Ota Nevus ndi khungu lodetsedwa bwino la khungu makamaka mozungulira dera la mitsempha ya trigeminal, makamaka chigawo cha diso chomwe chimaperekedwa ndi magawo oyambirira ndi achiwiri a mitsempha iyi. Matendawa, omwe amatchedwanso ocular dermal melanosis, amachititsa kuti khungu likhale lotuwa chifukwa cha ma melanocyte omwe atsekeredwa. Kaŵirikaŵiri amawonekera mbali imodzi ya nkhope ndipo angaphatikizepo diso, khungu la nkhope, ndipo nthaŵi zina denga la mkamwa. Anthu omwe ali ndi vutoli amakhala ndi mwayi waukulu wokhala ndi melanoma yamaso ndi glaucoma. Nevus ya Ito ndi yofanana koma imakhudza madera osiyanasiyana a mitsempha.
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 imadziwikanso kuti malo aku Mongolia. Ndi mtundu wamba wa chizindikiro chobadwa chomwe chimawonedwa mwa ana obadwa kumene. Zimawoneka ngati zigamba zotuwa pakhungu kuyambira kubadwa kapena posakhalitsa. Zizindikirozi zimapezeka m'munsi kumbuyo ndi matako, ndipo mapewa ndi malo omwe amapezeka. Amapezeka kawirikawiri m'makanda aku Asia ndi Black, amakhudza anyamata ndi atsikana mofanana. Nthawi zambiri, amazimiririka okha akafika zaka 1 mpaka 6 ndipo nthawi zambiri safuna chithandizo chilichonse chifukwa nthawi zambiri amakhala opanda vuto.
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.
