Primary pulmonary mucosa-associated lymphoid tissue lymphoma: a case report
open access
Abstract
Primary pulmonary lymphoma accounts only 0,5% of all primary lung neoplasms. Mucosa-associated lymphoid tissue (MALT) lymphoma is a low grade B-cell extranodal lymphoma. It is a quite infrequent entity, however it constitutes from 72% to 90% of all pulmonary lung lymphomas. Long-term stimulation of bronchus-associated lymphoid tissue by antigens, smoking, inflammatory disorders or autoimmune diseases are thought to be leading to the development of MALT lymphoma. We present the case of primary pulmonary mucosa-associated lymphoid tissue lymphoma. A 76-year-old man with a history of heavy smoking (22.5 pack years) was admitted to the hospital for a further diagnostics of an abnormal finding in the right lung visualized on the chest X-ray. The diagnostic process, including imagining studies did not reveal the etiology of a lesion in the right lung. The patient was qualified for surgical diagnostics. The histological finding confirmed extranodal marginal low-grade B-cell lymphoma of mucosa -associated lymphoid tissue.
