Extensive Pyoderma Gangrenosum: A Challenging Diagnosis and Literature Review of Management.

Pyoderma gangrenosum is a very rare, non-infectious leukocytic dermatosis, which is often associated with an underlying systemic disease. It is usually diagnosed based on the apparent clinical findings and by excluding other causes of ulcerative skin diseases. Treatment modality includes the use of systemic steroids and oral steroids. Immunosuppressive agents, such as cyclosporine and mycophenolate mofetil, can also be added if it fails to respond to steroids. We report a case of pyoderma gangrenosum in an 85-year-old female who presented in the inpatient facility with rapidly enlarging necrotic, ulcerative lesions with accompanying fever. She was managed with systemic steroids to which she responded well. This led to the arrest of the initially progressive lesions with some residual scarring.
