[Pyoderma gangrenosum after orthopedic conservative treatment]

Area of Science:

• Dermatology
• Immunology
• Gastroenterology

Background:

• Pyoderma gangrenosum (PG) is a rare, ulcerative neutrophilic dermatosis.
• Often associated with immune dysfunction and triggered by minor trauma (pathergy).
• Ulcerative colitis is an associated immune-mediated condition.

Observation:

• A patient with ulcerative colitis developed PG.
• The PG manifested at the site of an iontophoresis patch used for tendinopathy.
• The condition required specialized care in a burn center.

Findings:

• Successful management involved corticosteroid therapy and adapted local wound care.
• Prompt differentiation from infectious causes like necrotizing fasciitis is crucial.
• PG is a diagnosis of exclusion requiring careful assessment.

Implications:

• This case underscores the importance of considering PG in patients with immune dysfunction and specific triggers.
• Multidisciplinary management is essential for rare and complex dermatological conditions like PG.
• Early and accurate diagnosis, alongside appropriate treatment, can lead to favorable outcomes and prevent severe sequelae.
