Can compound nevus turn into melanoma?

Yes — but most dysplastic nevi do not turn into melanoma. Most types of atypical moles remain stable over time. Patients with five or more dysplastic nevi are 10 times more likely to develop melanoma than individuals with no atypical moles.

What does compound melanocytic nevus mean?

Compound Nevi are a sub-class of Common Acquired Melanocytic Nevi. Typically they are light tan to dark brown, dome shaped papules that are 1-10 mm in diameter. Compound Nevi are benign proliferations of melanocytes at the epidermal-dermal junction.

What is the cause of nevus of Ota?

Cause. Nevus of Ota is caused by the entrapment of melanocytes in the upper third of the dermis. It is found only on the face, most commonly unilaterally, rarely bilaterally and involves the first two branches of the trigeminal nerve. The sclera is involved in two-thirds of cases (causing an increased risk of glaucoma) …
