A Case of Laryngeal MALT Lymphoma that Disappeared Spontaneously

Abstract

MALT lymphoma is a low-grade B-cell lymphoma. Although it can develop in any organ, laryngeal MALT lymphoma is extremely rare, and is reported to account for less than 1% of all laryngeal malignancies. An 80-year-old woman was admitted to our hospital after she was diagnosed as having a subglottic mass by a neighborhood doctor whom she consulted because of a few months’ history of hoarseness of voice. She underwent laryngeal microsurgery, and was referred to the hematology department because histopathology led to the laryngeal MALT lymphoma. Treatment was considered, but then, in consideration of her age, etc., it was decided to follow her up at the outpatient department. One and a half years after the operation, the subglottic mass had disappeared spontaneously, and it was considered as a case of spontaneous disappearance of a laryngeal MALT lymphoma.
