Primary malignant melanoma of the orbit is a rare clinical entity. We report the clinical course and present the light and electron microscopic findings in a case arising in a cellular blue naevus. While most orbital melanomas are associated with a naevus of Ota, there was no clinically visible abnormal pigmentation in our patient. The possible origin of the tumour cell and its ultrastructural features are discussed.
眼眶原发性恶性黑色素瘤是一种罕见的临床病症。我们报告了一例起源于细胞性蓝色痣的病例的临床病程，并展示了其光镜和电镜检查结果。虽然大多数眼眶黑色素瘤与太田痣有关，但我们的患者并无临床上可见的色素沉着异常。本文讨论了肿瘤细胞的可能起源及其超微结构特征。
