Nevus of Ota is a blue hyperpigmentation that occurs on the face, most often appearing on the white of the eye. It also occurs on the forehead, nose, cheek, periorbital region, and temple.
I- Ota Nevus iwukuba mnyama okungenabungozi kwesikhumba ikakhulukazi endaweni yemizwa ye-trigeminal, okuthinta kakhulu izifunda zamehlo ezihlinzekwa yizigaba zokuqala nezesibili zale nerve. Lesi simo, esibizwa nangokuthi i-ocular dermal melanosis, sidala ukushintsha kombala okumpunga noluhlaza okwesibhakabhaka ngenxa yama-melanocyte avaleleke. Ngokuvamile ivela ohlangothini olulodwa lobuso futhi ingase ihlanganise iso, isikhumba sobuso, futhi ngezinye izikhathi uphahla lomlomo. Abantu abanalesi simo banethuba eliphezulu lokuthuthukisa i-melanoma yamehlo kanye ne-glaucoma. I-Nevus ye-Ito iyafana kodwa ithinta izindawo ezihlukene zemizwa. 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 yaziwa nangokuthi indawo yaseMongolia. Iwuhlobo oluvamile lophawu lokuzalwa olubonwa ezinganeni ezisanda kuzalwa. Ibonakala njengamabala ampunga-luhlaza esikhumbeni kusukela ekuzalweni noma maduze nje. Lezi zimpawu zivame ukutholakala emhlane ongezansi nasezinqeni, amahlombe abe yindawo elandelayo evamile. Zivame kakhulu ezinsaneni zase-Asia naseMnyama, zithinta abafana namantombazane ngokulinganayo. Imvamisa, ziyanyamalala zodwa lapho eneminyaka engu-1 ukuya kweyisi-6 futhi ngokuvamile azidingi noma yikuphi ukwelashwa njengoba zingenabungozi. 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.
