ReferencesOta Nevus تیره شدن خوش خیم پوست عمدتاً در اطراف ناحیه عصب سه‌قلوی است که بیشتر نواحی چشم را تحت تأثیر قرار می‌دهد؛ این عصب به دو بخش اول و دوم تقسیم می‌شود. این بیماری که ملانوز پوستی چشمی نیز نامیده می‌شود، به دلیل ملانوسیت‌های به دام افتاده باعث تغییر رنگ خاکستری مایل به آبی می‌شود. معمولاً در یک طرف صورت ظاهر می‌شود و ممکن است چشم، پوست صورت و گاهی سقف دهان را درگیر کند. افراد مبتلا به این بیماری شانس بیشتری برای ابتلا به ملانوم چشم و گلوکوم دارند. Nevus of Ito مشابه است اما نواحی عصبی متفاوتی را تحت تأثیر قرار می‌دهد.
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 همچنین به عنوان نقطه مغولی شناخته می‌شود. این یک نوع رایج خال مادرزادی است که در نوزادان مشاهده می‌شود. از بدو تولد یا کمی پس از آن به صورت لکه‌های خاکستری مایل به آبی روی پوست ظاهر می‌شود. این علائم معمولاً در ناحیه پایین کمر و باسن دیده می‌شوند و شانه‌ها مکان رایج بعدی هستند. آنها در نوزادان آسیایی و سیاه‌پوست بیشتر مشاهده می‌شوند و پسران و دختران را به‌طور مساوی تحت تأثیر قرار می‌دهند. معمولاً در سن ۱ تا ۶ سالگی خود به خود محو می‌شوند و نیازی به درمان ندارند زیرا عمدتاً بی‌ضرر هستند.
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.
