Ear and Head Tumors

A 68-year-old woman arrived at our clinic with a slow-growing nodule in the buccal region, next to tooth 45. The patient had a 9-year history of a diagnosis of mucosa-associated lymphoid tissue-type lymphoma in the gastrointestinal region. She reported pain on palpation. In the intraoral examination, a submucosal nodule, sessile, of firm consistency and with the color of the mucosa was observed. The lesion did not appear on imaging exams. An excisional biopsy was performed under local anesthesia, because of the benign aspect, with a clinical diagnosis of pleomorphic adenoma. The histologic analysis showed atypical lymphocyte cells. Furthermore, the specimen showed positivity for CD20, Ki-67, and BCL-2. The diagnosis was of a lesion suggestive of MALT lymphoma. The patient was referred to and oncologist, where she underwent a computed tomography scan, but no other injured sites were found. The patient is under medical supervision.
