Primary Tracheal Mucosa-Associated Lymphoid Tissue Lymphoma Treated with a Water-Jet Hybrid Knife: A Case Report.

Primary mucosa-associated lymphoid tissue (MALT) lymphoma of the trachea is very rare and is easily misdiagnosed as a bronchogenic carcinoma or benign tracheal tumor. Here, we report a clinical case where a new clinical approach involving a water-jet hybrid knife was employed in the diagnosis and treatment of primary tracheal MALT lymphoma.
