ReferencesOta Nevus 是一種良性皮膚色素沉著，主要發生於三叉神經區域，尤其是第一、第二分支所支配的眼部。此病亦稱為眼部真皮黑變病，因黑色素細胞滯留而呈灰藍色。通常出現在臉部單側，可累及眼睛、面部皮膚，偶爾涉及口腔上顎。患者罹患眼部黑色素瘤及青光眼的風險較高。伊藤痣與 Ota Nevus 類似，但影響的神經區域不同。
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，又稱蒙古斑，是新生兒常見的胎記之一。它於出生時或出生後不久，即在皮膚上呈現灰藍色斑塊。這些斑塊多出現在下背部和臀部，肩部則是第二常見的部位。此情況在亞洲及黑人嬰兒中較為常見，男女發生率相同。大多數情況下，斑塊會在 1 至 6 歲之間自行消退，通常不需要任何治療，因為它們大多是良性的。
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.
