BCEM, also referred to as conjunctival hypermelanosis, complexion-associated melanosis, or racial melanosis, is a non-cancerous lesion of the conjunctiva that is more commonly found in dark-skinned individuals (over 90% of lesions are found in black persons and around 5% in white persons). [1]
Nevus of Ota is a hyperpigmentation [3] that occurs on the face, most often appearing on the white of the eye. It also occurs on the forehead, nose, cheek, periorbital region, and temple. [4] It was first reported by Masao Ōta of Japan in 1939. [5]

However, a melanocytic nevus is benign, and melanoma is malignant. Most melanocytic nevi never evolve into a cancer, with the lifetime risk for an individual nevus being 1 in 3000 for men and 1 in 11 000 for women. [5] Moreover, dermatologists have a standardized system for determining whether a skin lesion is suspicious for malignant melanoma.

[2] Histologically it is characterized by swollen, pale, polyhedral melanocytes, with pale cytoplasm and a central nucleus. [2] It is different to balloon cell melanoma, [3] which has larger nuclei and is structured like a melanoma. [1] It was first described by ...
