ReferencesOta Nevus は、主に三叉神経領域周囲の皮膚にできる良性の黒ずみで、特にこの神経の第1部門と第2部門が支配する眼の領域に影響します。この状態は眼の真皮メラノーシスとも呼ばれ、閉じ込められたメラノサイトが灰青色の変色を引き起こします。通常は顔の片側に現れ、目や顔面の皮膚、場合によっては口蓋にも見られます。この症状がある人は、眼黒色腫や緑内障を発症しやすくなります。伊藤母斑は似ていますが、影響する神経領域が異なります。
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 は蒙古斑とも呼ばれます。新生児によく見られるあざです。出生時または生後間もなく、皮膚に灰青色の斑点として現れます。これらは通常、腰や臀部に見られ、次いで肩に現れます。アジア系と黒人の乳児でより頻繁に発生し、男子も女子も同様に影響を受けます。通常、1〜6歳までに自然に消失し、ほとんど無害なので治療は不要です。
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.
