PURPOSE
To detect Chlamydia pneumoniae (C. pneumoniae) gene in a patient with bilateral orbital musoca-associated lymphoid tissue (MALT) lymphoma.
DESIGN
Interventional case report.
METHODS
A 47-year-old Chinese man with recurrent bilateral orbital masses underwent surgical biopsy. Ophthalmologic and radiographic examinations, routine histology, immunohistochemistry, and molecular analysis for immunoglobulin heavy chain (IgH), bcl-2/IgH gene translocation, and Chlamydia genes were performed.
RESULTS
Pathology revealed orbital MALT lymphoma with B-cell monoclonality. In addition to IgH gene rearrangement, C. pneumoniae DNA was detected in the lymphoma.
CONCLUSIONS
The finding of C. pneumoniae molecular signatures in this case suggests a possible association of Chlamydia and orbital MALT lymphoma. The infection may contribute to the development of the lymphoma.
目的
检测一名双侧眼眶黏膜相关淋巴组织（MALT）淋巴瘤患者的肺炎衣原体（C. pneumoniae）基因。
设计
介入性病例报告。
方法
一名47岁复发性双侧眼眶肿物的中国男性接受了手术活检。进行了眼科和影像学检查、常规组织学检查、免疫组织化学检查以及免疫球蛋白重链（IgH）、bcl-2/IgH基因易位和衣原体基因的分子分析。
结果
病理显示眼眶MALT淋巴瘤伴B细胞单克隆性。除IgH基因重排外，在淋巴瘤中检测到肺炎衣原体DNA。
结论
该病例中肺炎衣原体分子特征的发现提示衣原体与眼眶MALT淋巴瘤可能存在关联。这种感染可能促进淋巴瘤的发生。
