ABSTRACT

Background: Primary mucosa-associated lymphoid tissue (MALT) lymphoma of the trachea in a woman without any notable pathological history. Methods: Here we report the case of a 63-year-old woman without any pathological antecedents. Computed tomography of the chest showed a tumor process of the anterior wall of the trachea extended to the carina. Bronchoscopy was performed, and the results of a biopsy supported a diagnosis of mucosa-associated lymphoid tissue (MALT) lymphoma. No other lesions were detected in the systemic evaluation. The patient was fitted with an intra-tracheal prosthesis in Y and then treated with regional irradiation at a dose of 30Gy. Results: the patient presents a complete remission of her disease with the CT scan at 4 weeks of end of radiotherapy a disappearance of the tumor. Conclusions: external beam radiotherapy seems to be one of the most valuable strategies for treatment of MALT lymphomas of the central airway.
