Capillaritis is a harmless skin condition in which there are reddish-brown patches caused by leaky capillaries. It is also known as pigmented purpura.

The capillaries are small blood vessels near the skin surface. For unknown reasons they sometimes become inflamed, although a true vasculitis is not seen on skin biopsy. Blood cells may pass through small gaps that arise between the cells, which made up the capillary walls. The result is petechial haemorrhages. These fade away depositing haemosiderin in the upper parts of the dermis.

古籍记载：

Capillaritis is a collection of chronic disorders that simulate bruising; they are characterized by a perivascular lymphocytic infiltrate with endothelial swelling and consequent extravasation of red cells and subsequent haemosiderin deposition in macrophages.

Aetiology

These disorders have a bewildering nomenclature. Their cause is often obscure although gravity and increased venous pressure may be responsible for some and eczema for others. Morphologically similar eruptions have occurred secondary to drugs (carbromal, aspirin, paracetamol, thiamine and meprobamate) and clothing (khaki uniforms), Gravitational purpura is very similar.

Clinical Features

• Schamberg's disease (progressive pigmented purpura) This is more common in males and consists of irregular bruise-like patches of orange-brown discoloration with tiny petechiae (cayenne pepper spots) within them. They occur predominantly on the limbs, but may be seen elsewhere. They are remarkably chronic, although spontaneous cure does occur. A more acute short-lived pruritic condition of the lower legs and lower body is known as itching purpura (eczema-like purpura, Doucas and Kapetonakis disease) but its distinction from Schamberg's disease may be artificial.
• Pigmented purpuric lichenoid drmatosis of Gougerot and Blum Lichenoid papules occur in addition to the changes described in Schamberg's disease. It may well represent the same condition.
• Lichen aureus This is a localized rust-coloured solitary lesion that may persist for years and resembles a bruise. The petechiae are slightly raised and lichenoid.
