RESUMO
Lymphoma is a group of cancers that originates in the lymphatic system, but extranodal regions may be involved. As the head and neck areas are in the field of dentistry so a dentist has an important role in early diagnosis. The aim of this study was to evaluate the prevalence of lymphoma and involvement of cervico-facial tissues in patients with Hodgkin disease and non-Hodgkin's lymphoma. This descriptive study was conducted on medical records of 55 patients presented lymphoma, 9 cases with Hodgkin's disease [HD] and 46 cases with Non Hodgkin's Lymphoma [NHL], mainly for involvement of cervico-facial tissues and lymphadenopathy in cancer department of Iman Khomaini Hospital [2004]. Data was analysed by using SPSS 11 statistical software. Data revealed that the mean age in patients with HD was 47 +/- 7.18 and in NHL, 55 +/- 18 years old. The most site of lymphadenopathy was observed in the neck [88.8 in HD and 56.5 in NHL]. In 17.4% of patients with NHL, lymphadenopathy was found in submandibular, parotid and submental regions. According to the staging, 61% of patients were in stages I and II. The most common diagnostic method was incisional biobsy. Attention to cervico-facial and oral manifestation of lymphoma is effective in early diagnosis
