Q:
What is pigmented purpuric dermatosis?

A:
Pigmented purpuric dermatosis is a group of skin disorders which typically cause distinct reddish-brown rashes. They mainly appear on the lower limbs, and occasionally on the trunk.

These rashes can be either small or large. Anyway, they do not disappear with pressure.

Although the specific cause of this condition is unclear, researchers do regard the following things as risk factors:

  • Venous disease;
  • Capillary fragility;
  • Certain drugs;
  • Allergy to certain food coloring and dyes.

With respect to diagnosis, it requires a skin biopsy. Additionally, certain blood tests and allergy tests may be helpful to find the underlying condition. Once diagnosed, doctors will give various treatment options depending on the underlying condition.
