Bronchial-associated lymphoid tissue (BALT) lymphoma is a distinct subgroup of low-grade B-cell extranodal non- Hodgkin’s lymphoma, classified as marginal-zone lymphoma. This study was performed in order to assess the natural history of this rare entity. We evaluated retrospectively the clinical, radiological and histological features and to discuss the optimal management and prognostic factors through a literature review, of 4 patients with biopsy-proven BALT lymphoma collected at department of pathology of Erasme from 2010 to 2014. The group of four patients included tree women and one man, with a median age of 69 years (Range: 45-84 years). One of 4 patients presented fever chest pain within bronchopneumonia, other patients were asymptomatic with an incidental finding after preoperative radiological assessment.
Computed tomography (CT), which is more sensitive than standard radiography, has demonstrated that the lesions are unilateral (n=3) and multiple (1 patient), without lymph node enlargement. All of our patients has a thoracoscopy diagnosis and therapeutic. Macroscopy: whitish lesions poorly defined. Microscopy: MALT lymphoma low grade (CD20 +, bcl2+). All of our patients have just a local treatment without chemotherapy and three were alive after a follow extended.
