Mantle cell lymphoma (MCL) is a subtype of Non-Hodgkin's lymphoma (NHL). MCL frequently affects extranodal sites while endobronchial involvement is uncommon. Only 5 cases of MCL with endobronchial involvement have been previously reported.
A 56-year-old male patient arrived at the hospital complaining of a dry cough. A mass in the right upper lobe of the lung was revealed in Chest computed tomography (CT). Right lung hilar and mediastinal lymphadenopathies were also found by CT scan. The patient was diagnosed with central-type lung cancer with multiple lymph node metastases after positron emission tomography (PET) CT scan examination. The fiber optic bronchoscope examination revealed diffuse neoplasm infiltration in the inlet of the right up lobar bronchus. The patient was finally diagnosed with MCL based on the bronchoscopy and mediastinoscopy biopsy results.
MCL could masquerade as central type lung cancer. An endobronchial biopsy examination is necessary for the early diagnosis of MCL.
Core Tip: We reported a case of mantle cell lymphoma (MCL) with endobronchial involvement. MCL with endobronchial involvement is very rare. Only five such cases have been previously reported. Positron emission tomography - computed tomography is recommended for differential diagnosis and detection of extranodal sites of MCL. A pathological diagnosis can be made based on an endobronchial biopsy by bronchoscopy but doctors should prompt efforts to establish enough tissues.
