Radial probe endobronchial ultrasound (RP-EBUS)-guided transbronchial lung biopsy successfully confirmed the diagnosis of primary PMZL-MALT in a patient with persistent pulmonary consolidation.
Case Report (n=1)
Highlights the utility of radial probe endobronchial ultrasound-guided biopsy in diagnosing rare pulmonary lymphomas presenting as nonspecific consolidations.
This case report presents a rare case of primary pulmonary marginal zone B‐cell lymphoma of mucosa‐associated lymphoid tissue (PMZL‐MALT). Follow‐up lung imaging performed 17 months after the initial presentation showed persistent pulmonary consolidation. After a radial probe endobronchial ultrasound (RP‐EBUS)–guided transbronchial lung biopsy, histopathological analysis confirmed the diagnosis of primary PMZL‐MALT. Notably, while RP‐EBUS is commonly used for solitary peripheral pulmonary lesions, its value in asymptomatic, bilateral, nonspecific consolidations—an easily misdiagnosed scenario often leading to unnecessary invasive procedures—remains underrecognized, which this case is aimed at highlighting. Our report is aimed at raising clinical awareness of this disease and promoting early diagnosis and treatment.
Ren et al. (Thu,) conducted a case report in Primary pulmonary marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (PMZL-MALT) (n=1). Radial probe endobronchial ultrasound (RP-EBUS)-guided transbronchial lung biopsy was evaluated on Diagnosis of primary PMZL-MALT. Radial probe endobronchial ultrasound (RP-EBUS)-guided transbronchial lung biopsy successfully confirmed the diagnosis of primary PMZL-MALT in a patient with persistent pulmonary consolidation.
