Brocq's geometric phagedena over penis with keloidal scars

Area of Science:

• Dermatology
• Immunology
• Pathology

Background:

• Pyoderma gangrenosum is a rare neutrophilic inflammatory skin disorder.
• It typically affects the lower limbs.
• Penile involvement is exceptionally rare.

Purpose of the Study:

• To report a rare case of pyoderma gangrenosum affecting the penile area.
• To describe the clinical presentation and healing characteristics.
• To highlight the occurrence in an immunocompetent individual without systemic disease.

Main Methods:

• Case report of a young man with ulcerative pyoderma gangrenosum on the penis.
• Documentation of concurrent pustular pyoderma gangrenosum elsewhere on the body.
• Observation of healing with keloid formation.

Main Results:

• Successful documentation of ulcerative pyoderma gangrenosum on the penis.
• Co-occurrence of pustular pyoderma gangrenosum.
• Healing of lesions with keloids observed.
• Absence of systemic associations or immunodeficiency.

Conclusions:

• Pyoderma gangrenosum can manifest rarely in the penile region.
• The condition can present with diverse morphologies (ulcerative and pustular).
• Healing may result in keloid scarring, even in immunocompetent individuals.
