Extranodal NK/T Cell Lymphoma, Nasal Type with Palatal Involvement: A Rare Case Report and Literature Review


T-cell lymphomas are infrequently encountered in the head and neck area, with the most common subtype being Extranodal NK/T cell lymphoma, nasal type (ENKTL-NT). ENKTL-NT shows a predilection for midline facial structures presenting with ulcerative destructive lesions, whereas palatal involvement is one of the most prominent signs from the oral cavity. Herein, we describe a case of a 76-year-old Greek man with nasal obstruction and an extensive painful necrotic ulcer with ragged borders on the left distal portion of the soft palate and palatine tonsil of 4-months duration. After an initial non-diagnostic biopsy from the nasopharynx, a second incisional biopsy from the palatal lesions was performed. Histopathology was suggestive of an angiocentric lymphoproliferative neoplasm and immunohistochemical examination and in situ hybridization for EBV RNA led to a final diagnosis of ENKTL-NT. The patient was placed under combined chemotherapy and radiotherapy and no recurrence has been noted. Additionally, a retrospective review of the cases in the English literature with an established diagnosis of ENTKL-NT between 2000 and 2019, based on the latest WHO classification of Head and Neck tumors, is performed.
