摘要

作者报告了一名患有太田痣(眼表皮黑素细胞增多症)的患者,她出现了右眼眶色素上皮样黑素细胞瘤。患者是一名 36 岁女性,因眼球外凸和复视 3 个月就诊。核磁共振成像显示病变呈膨胀性,与右侧下直肌粘连,眶上裂扩大,右侧海绵窦充盈。通过经结膜下穹窿入路切除眼眶肿块后,发现病变部位有大量色素沉着。解剖病理研究显示,诊断结果为色素上皮样黑色素细胞瘤。正电子发射断层扫描未显示任何转移。患者接受了放疗,眼球突出和复视情况有所改善,3 年来没有发现远处转移。色素上皮样黑色素细胞瘤和非典型蓝痣一样,属于重度色素性肿瘤,其特点是黑色素生成突出,恶性程度较低。

Orbital Pigmented Epithelioid Melanocytoma Tumor Associated With Nevus of Ota (Oculodermal Melanocytosis).
The authors report a patient with nevus of Ota (oculodermal melanocytosis) who presented with pigmented epithelioid melanocytoma in the right orbit. A 36-year-old female patient attended with proptosis OD and diplopia for 3 months. MRI disclosed an expansive lesion adhered to the right inferior rectus muscle, enlargement of the superior orbital fissure, and filling of the right cavernous sinus. Excision of the orbital mass through a transconjunctival inferior fornix access disclosed a heavily pigmented lesion. Anatomopathological study revealed a diagnosis of pigmented epithelioid melanocytoma. A positron emission tomography scan did not show any metastasis. The patient was submitted to radiotherapy, had an improvement of the proptosis and diplopia, and showed no distant metastases for 3 years now. Pigmented epithelioid melanocytoma belongs to the group of heavily pigmented neoplasms, as do atypical blue nevus, which is characterized by prominent melanin production and a low degree of malignancy.
