A papule is a small, solid and usually conical elevation of the skin. Papules do not contain pus, which distinguishes them from pustules. Papules often occur in clusters and can accompany rashes.
A condition that causes a papule is called a "Papulosis". Examples of papuloses include:
- Lymphomatoid papulosis
- Bowenoid papulosis
- Clear cell papulosis
Causes
Papules can be caused by:
- Inflammation (which in turn is often caused by infection or abrasion of the skin)
- Accumulated secretion of skin tissue (hyperplasia) or glandular fluids.
- Presence of an infection such as disseminated histoplasmosis.
- Hypertrophy of skin cells
- Acne
