Purpose of the Study:

To review the characteristics of pyoderma gangrenosum.
To discuss diagnostic challenges and treatment strategies.

Diagnosis relies on clinical presentation and exclusion of other ulcerative causes.

Mild cases may respond to local treatment; severe cases require systemic immunosuppressants.

Conclusions:

Pyoderma gangrenosum management requires a multidisciplinary approach.
Long-term immunosuppression may be necessary but carries risks of adverse effects.
