Ota nevus - Ота Невус
☆ Германаас гаргасан 2022 оны Stiftung Warentest-ийн үр дүнгээс үзэхэд ModelDerm-ийн хэрэглэгчдийн сэтгэл ханамж нь төлбөртэй телемедицинийн зөвлөгөө авахаас арай доогуур байв.
Энэ нь коньюнктивийн хэсэгт нөлөөлж болно.

Ota Nevus нь голчлон гурвалсан мэдрэлийн хэсгийн эргэн тойронд арьсны хоргүй харанхуй болох ба энэ мэдрэлийн нэг ба хоёрдугаар хэлтэст үйлчилдэг нүдний бүсэд голчлон нөлөөлдөг. Нүдний арьсны меланоз гэж нэрлэгддэг энэ эмгэг нь меланоцитүүд баригдсанаас болж саарал хөх өнгөтэй болдог. Энэ нь ихэвчлэн нүүрний нэг талд илэрдэг бөгөөд нүд, нүүрний арьс, заримдаа амны хөндийг хамардаг. Ийм өвчтэй хүмүүст нүдний меланома, глауком үүсэх магадлал өндөр байдаг. Итогийн невус нь ижил төстэй боловч өөр өөр мэдрэлийн хэсгүүдэд нөлөөлдөг.
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 монгол толбо ч гэж нэрлэдэг. Энэ нь шинэ төрсөн нярайд түгээмэл тохиолддог төрөлхийн тэмдэг юм. Энэ нь төрснөөс хойш эсвэл удалгүй арьсан дээр саарал хөх толбо хэлбэрээр илэрдэг. Эдгээр тэмдгүүд нь ихэвчлэн доод нуруу, өгзөг дээр байдаг бөгөөд мөр нь дараагийн нийтлэг байрлал юм. Ази болон хар арьст нялх хүүхдэд илүү их тохиолддог бөгөөд охид, хөвгүүдэд адилхан нөлөөлдөг. Ихэвчлэн 1-6 нас хүртэл өөрсдөө алга болдог бөгөөд ихэвчлэн ямар ч хор хөнөөлгүй байдаг тул ямар ч эмчилгээ хийх шаардлагагүй байдаг.
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.
