Orogenital ulcers of pyoderma gangrenosum resembling sexually transmitted disease

Area of Science:

• Dermatology
• Immunodermatology

Background:

• Pyoderma gangrenosum (PG) is a rare, non-infectious neutrophilic dermatosis.
• It can be idiopathic or associated with systemic conditions like inflammatory bowel disease and SLE.
• Orogenital ulcerations are a rare but challenging presentation of PG.

Observation:

• A patient presented with orogenital ulcers, initially suspected as a sexually transmitted disease (STD).
• The clinical presentation mimicked various STDs, complicating the initial diagnosis.
• Systematic exclusion of other conditions was necessary.

Findings:

• Laboratory results and histopathology confirmed the diagnosis of pyoderma gangrenosum.
• The case underscores the diagnostic challenges of PG presenting as orogenital ulcers.
• Differential diagnosis is crucial for appropriate management.

Implications:

• Accurate diagnosis of pyoderma gangrenosum is vital for effective treatment.
• Clinicians should consider PG in the differential diagnosis of orogenital ulcers, even when STDs are suspected.
• This case emphasizes the need for comprehensive evaluation to avoid misdiagnosis and delayed treatment.
