Halo nevus is a mole that is surrounded by a pale ring or 'halo'. [1] It is generally noticed in the summer, when surrounding skin tans, and usually occurs on the chest, but can be anywhere. [ 1 ] There may be one or, more typically, several. [ 2 ]
A spider angioma or spider naevus (plural: spider naevi), also nevus araneus, is a type of telangiectasis [2] (swollen, spider-like blood vessels on the skin) found slightly beneath the skin's surface, often containing a central red spot and deep reddish extensions (see Blood color) which radiate outwards like a spider's web or a spider's legs.
The CDKN2A gene is located on chromosome 9p21.3. Two main transcripts, isoforms '1' and '4', each contain three exons and span 7288 and 26740 bp, respectively. They encode proteins of 156 and 173 amino acids; isoform '1' encodes p16(INK4a), while isoform '4' encodes p14(ARF), a protein that is structurally unrelated to p16(INK4) but acts in cell cycle G1 control by stabilizing the tumor ...
Cherry angioma, also called cherry hemangioma [1] or Campbell de Morgan Spot, [2] is a small bright red dome-shaped bump on the skin. [3] It ranges between 0.5 – 6 mm in diameter and usually several are present, typically on the chest and arms, and increasing in number with age.

An infantile hemangioma (IH), sometimes called a strawberry mark due to appearance, is a type of benign vascular tumor or anomaly that affects babies. [1] [2] Other names include capillary hemangioma, [6] "strawberry hemangioma", [7]: 593 strawberry birthmark [8] and strawberry nevus.
A dysplastic nevus or atypical mole is a nevus (mole) whose appearance is different from that of common moles. In 1992, the NIH recommended that the term "dysplastic nevus" be avoided in favor of the term "atypical mole". [1]
Nevus (pl.: nevi) is a nonspecific medical term for a visible, circumscribed, chronic lesion of the skin or mucosa. [1] The term originates from nævus, which is Latin for "birthmark"; however, a nevus can be either congenital (present at birth) or acquired.
