Ota nevus
☆ Ann an toraidhean 2022 Stiftung Warentest às a’ Ghearmailt, cha robh sàsachd luchd-cleachdaidh le ModelDerm ach beagan nas ìsle na le co-chomhairlean telemedicine pàighte.
Faodaidh e buaidh a thoirt air an raon conjunctival.

Tha Ota Nevus na dhorchachadh craiceann mì-rianail gu ìre mhòr timcheall air an raon nerve trigeminal, sa mhòr-chuid a’ toirt buaidh air roinnean na sùla air am frithealadh leis a’ chiad agus an dàrna roinn den nerve seo. Tha an suidheachadh seo, ris an canar cuideachd melanosis dermal ocular, ag adhbhrachadh dath liath-gorm mar thoradh air melanocytes glaiste. Mar as trice bidh e a’ nochdadh air aon taobh den aodann agus faodaidh e a bhith a’ toirt a-steach an t-sùil, craiceann aghaidh, agus uaireannan mullach a’ bheul. Tha cothrom nas àirde aig daoine leis a’ chumha seo melanoma sùla agus glaucoma a leasachadh. Tha Nevus of Ito coltach ri chèile ach a 'toirt buaidh air diofar raointean neònach.
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.

Tha Congenital dermal melanocytosis air ainmeachadh cuideachd mar àite Mongolianach. Is e seòrsa de chomharra breith cumanta a th 'ann a chithear ann an ùr-bhreith. Bidh e a’ nochdadh mar phìosan glas-ghorm air a’ chraiceann bho àm breith no goirid às deidh sin. Mar as trice lorgar na comharran sin air a’ chùl ìseal agus na cnapan, le guailnean mar an ath àite cumanta. Bidh iad nas trice ann am pàisdean Àisianach is Dubha, a’ toirt buaidh air balaich is nigheanan gu co-ionann. Mar as trice, bidh iad a’ seargadh air falbh leotha fhèin ro aois 1 gu 6 bliadhna agus sa chumantas chan fheum iad làimhseachadh sam bith oir tha iad gun chron sa mhòr-chuid.
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.
