Implication

A case details the diagnosis of MALT lymphoma after repeated pneumonia treatments in an older adult, highlighting the need for early tissue diagnosis.

Key Points

The aim is to highlight the diagnostic challenges of primary pulmonary lymphomas that mimic infections.
A 60-year-old man with persistent pneumonia underwent bronchoscopy and biopsies that confirmed MALT lymphoma.
Immunohistochemical analysis using markers like CD20 and CD79a was employed to identify lymphoma.
The patient received six cycles of bendamustine-rituximab therapy and subsequent evaluations.
Initial bronchoscopy revealed MALT lymphoma, diagnosed after months of antibiotic treatment without improvement.
Follow-up revealed only post-inflammatory changes, and the patient had a satisfactory clinical outcome after corticosteroid treatment.
The case emphasizes the importance of biopsy in persistent pulmonary conditions.
