Pulmonary MALT lymphoma – when an opacity persists too long: a case report and literature review

ABSTRACT Mucosa-associated lymphoid tissue (MALT) lymphoma is an extranodal lymphoma arising in a number of epithelial tissues, including stomach, salivary gland and the lung. Pulmonary MALT lymphoma originates in the parenchyma and/or bronchi and is a rare disease, representing 0.5-1% of primary p...
