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 le...

Laser treatment of Ota nevi can be complicated, particularly in darker skin types, as there is a higher risk for adverse effects if the laser is not carefully employed. We report a case of successful treatment of an Ota nevus in a patient with Fitzpatrick skin type IV with the novel 532-nm solid-state picosecond laser after 2 treatments.

Nevus of Ota is a macular discoloration the face which most commonly found in Japanese and females are more affected than males. It first described by Tanino 1939, involves skin along distribution second division trigeminal nerve. Involvement palatal mucosa occurs rarely nevus Ota, it usually blends with oral typically irregular, undefined often present as mottled patch. We describe here case i...

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...

It is usually present at birth in the two thirds of patients who have ocular involvement.It is more common in females with 5% being bilateral.4 It was first described by Ota in 1939. It can be unilateral or bilateral. Exact etiology and pathology of NOO is not known. Unconfirmed hypothesis is that it represents melanocytes that have not migrated completely from the neural crest to the epidermis...
