☆ Tamin'ny valin'ny Stiftung Warentest 2022 avy any Alemaina, ny fahafaham-pon'ny mpanjifa amin'ny ModelDerm dia ambany kely noho ny fifampidinihana telemedicine karama.
Mety hisy fiantraikany faritra conjunctiva izany.

Ny Ota Nevus dia fahamaizinana tsara amin'ny hoditra indrindra manodidina ny faritry ny nerve trigeminal, izay miantraika amin'ny ankamaroan'ny faritry ny maso karakarain'ny fizarana voalohany sy faharoa amin'ity nerve ity. Ity toe-javatra ity, antsoina koa hoe melanose dermal ocular, dia miteraka loko volondavenona-manga noho ny melanocytes voafandrika. Matetika izy io no miseho amin'ny ilany iray amin'ny tarehy ary mety ahitana ny maso, ny hoditry ny tarehy, ary indraindray ny tafon'ny vava. Ny olona manana io aretina io dia manana vintana ambony kokoa amin'ny fivoaran'ny melanoma sy ny glaucome. Ny Nevus of Ito dia mitovy saingy misy fiantraikany amin'ny faritra nerveuse samihafa.
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 dia fantatra koa amin'ny hoe toerana Mongoliana. Karazana marika mahazatra hita amin'ny zaza vao teraka izany. Miseho toy ny tasy volondavenona manga eo amin’ny hoditra hatrany am-bohoka na fotoana fohy aorian’izay. Ireo marika ireo dia hita matetika eo amin'ny lamosina ambany sy ny vodiny, ary ny soroka no toerana mahazatra manaraka. Matetika kokoa izy ireo amin'ny zaza Aziatika sy Mainty, izay misy fiantraikany mitovy amin'ny ankizilahy sy ankizivavy. Amin'ny ankapobeny dia levona ho azy izy ireo amin'ny faha-1 ka hatramin'ny 6 taona ary amin'ny ankapobeny dia tsy mila fitsaboana satria tsy mampidi-doza ny ankamaroany.
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.
