Pleomorphic Mantle Cell Lymphoma of the Tongue Base Presenting With Dysphagia.

Objectives: We aim to increase awareness of pleomorphic mantle cell lymphoma as a rare, but aggressive form of lymphoma with propensity for recurrence in secondary locations.

Methods: We report the case of a 70-year-old man who presented with chronic post-nasal drainage, dysphagia, and voice changes caused by a tongue base mass.

Results: Partial excision and pathology showed a pleomorphic mantle cell lymphoma, and radiation treatment was completed. A regional recurrence was detected 3 years later and treated with radiation. He had no evidence of disease 17 months after treatment of the recurrence and is under close surveillance.

Conclusions: Pleomorphic mantle cell lymphoma is an aggressive subtype of non-Hodgkin lymphoma that can affect the head and neck. Confirming the diagnosis with immunotyping and genotyping from fresh specimens can guide appropriate treatment and then close clinical follow-up.
