Abstract

Primary cutaneous CD8-positive aggressive epidermotropic cytotoxic T-cell lymphoma (PCAE-CTL) is a rare subtype of cutaneous T-cell lymphoma with a poor prognosis. We herein report a case of PCAE-CTL accompanied by anti-Ma2 antibody-positive paraneoplastic encephalitis. A 33-year-old woman with erythema and disturbance of consciousness was diagnosed with PCAE-CTL by a skin biopsy. Head magnetic resonance imaging revealed bilateral medial temporal lobe hyperintensity, and anti-Ma2 antibody in the cerebrospinal fluid was positive. She was diagnosed with concurrent anti-Ma2 antibody-positive paraneoplastic encephalitis. In cases of lymphoma with brain lesions, invasion of the central nervous system by lymphoma and paraneoplastic encephalitis should be considered.

原发性皮肤cd8阳性侵袭性表皮细胞毒性t细胞淋巴瘤并发副肿瘤脑炎。

原发性皮肤cd8阳性侵袭性表皮细胞毒性t细胞淋巴瘤（PCAE-CTL）是一种罕见的皮肤t细胞淋巴瘤亚型，预后较差。我们在此报告一例PCAE-CTL伴抗ma2抗体阳性副肿瘤脑炎。一名33岁女性，红斑和意识障碍，通过皮肤活检诊断为PCAE-CTL。头部磁共振示双侧内侧颞叶高信号，脑脊液抗ma2抗体阳性。她被诊断为并发抗ma2抗体阳性副肿瘤脑炎。在淋巴瘤伴脑病变的病例中，应考虑淋巴瘤和副肿瘤脑炎对中枢神经系统的侵犯。
