Linfoma não Hodgkin em cavidade oral: relato de caso

Abstract

Lymphomas are malignant neoplasms that occur due to changes in the differentiation and/or proliferation of lymphocytes or their precursors and present different clinicopathological aspects. These neoplasms are classified into two major groups: Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL). Non-Hodgkin's Lymphoma (NHL) can occur in nodal and extranodal regions of different anatomical sites, including the head and neck region. In the oral cavity, the occurrence of lymphomas is rare, accounting for approximately 2 to 10% of the neoplasms that affect this region, occurring in the palate, gingiva, buccal mucosa and floor of the mouth, without specific clinical characteristics, being clinically similar to many other diseases, such as advanced periodontal disease, osteomyelitis and other malignancies. In most cases, the involvement of the oral cavity represents part of a disseminated disease. The aim of this study is to report a case of follicular B-cell subtype NHL with primary manifestation in the buccal mucosa. The relevance of this study comes from the context in which NHLs are extremely rare entities in the oral cavity as the primary site and in the location of the buccal mucosa, representing a diagnostic challenge, due to the low index of clinical suspicion, the importance of the dental surgeon is also highlighted. early diagnosis of this pathology.
