A Case of MALT Lymphoma Occurrence in the False Vocal Cord

Abstract

Mucosa-associated lymphoid tissue (MALT) lymphoma in the larynx is rare. Its treatment has not been standardized and radiation therapy or radiochemotherapy are often selected for stage I E. We report on a case of surgical treatment for stage I E laryngeal MALT lymphoma which occurred in the false vocal cord. The patient was 44-year-old woman exhibiting hoarseness. Fiberscopic examination revealed a tumorous lesion of the right false vocal fold’s surface smooth. The lesion was treated by excisional biopsy under general anesthesia using a CO₂ laser. Histological diagnosis was stage I E MALT lymphoma in the larynx. Her voice has improved after surgery. Recurrence has not been observed to the present. Excisional biopsy for localized lesions increases the certainty of diagnosis. And, it can be a radical surgery. Observation is one of the choice for patients of Stage I E MALT lymphoma in the larynx after excisional biopsy.
