Capillaritis
Capillary system
Specialty	Dermatology
Symptoms	Small red and brown dots, or patches of red and brown
Duration	Weeks to months

It may occur in the lungs as pulmonary capillaritis,^[3] or in the skin as pigmented purpuric dermatosis. Capillaritis usually affects otherwise healthy people.

Capillaritis can take many forms but is made up of tiny red or brown dots that may be spread out or in a group forming a red or brown patch on the skin. One variation, Majocchi purpura, forms concentric rings.^[2]

Capillaritis is a mild condition not requiring treatment. There is no known cure, however capillaritis can disappear within a few weeks, recur from time to time, or persist for years.^[2]
