Ota Nevus چمڙي جو هڪ ٻرندڙ اونداهي آهي خاص طور تي ٽريجيمنل اعصاب واري علائقي جي چوڌاري ، گهڻو ڪري اکين جي انهن علائقن کي متاثر ڪري ٿو جيڪو هن اعصاب جي پهرين ۽ سيڪنڊ ڊويزن طرفان ڪم ڪيو ويندو آهي. اها حالت، جنهن کي اوڪيولر ڊرمل ميلانوسس پڻ سڏيو ويندو آهي، ڦاٿل ميلانوسائٽس جي ڪري هڪ ڳاڙهي-نيري رنگت جو سبب بڻجي ٿو. اهو عام طور تي منهن جي هڪ پاسي تي ظاهر ٿئي ٿو ۽ اکين، منهن جي چمڙي، ۽ ڪڏهن ڪڏهن وات جي ڇت شامل ٿي سگھي ٿي. هن حالت سان ماڻهن کي اکين جي ميلانوما ۽ گلوڪوما جي ترقي جو وڌيڪ امڪان آهي. Ito جو Nevus ساڳيو آهي پر مختلف اعصاب علائقن کي متاثر ڪري ٿو.
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 منگولين اسپاٽ جي نالي سان پڻ سڃاتو وڃي ٿو. اهو هڪ عام قسم جو جنم نشان آهي جيڪو نون ڄاول ٻارن ۾ ڏٺو ويندو آهي. اهو ڄمڻ کان يا ٿوري دير کان پوءِ چمڙيءَ تي ڳاڙهي-نيري پيچ وانگر ظاهر ٿئي ٿو. اهي نشان عام طور تي هيٺين پٺي ۽ بتن تي مليا آهن، ڪلهن سان گڏ ايندڙ عام جڳهه آهي. اهي ايشيائي ۽ ڪاري ٻارن ۾ وڌيڪ اڪثر آهن، ٻنهي ڇوڪرن ۽ ڇوڪرين کي هڪجهڙائي سان متاثر ڪن ٿا. عام طور تي، اهي 1 کان 6 سالن جي عمر ۾ پنهنجو پاڻ تي ختم ٿي ويندا آهن ۽ عام طور تي ڪنهن به علاج جي ضرورت ناهي ڇو ته اهي گهڻو ڪري بي ضرر آهن.
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.
