Ota nevus
☆ Alemaniako Stiftung Warentest-en 2022ko emaitzetan, ModelDerm-ekin kontsumitzaileen gogobetetasuna apur bat txikiagoa izan zen ordaindutako telemedikuntzako kontsultekin baino.
Eremu konjuntiboari eragin diezaioke.

Ota Nevus larruazaleko iluntze onbera da, batez ere nerbio trigeminoaren inguruan, gehienbat nerbio honen lehen eta bigarren zatiek zerbitzatzen dituzten begien eskualdeei eragiten diena. Egoera honek, begiko dermal melanosis ere deitzen dena, kolore gris-urdina eragiten du harrapatuta dauden melanozitoen ondorioz. Normalean aurpegiaren alde batean agertzen da eta begia, aurpegiko larruazala eta, batzuetan, aho-sabaia izan ditzake. Egoera hau duten pertsonek begiko melanoma eta glaukoma garatzeko aukera handiagoa dute. Itoko neboa antzekoa da baina nerbio-eremu ezberdinei eragiten die.
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 Mongoliako leku gisa ere ezagutzen da. Jaioberrietan ikusten den jaiotza-marka mota arrunta da. Larruazalean adabaki gris-urdin gisa agertzen da jaiotzetik edo handik gutxira. Marka hauek normalean bizkarrean eta ipurmasailean aurkitzen dira, sorbaldak hurrengo kokapen arrunta izanik. Haur asiar eta beltzetan maizago dira, mutilei eta neskei berdin eragiten diete. Normalean, bere kabuz desagertzen dira 1 eta 6 urterekin eta, oro har, ez dute inolako tratamendurik behar gehienetan kaltegabeak baitira.
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.
