Capillaritis in Adult
Alerts and Notices
Synopsis
Several distinct clinical entities have been described:
- Schamberg disease: the most common manifestation of PPD
- Purpura annularis telangiectodes (Majocchi disease)
- Eczematid-like purpura of Doucas and Kapetanakis
- Pigmented purpuric lichenoid dermatosis of Gougerot and Blum
- Lichen aureus
- Linear pigmented purpura
- Granulomatous pigmented purpura
Capillaritis is typically asymptomatic but may be pruritic. It is usually a chronic condition with intermittent exacerbations and remissions. There is no geographic or hereditary population predilection. Men appear to be affected more commonly than women.
