ReferencesKo te Ota Nevus he āhua pouri o te kiri i te nuinga o te taha o te rohe o te nerve trigeminal; te nuinga ka pā ki ngā rohe o te kanohi e mahia ana e te wehenga tuatahi me te wehenga tuarua o tēnei nerve. Ko tēnei āhuatanga, e kīia ana ko te ocular dermal melanosis, ka pāheke te tae hīnāpuru nā ngā melanocytes kua mau. I te nuinga o te wā ka puta ki tētahi taha o te kanohi, ka uru pea te kanohi, te kiri kanohi, ā, i ētahi wā ko te tuanui o te waha. Ko ngā tāngata e pā ana ki tēnei mate ka nui ake te tūpono ki te whakawhanake i te melanoma kanohi me te glaucoma. He rite tonu te Nevus o Ito, engari ka pā ki ngā wāhi nerve rerekē.
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, 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.
