CONTEXT: Mucosa-associated lymphoid tissue (MALT) lymphomas are most commonly found in the stomach, lungs, orbital soft tissue, salivary glands and thyroid. Involvement of the trachea is extremely rare. CASE REPORT: This report describes a rare case of MALT lymphoma of the trachea in a 71-yearold woman who presented with a one-year history of coughing, dyspnea, hoarseness and weight loss. There was an infiltrative lesion in the mid-trachea. The anatomopathological diagnosis was only made from the fifth endoscopic biopsy attempt. Immunochemotherapy consisting of rituximab, cyclophosphamide, vincristine and prednisone (R-COP) induced complete remission of the symptoms and endoscopic lesion. CONCLUSIONS: MALT lymphoma of the trachea is extremely rare and indolent disease. It has to be considered in the differential diagnosis of airway lesions. It is crucial to obtain an anatomopathological diagnosis from a specialized pathologist. Immunochemotherapy with R-COP induced complete remission of the disease.
