Atypical midface tumor complicating nevus of ota.
(9/23)
In the differential diagnosis of midface masses, the nevus of Ota (also called oculodermal melanocytosis) is a rare entity. We present a case of a young white man, who lost his left eye function by progression of a melanocytotic lesion involving the ophthalmic (VI) and maxillary (VII) divisions of the trigeminal nerve. The time course, distribution along the trigeminal nerve, and characteristic MR signal intensities of the lesion, in correlation with the clinical, ophthalmological, and dermatological findings, point to the correct diagnosis.

Acquired bilateral nevus of Ota-like macules.
(10/23)
A 41-year-old woman presented with a 10-year history of grey-brown macules bilaterally on lateral forehead, temples, and malar aspects. Histopathologic examination showed dermal melanocytosis. Acquired bilateral nevus of Ota-like macules (Hori's nevus) is a condition usually found in middle-aged women of Asian descent. Pathogenesis is unknown, and effective treatment has been achieved with pigment-specific lasers. (+info)
Bilateral nevus of Ota in a light-skinned woman.
(11/23)
Nevus of Ota is a dermal melanocytosis, clinically localized on skin that is innervated by the first and second branches of the trigeminal nerve. It occurs almost entirely in Asian people. This manifestation is rarely described in light-skinned non-Asian persons. We present a case of bilateral Ota nevus in a 47-year-old light-skinned non-Asian woman. (+info)
Nevus of Ota: a series of 15 cases.
(12/23)
BACKGROUND: The nevus of Ota is a dermal nevus characterized by bluish pigmentation in the distribution of the first and the second division of the trigeminal nerve. AIM: Our aim was to study the cutaneous and extracutaneous manifestations of the nevus of Ota. METHODS: A total of 15 cases were included in our study. A detailed history, clinical examination along with direct ophthalmoscopy and otoscopy were done for all the cases. RESULTS: Most of the patients (60%) had lesions at birth and the majority (86.7 %) were females. Five (33.3%) patients belonged to Tanino class II. Combined dermal and ocular involvement was observed in 60% of the cases. CONCLUSION: Tanino class II was the most common type observed in our studies. A few rarer associations such as nevus of Ito and hemangioma were also noted in our patients. (+info)
The additive influence of nevus flammeus and the nevus of Ota on congenital glaucoma.
(13/23)
Nevus flammeus and nevus of Ota are commonly encountered dermatological conditions, but both individually, are only occasionally associated with glaucoma. The occurrence of isolated nevus flammeus along with nevus of Ota in the same patient is also extremely rare. We are presenting two unusual cases, both having a nevus of Ota, together with nevus flammeus and severe congenital glaucoma. (+info)
