하악골에서의 치성각화낭과 편평치성종양의 동시 발현:

SIMULTANEOUS OCCURRENCE OF AN ODONTOGENIC KERATOCYST AND SQUAMOUS ODONTOGENIC TUMOR IN THE MANDIBLE : A CASE REPORT AND IMMUNOHISTOCHEMICAL STUDY

A squamous odontogenic tumor (SOT) is rare disease and it is believed to originate from epithelial rests of Malassez of the periodontal membrane. Neither sex nor site predilection in either jaw has been established. Some lesion can be shown in juxtaposition in tooth roots. Although most lesions remain smaller than 2 cm, our cases involved a half of left mandibular ramus. The exact pathogenesis is still unknown. We report a case of SOT including the results of immunohistochemical study of pancytokeratin and p53.
