ReferencesNevus tarîbûnek bextewar a çerm e ku bi gelemperî li dora devera nerva trigeminal ve dîtine, û bandorê li herêmên çavan dike, ku ji hêla beşên yekem û duyemîn ên vê nervê ve têne xizmet kirin. Ev rewş, ku jê re melanosisê çermê çavan jî tê gotin, ji ber melanocîtên girtî dibe sedema rengê gewr‑şîn. Ew bi gelemperî li aliyekî rûyê xuya dibe, û dikare li çav, çermê rû, û carinan jî li banê devê xwe xuya bibe. Kesên bi vê nexweşiyê re şansê pêşkeftina melanoma û glaucoma‑ya çavan heye. Nevus of Ito dişibe, lê bandorê li deverên cûda yên nervê dike.
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 (deqê mongolî) jî tê zanîn. Ew celebek gelemperî ya jidayikbûnê ye ku di nav zarokên nûbûyî de tê dîtin. Ew ji jidayikbûnê an piştî demek kin ve li ser çerm wekî pişkên gewr‑şîn xuya dike. Van nîşanan bi gelemperî li ser pişta jêrîn û qûnê têne dîtin, ku milên wan cîhê hevpar ên din in. Ew di pitikên Asyayî û Reş de pirtir in, hem li kur hem keçan wekhev bandor dikin. Bi gelemperî, ew di temenê 1‑6 saliyan de bi tenê serê xwe winda dibin û bi gelemperî hewceyê dermankirinê ne, ji ber ku ew bi piranî bêzerar in.
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.
