Ota Nevus 是一种良性皮肤变黑，主要发生在三叉神经区域周围，主要影响该神经第一和第二分支所服务的眼睛区域。这种情况也称为眼部真皮黑变病，由于黑素细胞滞留而导致灰蓝色变色。它通常出现在面部的一侧，可能累及眼睛、面部皮肤，有时还累及口腔顶部。患有这种疾病的人患眼部黑色素瘤和青光眼的机会较高。伊藤痣与此类似，但影响不同的神经区域。
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，肩膀是下一个常见的位置。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。通常，它们会在 1 至 6 岁时自行消失，并且通常不需要任何治疗，因为它们大多是无害的。
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.
