What causes nevus Spilus?
These discoveries indicate that nevus spilus is an expression of mosaicism through post-zygotic mutations in genes involved with the Ras pathway, and thus is an example of a mosaic RASopathy 10). Nevus spilus is a relatively uncommon skin lesion found in 0.2%-2.3% of the general population.
Can a birthmark turn cancerous?
Different types of birthmarks are made up of different types of cells. Most birthmarks, such as the common port wine stains and strawberry marks, carry no risk of developing into a cancer.

- Asymmetry. One part of a mole or birthmark doesn’t match the other.
- Border. The edges are irregular, ragged, notched, or blurred.
- Color. The color is not the same all over and may include shades of brown or black, sometimes with patches of pink, red, white, or blue.
- Diameter.
- Evolving.
How is a nevus removed?

Which dermatomes are involved in segmental nevus depigmentosus and segmental vitiligo?
Trunk (36.5%) and cervical (38.1%) dermatomes were the most commonly involved in segmental nevus depigmentosus and face (67.1%) and trigeminal (64.4%) dermatomes in segmental vitiligo. The average number of dermatomes involved in truncal lesions was different in segmental nevus depigmentosus and segmental vitiligo (2.71 vs 1.62, P = 0.001).
What is epidermal nevus syndrome?
