ReferencesOta Nevus 是一种良性皮肤色素沉着，主要发生在三叉神经区域，尤其是第一、第二分支支配的眼部区域。该病也称为眼部真皮黑变病，因黑素细胞滞留导致灰蓝色变色。通常单侧出现于面部，可能累及眼睛、面部皮肤，偶尔波及口腔上颚。患者罹患眼部黑色素瘤和青光眼的风险较高。伊藤痣与其相似，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(蒙古斑) 是新生儿常见的一种胎记。它在出生时或出生后不久表现为皮肤上的灰蓝色斑块。常见部位为下背部和臀部，肩部是次常见位置。该标记在亚洲和黑人婴儿中更为常见，男女婴儿发病率相同。通常在 1 至 6 岁之间自行消退，一般无需治疗，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.
