Symptoms of Pyoderma Gangrenosum

The main symptom of pyoderma gangrenosum is a large, painful ulcer on the skin. This ulcer usually begins as a small bump, spot or blood blister that quickly grows and forms into an ulcer.2 These ulcers most commonly affect the lower limbs but can also affect other areas of the body.3,4
Other symptoms of pyoderma gangrenosum can include2:
•    Stiff joints
•    Aching and muscle pain
•    A high temperature

Causes and prevalence of Pyoderma Gangrenosum

There are multiple causes of pyoderma gangrenosum including minor body trauma, systemic inflammatory disease, certain drugs and genetic risk factors.3,5
The disease can affect individuals of all ages but is most common in middle-aged adults.3 

Pyoderma Gangrenosum can significantly impact quality of life

The rapid and painful nature of this rare skin disease means that people living with pyoderma gangrenosum may face everyday life in constant fear of recurrence or disease worsening.1
