Successful treatment of pyoderma gangrenosum in a patient winh ulcerative colitis and COVID-19 infection: case report

Pyoderma gangrenosum is a rare inflammatory neutrophilic dermatosis, which causes ulceration of the skin. The condition is commonly associated with underlying systemic disorders such as inflammatory bowel disease, arthritis, and hematological disorders. Herein, we describe the case of a familiar association between pyoderma gangrenosum and ulcerative colitis complicated by the newly COVID-19 infection.

It is of particular clinical interest to address pyoderma gangrenosum lesions with concurrent treatment of associated disorders that may have influence on the course of the ulcer. Moreover, the therapy should cover as many diseases as possible while not being excessive to minimize possible side effects.

Thus, the selection of treatment that spans mutual pathophysiological features of all comorbidities represents the best option to make when handling pyoderma gangrenosum patients.

We present a case of the development of gangrenous pyoderma against the background of ulcerative colitis complicated by the new coronavirus infection COVID-19, which will raise awareness of gangrenous pyoderma as a relatively rare cause of ulcerative necrotic skin lesions, which can easily be confused with an infectious process.

Of particular clinical importance in the conditions of the COVID-19 pandemic is the correct treatment of gangrenous pyoderma. Only an integrated approach can give a positive result from the therapy.
