BACKGROUND Oral lymphoma is the second most common malignancy of the head and neck region after malignant epithelial tumors. OBJECTIVES Considering the lack of a multicenter study on the frequency of oral lymphoma in Iran, this study aimed to assess the relative frequency of oral lymphomas in Iran during a 6-year period. MATERIALS AND METHODS This multicenter, retrospective, cross-sectional...

Lymphomas arising within the oral cavity account for only 3.5% of all oral malignancies. Diffuse large B-cell lymphoma is a non-Hodgkin lymphoma subtype characterized by diffuse proliferation of large neoplastic B lymphoid cells. This paper reports a case of diffuse large B-cell lymphoma affecting the oral cavity of a Brazilian woman, along with its clinical, microscopical, immunohistochemical,...

Non-Hodgkin lymphoma (NHL) represents the third most common group of malignant lesions of the oral cavity, following squamous cell carcinomas and salivary gland neoplasms. It accounts for 3-5% of all malignant lesions of the oral cavity [1]. Further, only 1% of all lymphomas are primary oral cavity lymphoma. Non-Hodgkin’s lymphoma of the tongue is extremely rare. It can arise from Waldeyer’s ri...

Lymphomas of the oral cavity are a rare complication of advanced HIV/AIDS disease. The clinical appearance of these neoplasms includes masses or ulcerative lesions that involve the oral soft tissue and the jaw as the predominant manifestation. We report the case of a patient with AIDS who developed diffuse large B-cell non-Hodgkin’s lymphoma of the oral cavity during highly active antiretrovira...

Non-Hodgkin’s lymphoma is a heterogeneous malignancy originating from proliferation of lymphoid cells or their precursors. , we report a case of a 6-year-old Iranian male child admitted at the Department of Oral Medicine, School of Dentistry, Mashhad, Iran, in March 2019.

Lymphomas are solid malignant tumors having a wide spectrum of clinical and pathological features. Non-Hodgkin’s lymphoma (NHL) is a subtype of lymphoma with two-thirds of the cases presenting as lymph node enlargement. The remaining one third of NHL cases has been reported in the extranodal sites, including the gastro intestinal tract, Waldeyer’s ring, bone, skin, and brain. Intraoral non-Hodg...
