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

| 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
pulmonary malignancies. Although the time to diagnosis can be delayed because most patients are asymptomatic and investigations are usually driven
by the accidental finding of abnormal lung imaging studies, it has an indolent course and a good prognosis. Here we report the case of an asymptomatic
female patient with a nodular lung opacity that was found to persist five months after an episode of community-acquired pneumonia. A final diagnosis of
pulmonary MALT lymphoma was obtained after an extensive diagnostic work-up. |

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 pulmonary malignancies.

RESUMO: O linfoma do tecido linfóide associado à mucosa (MALT) é um linfoma extranodal que surge em vários tecidos epiteliais, incluindo o estômago, as glândulas salivares e o pulmão. O linfoma MALT pulmonar tem origem no parênquima e/ou brônquios e é raro, representando 0.5-1% dos tumors primários do pulmão. Pode haver um atraso no tempo até ao diagnóstico porque a maioria dos pacientes é assintomática, sendo as investigações geralmente conduzidas pelo achado acidental de exames de imagem pulmonares alterados. Este linfoma tem um curso indolente e um bom prognóstico. Aqui expomos o caso de uma paciente assintomática com uma opacidade nodular que persistiu 5 meses após um episódio de pneumonia adquirida na comunidade. O diagnóstico final de linfoma MALT pulmonar foi obtido após uma investigação diagnóstica extensa. |
