Papule
What is it?
A papule is a small, solid bump on the skin that you can both see and feel. These bumps are smaller than a pencil eraser (less than 1 centimeter) and rise above the skin surface. Unlike pimples with pus or blisters with fluid, papules are solid throughout. Think of them as tiny hills on your skin's landscape - they're the most common type of raised skin lesion.
What does it look like?
Papules can have various appearances:
- Small raised bumps, from pinpoint size to pencil eraser size
- Shape variations: Dome-shaped (smooth top), flat-topped, pointed, or warty surface
- Colors: Skin-colored, pink, red, purple, brown, or yellow
- Surface: Can be smooth, rough, or scaly
- Special features: Some have a central dent (umbilicated) like molluscum contagiosum
- Usually firm to touch, not soft or fluid-filled
- May occur alone or in groups
Where does it appear?
Papules can develop anywhere on the body:
- Face: Acne, flat warts, syringomas around eyes
- Hands and feet: Common warts, flat warts
- Arms and legs: Keratosis pilaris ("chicken skin"), lichen planus
- Trunk: Molluscum contagiosum, cherry angiomas
- Genital area: Pearly penile papules, genital warts
- Anywhere: Insect bites, drug reactions, skin tags
Associated features
Papules may be accompanied by:
- Itching (especially with eczema or lichen planus)
- Tenderness (inflamed acne papules)
- Surrounding redness or inflammation
- Gradual increase in number over time
- Changes in color or size
- Formation of groups or lines of papules
- Resolution leaving temporary marks
When to see a doctor
Seek medical evaluation for:
- Papules that are growing, changing color, or bleeding
- New papules appearing suddenly in large numbers
- Papules with irregular borders or multiple colors
- Painful or tender papules
- Papules that don't improve with over-the-counter treatments
- Genital papules or those in sensitive areas
- Any papules you're concerned about
