Abstract:
Objective: To explore the cytopathologic features and differential diagnostic essentials of the lung mucosa-associated lymphoid tumor(MALT).Methods: The fine needle aspiration(FNA) tissues and bronchi smears of 4 cases of MALT were examined by cytology,histology and immunohistochemistry respectively.Results: Cytologically,3 of the 4 cases were definitely diagnosed as lymphoid tumor and 1 suspected of small cell undifferentiated carcinoma,while histopathologically,all were diagnosed as MALT.The neoplastic cells were positive for CD20 and CD79a,but negative for CD3,CD5,CD10,CD45RO,CKpan and EMA.Conclusion: MALT is a rare pulmonary lymphoma difficult to be diagnosed.The definite diagnosis of pulmonary MALT depends on the cytology of FNA and bronchi smears,histopathology,and immunohistochemistry.
