Subglottic MALT Lymphoma of the Larynx - More Attention to the Glottis

Background: Mucosa-associated lymphoid tissue (MALT) lymphoma of the larynx is a rare but well-documented entity which may arise from chronic inflammatory process. Supraglottic left regions are predominant due to unknown reason. Case Report: We present the case of a 62-year-old man with a dry cough, stridor and developing exertional dyspnea. This subglottic almost circumferential MALT lymphoma showed a temporary distinct disappearance after cortisone administration during the diagnostic process. Bronchoscopy confirmed the diagnosis of a primary MALT lymphoma of the larynx. The patient received chemotherapy according to CHOP scheme plus rituximab. A reliable post-treatment care period of 15 months showed no sign of recurrence. Conclusion: MALT lymphoma of the larynx are believed to arise from preexisting or acquired lymphoid tissue of the upper airway. Acquired lymphoid tissue is documented in the supraglottic region and may be associated with a chronic inflammatory process. However, in subglottic cases it is unclear whether the chronic inflammation arises from a local or systemic process.
