摘要：

Laryngeal mucosa-associated lymphoid tissue(MALT) lymphoma is rare.To the best of our knowledge, only 25 cases of laryngeal MALT lymphoma have been reported.Here,we report a case of laryngeal MALT lymphoma diagnosed in a 35-year-old female.After a diagnosis from a biopsy,the patient received two cycles of CHOP chemotherapy.18FDG PET/CT was performed,as the CHOP treatment was ineffective.PET/CT showed FDG accumulation only in the larynx and identified stage IE lymphoma.We switched from CHOP chemotherapy to radiotherapy.After 3 months,18FDG PET/CT scan showed that the lesions in the larynx were in complete remission after a dose of 27 Gy irradiation.A review of the literature on laryngeal MALT lymphoma and the use of PET/CT in MALT showed that radiotherapy is the first-line treatment for stage I and II MALT lymphoma.
