| The only lesion that does have cysts is lymphangioma, which could resemble a diffuse amelanotic naevus. |
| The blue naevus is a dark blue color because the color or pigment is deeper in the skin than in commoner brown moles and freckles. |
| The naevus is a discrete, flat or slightly elevated sessile lesion. |
| Choroidal naevus and congenital hypertrophy of the retinal pigment epithelium account for a high proportion of pigmentary lesions referred to secondary care. |
| Lisch nodules are pigmented hamartomatous naevus, which occur from proliferation of melanocytes and fibroblasts. |
| This technique can also be applied successfully to the treatment of various medical conditions of the skin of the face which are inappropriate for surgery, such as epidermal naevus. |
