Ota Nevus se yon nwasi benign nan po sitou alantou zòn nè trigeminal la, sitou ki afekte rejyon je yo sèvi pa premye ak dezyèm divizyon nè sa a. Kondisyon sa a, yo rele tou melanoz po okulè, lakòz yon dekolorasyon gri-ble akòz melanosit kwense. Li anjeneral parèt sou yon bò nan figi a epi li ka enplike je a, po figi, epi pafwa do kay la nan bouch la. Moun ki gen kondisyon sa a gen yon pi gwo chans pou yo devlope melanom je ak glokòm. Nevus nan Ito se menm jan an men afekte zòn nève diferan.
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 konnen tou kòm plas Mongolyen. Li se yon kalite mak nesans komen yo wè nan tibebe ki fenk fèt. Li parèt tankou plak gri-ble sou po a depi nesans oswa yon ti tan apre. Mak sa yo tipikman jwenn sou do a pi ba ak bounda, ak zepòl yo se pwochen kote komen an. Yo pi souvan nan ti bebe Azyatik ak Nwa, ki afekte tou de ti gason ak tifi egalman. Anjeneral, yo disparèt poukont yo nan laj 1 a 6 ane epi jeneralman yo pa bezwen okenn tretman paske yo sitou inofansif.
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.
