Objective:
To explore the molecular pathological diagnosis of mucosa-associated lymphoid tissue lymphoma(MALTL).
Methods:
Sixty MALTL paraffin embedding specimens were analyzed retrospectively. The distribution of the primary lesion, morphology, immunophenotype, IgH gene cloning rearrangement were evaluated.
Results:
The main risk area for the patients with MALTL was gastric area(37%), in the second place was salivary gland(20%), in the third place was intestine (12%), orbit and ocular adnexa(12%); at low magnification, MALTL specimens manifasted diffuse growth majority, a few of nodular structure, lymphoma cell forms were diversified; The results of immunohistochemical detection showed that the CD20 and the BCL-2 were positive, the CD3, CD5, CD10, CD23, cyclin D1 and CD21 were negative, 17 specimen kappa or lambda express more obviously, their sensibility was 28.33%(17/60); 61.67%(37/60) developed IgH gene rearrangement, 19 specimen IgH gene rearrangement monoclonal and kappa or lambda were negative, the positive rate of both combined detections was 68.33%.
Conclusion:
The tissue morphologic characteristics and immuno-histochemistry detection are the basic means for MALTL diagnosis, the detection of IgH gene reasragement and Kappa or lamda restrictive expression has the practical importance for MALTL diagnosis, both combination can show higher positive rate for MALTL diagnosis.
