[Ocular adnexal mucosa-associated lymphoid tissue lymphoma: a pathological and imaging study].
OBJECTIVE
To analyze the relationship of the pathological and clinical features of patients with ocular adnexal mucosa-associated lymphoid tissue (MALT) type lymphoma, and to provide a suggestion of preoperative diagnosis and treatment of MALT lymphoma.


METHODS
To analyze the clinical, imaging and histopathologic features of 20 cases (25 eyes) of MALT lymphoma retrospectively in the department of ophthalmology.


RESULTS
Among the 20 cases (25 eyes), 18 cases (21 eyes)were located in the orbit, and 2 cases (4 eyes) were at conjunctiva. MALT lymphoma had typical characters in CT, MRI and B scan imaging, Histopathological examination showed that all of the 20 cases (25 eyes) were B cell lymphoma. Monoclonal immunophenotype of 21 eyes were positive, 15 eyes kappa positive, 6 eyes lambda positive. 15 eyes CD45RA positive, 18 CD45RO low positive, 23 eyes CD20 positive and 24 eyes CD3 negative.


CONCLUSIONS
Patients with primary ocular adnexal MALT lymphoma had a similar pathological morphology with other locus. Through imaging we could get a preoperative diagnosis.
