in some cases, involve unusual sites. Nevus of Ota is a permanent
unilateral congenital/aquired blue/gray patch on the face and it may

We present a five-months old dark-skinned female admitted in our clinic
for pneumonia and seizures. She is the third child of an young healthy
couple. The pregnancy was not followed up and she was delivered

buttocks. Right eye’s bulbar conjunctiva was also involved. The patchs
