What to know about a black cherry angioma

A typical cherry angioma is a small red to purple vascular bump formed from closely grouped blood vessels. If it is rubbed, scratched, twisted, or develops a small clot, it may become purple-black or form a dark crust. That appearance can overlap with other pigmented or vascular lesions, so a photograph or description cannot confirm the diagnosis.

Clinicians assess the lesion's history, symmetry, border, colour pattern, surface, and behaviour. They may use a handheld magnifying instrument to inspect structures below the surface. If the diagnosis remains uncertain, sampling the lesion may be more appropriate than treating it cosmetically.

Avoid cutting, burning, squeezing, or tying off the growth yourself because vascular bumps can bleed and home treatment can hide useful diagnostic features. Protect it from repeated friction, and note when the dark colour appeared. A clear photograph beside a ruler can help document change while you arrange an examination.

If a clinician confirms a cherry angioma and it catches on clothing, bleeds repeatedly, or bothers you cosmetically, removal may be discussed. Options can include vascular laser treatment or electrosurgery; the choice depends on the lesion, its location, your skin, and the expected mark after healing.

Arrange a prompt skin examination if the spot is new and black, changes shape or colour, grows, develops an irregular border, becomes persistently sore, or bleeds without a clear injury. Seek urgent help if bleeding does not stop after firm continuous pressure, or if spreading redness, warmth, swelling, pus, or fever suggests infection.

Ask which examination features support cherry angioma and whether any feature calls for a sample before removal. If treatment is optional, discuss the likely scar or pigment change, wound care, bleeding control, and whether the whole lesion will be available for laboratory assessment. Mention any blood-thinning medicine before a procedure.
