Ota Nevus benigna est obscuratio cutis praecipue circa nervum trigeminalem aream, maxime circa regiones oculorum, quibus prima et secunda divisio huius nervi inserviunt. Haec conditio, etiam melanosin dermal ocularis dicta, colore cinereo-caeruleo ex melanocytis capti facit. Solet ab una parte faciei apparet, et involvat oculum, cutem faciei, et quandoque palatum oris. Homines cum hac condicione maiorem occasionem habent ut melanoma et glaucoma oculi enucleandi. Nevus Ito similis est, sed nervum diversis locis afficit.
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 etiam macula Mongolica nota est. Commune genus notae notae in fœtibus visae sunt. Apparet sicut griseo-caeruleum inaequalis in cute a nativitate vel paulo post. Hae notae typice repertae sunt in clunibus dorsi inferioris, cum scapulis communi loco proximus. Frequentiores sunt in infantibus Asiaticis et Nigris, aeque pueros ac puellas afficientes. Fere deficiant sua aetate 1 ad 6 annos fereque non egent curatione, ut plerumque innocui.
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.
