Ang Ota Nevus ay isang benign darkening ng balat pangunahin sa paligid ng trigeminal nerve area, kadalasang nakakaapekto sa mga rehiyon ng mata na pinaglilingkuran ng una at pangalawang dibisyon ng nerve na ito. Ang kundisyong ito, na tinatawag ding ocular dermal melanosis, ay nagdudulot ng kulay abo-asul na kulay dahil sa mga nakulong na melanocytes. Karaniwan itong lumilitaw sa isang bahagi ng mukha at maaaring may kasamang mata, balat ng mukha, at kung minsan ang bubong ng bibig. Ang mga taong may ganitong kondisyon ay may mas mataas na pagkakataon na magkaroon ng melanoma sa mata at glaucoma. Ang Nevus ng Ito ay magkatulad ngunit nakakaapekto sa iba't ibang lugar ng nerve.
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 ay kilala rin bilang Mongolian spot. Ito ay isang karaniwang uri ng birthmark na nakikita sa mga bagong silang. Lumilitaw ito bilang kulay-abo-asul na mga patch sa balat mula sa kapanganakan o ilang sandali pagkatapos. Ang mga markang ito ay karaniwang matatagpuan sa ibabang likod at pigi, na ang mga balikat ang susunod na karaniwang lokasyon. Ang mga ito ay mas madalas sa Asian at Black na mga sanggol, na nakakaapekto sa parehong mga lalaki at babae nang pantay. Karaniwan, kusang nawawala ang mga ito sa edad na 1 hanggang 6 na taon at sa pangkalahatan ay hindi nangangailangan ng anumang paggamot dahil kadalasan ay hindi nakakapinsala.
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.
