Linfoma pulmonar primário – a propósito de um caso clínico
Palavras-chave:
Linfoma pulmonar, BALT, MALTResumo
Descreve-se o caso de uma doente de 64 anos de idade que se
apresentou no Serviço de Urgência com queixas de tosse irritativa,
astenia intensa e perda ponderal não quantificada, com cerca de
dois meses de evolução. Dos antecedentes pessoais destaca-se
artrite reumatóide, em remissão há vários anos. A radiografia
torácica evidenciava uma massa ovóide no hilo esquerdo. Foi
só após a segunda broncofi broscopia com biopsia e exame
anatomopatológico que se chegou ao diagnóstico de linfoma
pulmonar primário.
Os linfomas pulmonares primários são raros. A forma mais
habitual de apresentação é o linfoma B não-Hodgkin da zona
marginal, extranodal, originado no tecido linfóide associado à
mucosa brônquica (BALT - Bronchus Associated Lymphoid Tissue),
também denominado linfoma pulmonar primário do tipo MALT
(Mucosa Associated Lymphoid Tissue).
