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.
Signs and symptoms [ edit ] They appear as small, painless, raised, pale, red or white spots or bumps 1 to 3 mm in diameter that may appear on the scrotum, shaft of the penis , or on the labia , as well as the inner surface (retromolar mucosa) and vermilion border of the lips of the face .
A pilonidal cyst can resemble a dermoid cyst, a kind of teratoma (germ cell tumor). In particular, a pilonidal cyst in the gluteal cleft can resemble a sacrococcygeal teratoma. Correct diagnosis is important because all teratomas require consultation with an oncologist and complete surgical excision, if possible without any spillage.
Relative incidence of cutaneous cysts, where epidermoid cysts constitute a plurality (blue area). An epidermoid cyst or epidermal inclusion cyst [1] is a benign cyst usually found on the skin.
