Abstract:
Nevus of Ota is a benign dermal melanocytosis, that involves facial skin as a macular discoloration, appearing as blotchy blue to blue gray. It involves the upper portion of the face, especially over the periorbital area. It also involves ocular structures such as episclera, sclera, conjunctiva, cornea, retina, uveal tract and also nasopharynx, auricular mucosa, tymphanic membrane and dura. Glaucoma and malignant melanoma are the two known ocular complications in patients with Nevus of Ota. 12-18% of these patients exhibits palatal pigmentation. Here we are reporting two cases of Oculodermal melanocytosis, one of which exhibited palatal pigmentation.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
