Ota Nevus 은 주로 삼차 신경 부위 주변의 피부가 양성으로 어두워지는 현상으로, 대부분 이 신경의 첫 번째와 두 번째 부분이 있는 눈 부위에 영향을 미칩니다. 안구 진피 흑색증이라고도 불리는 이 상태는 갇힌 멜라닌 세포로 인해 회청색 변색을 유발합니다. 이는 대개 얼굴 한쪽에 나타나며 눈, 얼굴 피부, 때로는 입천장에도 나타날 수 있습니다. 이 질환이 있는 사람은 눈 흑색종과 녹내장이 발생할 가능성이 더 높습니다. 이토 모반은 유사하지만 다른 신경 영역에 영향을 미칩니다.
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 는 몽골리안 스팟이라고도 알려져 있습니다. 신생아에게 흔히 나타나는 반점 유형입니다. 출생 시 또는 직후 피부에 회청색 반점이 나타납니다. 이 자국은 일반적으로 허리와 엉덩이에서 발견되며 어깨가 그 다음으로 흔한 위치입니다. 이는 아시아인과 흑인 유아에게 더 자주 발생하며 남아와 여아 모두에게 동일하게 영향을 미칩니다. 일반적으로 1~6세가 되면 저절로 사라지며 대부분 무해하므로 치료가 필요하지 않습니다.
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.
