Diffuse large B-cell lymphoma of the palate secondary to Sjo<spacing diaeresis>gren syndrome: A case report

We herein report a case of diffuse large B-cell lymphoma (DLBCL) of the palate secondary to Sjo center dot gren syndrome. A 55-year-old woman was found to have redness of the palate at a nearby dental clinic and was referred to the oral surgery department of another hospital in February 2007. It was difficult to distinguish mucosa-associated lymphoid tissue (MALT) lymphoma from severe inflammation based on a biopsy, so the patient was referred to our department. The mass showed redness, measuring 25 x 20 mm, and was smooth-surfaced and elastic hard. The results of a rebiopsy in our department suggested the possibility of MALT lymphoma, but the diagnosis could not be confirmed. At the same time, a systemic examination revealed complications with Sjo center dot gren's syndrome. The mass subsequently increased in size, and the entire mass was resected to confirm the diagnosis. The pathological final diagnosis was DLBCL. Complete remission has been maintained for over 14 years since therapy was performed.
