Abstract
Lymphomas can be simply defined as malignant neoplasms of lymphocytes and their precursor cells. We report a case of a diffuse large B-cell lymphoma of the maxilla, in an 11-year-old male patient who reported with a diffuse swelling of the maxillary labial mucosa accompanied with oral candidiasis. A subsequent biopsy and immunohistochemistry were instrumental in this diagnosis. What makes this case significant is that the incidence of primary DLBCL in the oral cavity of a minor which is not very common and has rarely been specified earlier in the literature.
