Nevus of Ota, a dermal melanocytic nevus, is rare in the Indian subcontinent. It presents as a brown, blue, or gray patch on the face and is within the distribution of the ophthalmic and maxillary branches of the trigeminal nerve. The oral cavity is infrequently involved in nevus of Ota. Only 11 cases have been documented in the English literature. We report a rare case of intraoral nevus of Ot...

Both acquired bilateral nevus of Ota-like macules (ABNOM) and nevus of Ota are characterized by the presence of dermal melanocytes. There are no differences in the method of treatment, however, postinflammatory hyperpigmentation (PIH) develops more often in ABNOM than in nevus of Ota following treatment. We investigated the differences in the development of PIH after treatment between ABNOM and...

absract intracranial invasion of cellular blue nevus (cbn) from the skin is extremely rare and such a condition with malignant transformation is even rarer. a case of meningeal melanoma with malignant transformation which was derived from an ota nevus is presented in this report. a21-year-old man with a neurocutaneous syndrome since childhood was referred with headache and mild left hemiparesia...

Nevus of Ota (nevus fuscoceruleus ophthalmomaxillaris) is a benign dermal melanocytic hematoma clinically appearing as a bluish-brown discoloration in the ophthalmic and/or maxillary branches of the trigeminal nerve. The condition first described by Ota and Tanino occurs predominantly in Asians with estimated frequency of 0.014% to 0.034%, but can be found in other ethnicities. Historical thera...

The nevus of Ota also known as "congenital melanosis bulbi" and "oculodermal melanocytosis" is a blue-gray hyperpigmentation that occurs on the face and eyes. The sclera is involved in two-thirds of cases (causing an increased risk of glaucoma). Women are nearly five times more likely to be affected than men. It is rare among Caucasian people. The nevus of Ota is congenital or acquired. Most ca...

A 41-year-old woman with a complex congenital nevus that possessed features of both a blue nevus and a nevus of Ota is described. She was found to have melanotic hyperpigmentation of the underlying subcutaneous tissue and dura mater. Two separate melanomas developed in the tissues underlying her nevus (one in the subcutaneous tissue and another intracranially, arising from the dura).

Melanomas arising from orbital melanocytic proliferations are exceedingly rare. Many questions remain regarding their development and malignant transformation. We report on a 45-year-old Caucasian woman with a nevus of Ota that presented with visual disturbances involving her right eye and was found to have a biopsy-proven cellular blue nevus in the orbital space. Five years later, she presente...

The purpose of this study is to evaluate the efficacy of Q-switched ruby laser in the treatment of nevus of Ota, a pigmented lesion on the face. The Q-switched ruby laser has been shown to remove tattoos without scarring. With this in mind, the nevus of Ota with pigmented cells in the dermis could be effectively treated with Q-switched ruby laser. Eighty patients (19 men, and 61 women) with nev...
