some measurements. The histologic structures of condyle were quite different between the child group and other aged groups. The difference in the surface articular zone composed of the fibrous tissue was not so great in all age groups, while there was quite a difference in the structure in the remaining zones. It was clearly demonstrated by microradiogram that the osteons of the subarticular bone plate were more prominent in aging. Abnormal structures of the condyle were revealed in some individuals of the adult and old age groups, which were assumed probably to be the reactive remodelling against the functional changes of the temporomandibular joint.

Oral manifestations of acute promyelocytic leukemia.

A study was conducted of 16 patients with acute promyelocytic leukemia. The most common oral manifestations were hemorrhagic diathesis and leukemic involvement. There was gingival bleeding, petechiae, and ecchymosis of the oral mucosa, massive infiltration-induced gingival swelling, ulcerative glossitis, swelling of the tonsils, and facial palsy. Inflammatory stomatitis also occurred. Patients with acute promyelocytic leukemia had a higher incidence and severity of oral bleeding than those with other types of acute leukemia. However, the oral findings in our series were not necessarily specific for acute promyelocytic leukemia because the same oral symptoms occur in other forms of acute leukemia.

Adenoid squamous cell carcinoma of the oral mucosa: report of two autopsy cases.

Two autopsy cases of adenoid squamous cell carcinoma of the oral mucosa proper are presented. Consecutive histologic examinations confirmed that adenoid transformation had occurred directly from within the pre-existing usual squamous cell carcinoma during the course of the disease. The adenoid pattern was reproduced in the lymph node metastases in both cases. The behavior and autopsy findings were not significantly different from those of usual squamous cell carcinoma of the oral mucosa.

Double viral infection of the mouth in the cancer patient.

An autopsy case of renal cancer complicated with multiple oral ulcers is presented. Although serological tests were not available, double viral infection with herpes simplex virus and cytomegalovirus was suspected as causal agents in the retrospective examination. This infection may be a complication in the prolonged stage of cancer patients.
