Nevus of Ota: a series of 15 cases.

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.
