ReferencesOta Nevus 是一种良性皮肤色素沉着，主要发生在三叉神经区域，尤其是该神经第一、第二分支支配的眼部区域。该疾病亦称为眼部真皮黑变病，因黑素细胞滞留导致灰蓝色变色。通常表现为面部单侧出现，可能累及眼睛、面部皮肤，偶尔涉及口腔上颚。患者罹患眼部黑色素瘤和青光眼的风险较高。伊藤痣与 Ota Nevus 类似，但累及的神经区域不同。
Nevus of Ota is a benign melanosis that primarily involves the region of the trigeminal nerve distribution. The first and second divisions of the trigeminal nerve, namely the ophthalmic V1 and the maxillary V2 are most commonly involved. There is associated hyperpigmentation of the eye. Nevus of Ota is also known as ocular dermal melanosis. The characteristic gray-blue hyperpigmentation occurs due to entrapped melanocytes. Unilateral presentation is more common. The melanocytes are entrapped leading to gray-blue hyperpigmentation of the conjunctiva and sclera along with ipsilateral facial skin. There is an increased risk of uveal melanoma and glaucoma in these cases. Palatal involvement may also occur. Nevus of Ito is very similar to nevus of Ota except it differs in the territory of distribution. It was described by Minor Ota in 1954. It involves the distribution territory of lateral cutaneous brachial nerves of the shoulder and posterior supraclavicular nerves. Both of these diseases share similar pathophysiology.

Congenital dermal melanocytosis 又称蒙古斑。这是新生儿常见的一种胎记。它从出生时或出生后不久就在皮肤上表现为灰蓝色斑块。这些标记通常出现在下背部和臀部，肩部是下一个常见部位。它们在亚洲和黑人婴儿中更为常见，对男孩和女孩的影响相同。大多数情况下，它们会在1至6岁自行消退，且通常不需要任何治疗，因为大多是良性的。
Congenital dermal melanocytosis, also known as Mongolian spot or slate gray nevus, is one of many frequently encountered newborn pigmented lesions. It is a type of dermal melanocytosis, which presents as gray-blue areas of discoloration from birth or shortly thereafter. Congenital dermal melanocytosis is most commonly located in the lumbar and sacral-gluteal region, followed by shoulders in frequency. They most commonly occur in Asian and Black patients, affect both genders equally, and commonly fade by age 1 to 6 years old. Congenital dermal melanocytoses are usually benign and do not require treatment.
