Cancer is considered as one of human's complications, particularly in oral and maxillofacial region which leads to undesirable effects and sometimes endangers individual's life. The aim of this study was to investigate the frequency of maxillofacial malignant tumors, during 13 years, (1985- 1998),in Hamedan. Three hundred and eighty - six records of biopsies were selected from the private files...
Introduction & Objective: The lymphomas are a group of malignant solid tumors that involving cells of the lymphoreticular or immune system. While primary symptoms of lymphoma could involve head and neck region thus have significant value for dentists.

PURPOSE To estimate size overlap between large choroidal nevi and small choroidal melanomas by using plotted frequency distributions of tumor size. METHODS Frequency distributions of largest linear basal diameter (LBD) and thickness (TH) of choroidal nevi and melanomas were plotted from published data and cases in the senior author's practice. Relative frequencies of choroidal nevi and melano...
