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.
Ota Nevus bubumnyama obungenabungozi bolusu ikakhulu obujikeleze indawo yemithambo-luvo ye-trigeminal, ikakhulu ichaphazela imimandla yeliso ebonelelwa licandelo lokuqala nelesibini lalo mthambo. Le meko, ikwabizwa ngokuba yi-ocular dermal melanosis, ibangela ukujika kombala ongwevu-blue ngenxa yeemelanocyte ezivalelekileyo. Ngokuqhelekileyo kubonakala kwicala elinye lobuso kwaye kunokubandakanya iliso, isikhumba sobuso, kwaye ngamanye amaxesha uphahla lomlomo. Abantu abanale meko banethuba eliphezulu lokuphuhlisa imelanoma yamehlo kunye neglaucoma. I-Nevus ye-Ito iyafana kodwa ichaphazela iindawo ezahlukeneyo zemithambo-luvo. 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 ikwabizwa ngokuba yindawo yaseMongolia. Luhlobo oluxhaphakileyo lweempawu zokuzalwa ezibonwa kwiintsana ezisanda kuzalwa. Ibonakala njengamabala angwevu-blue esikhumbeni ukususela ekuzalweni okanye kamsinya emva koko. La manqaku adla ngokufumaneka kumqolo osezantsi kunye neempundu, kunye namagxa ayindawo eqhelekileyo elandelayo. Zixhaphake kakhulu kwiintsana zaseAsia naseMnyama, zichaphazela amakhwenkwe namantombazana ngokulinganayo. Ngesiqhelo, ziye ziphele zodwa kwiminyaka e-1 ukuya kwi-6 kwaye azidingi naluphi na unyango njengoko 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.
Ukusetyenziswa kwe-Q-switched 1064 nm laser kuye kwabikwa ukuba kuphumelele ekuphatheni i-nevus ye-Ota.
