TL;DR: Key Takeaways
- Cherry angiomas = bright red, smooth, dome-shaped, harmless
- Blanch (lighten) when pressed — the key benign sign
- Amelanotic melanoma is the dangerous mimic — pink, firm, doesn't blanch, grows
- BCC and SCC can also present as red bumps that bleed or don't heal
- Any red spot that grows, bleeds, or doesn't blanch needs evaluation

At a Glance
| Feature | Cherry Angioma | Amelanotic Melanoma / BCC / SCC |
|---|---|---|
| Colour | Bright cherry red to purple, uniform | Pink, red, or skin-coloured; sometimes mixed pigment |
| Shape | Round, dome-shaped, symmetric | Irregular, asymmetric, or rolled edges (BCC) |
| Size | 1–5 mm, stable | Often >5 mm at diagnosis, growing |
| Blanching when pressed | Lightens or disappears momentarily | Does not blanch — solid lesion |
| Texture | Soft, smooth | Firm, sometimes pearly (BCC) or scaly (SCC) |
| Bleeding | Only if scraped or injured | Bleeds spontaneously or with light contact |
| Change over time | Stable for years | Grows over weeks to months |
| Danger | None | Cancer — early detection is crucial |
How a Cherry Angioma Looks
- Bright cherry-red or purple dome on the skin
- Soft, smooth, easily compressible
- 1–5 mm in size, stable for years
- Blanches (lightens) when pressed with a fingertip or glass slide
- Usually multiple, often on the trunk, after age 30
How the Cancer Lookalikes Look
- Amelanotic melanoma — pink or red bump, firm, may grow over months, often mistaken for a pimple that won't heal
- Basal cell carcinoma — pearly pink papule with visible small blood vessels; may have a central crust or ulcer
- Squamous cell carcinoma — red scaly bump, often tender, sometimes ulcerated
- Pyogenic granuloma — fast-growing red bump that bleeds easily; benign but often biopsied to rule out cancer

The 5 Visual Clues Dermatologists Use
- Blanching test — true angiomas blanch; cancers and pyogenic granulomas do not
- Firmness — angiomas are soft; cancers are usually firm or pearly
- Growth — angiomas are stable; cancers grow
- Bleeding pattern — spontaneous bleeding is a red flag
- Surface — pearly (BCC), scaly (SCC), or smooth-and-pink (amelanotic melanoma)
Red-Flag Checklist
- A red bump that has grown over the last 1–3 months
- A red lesion that bleeds without being touched
- A 'pimple' or 'scab' that hasn't healed in 4+ weeks
- A pearly or translucent pink papule (suggests BCC)
- Any red spot that's firm, painless, and doesn't blanch — see a dermatologist within 2–4 weeks

Frequently Asked Questions
No — cherry angiomas are completely benign collections of small blood vessels. They become more common after age 30 and most adults have several. They have no malignant potential.
Cherry angiomas are bright red to purple, smooth, dome-shaped, 1–5 mm, and blanch (lighten) when pressed. Concerning red spots — amelanotic melanoma, BCC, or SCC — are usually irregularly shaped, may bleed spontaneously, grow over weeks to months, and do not fully blanch.
No. Cherry angiomas do not transform into skin cancer. However, a 'new red spot' could be an amelanotic melanoma or BCC rather than an angioma — so any non-classic red lesion deserves evaluation.
A subtype of melanoma that lacks pigment, appearing as a pink, red, or skin-coloured bump rather than a dark mole. It's commonly mistaken for a pimple, scar, or cherry angioma and is one of the most-missed forms of melanoma.
If it bleeds spontaneously, grows over weeks, has irregular borders, is firm rather than soft, doesn't blanch when pressed, or looks distinctly different from your other red spots — see a dermatologist or use AI screening.
