Subcutaneous sarcoidosis with plantar involvement

Area of Science:

• Dermatology
• Rheumatology
• Pathology

Background:

• Sarcoidosis is a multisystem granulomatous disease with unknown causes.
• Subcutaneous sarcoidosis is an uncommon manifestation, with plantar involvement being exceptionally rare.
• Existing literature documents only one prior case of plantar sarcoidosis.

Observation:

• A patient presented with a diagnosis of subcutaneous sarcoidosis localized to the plantar aspect of the foot.
• The rarity of plantar sarcoidosis prompted detailed investigation and reporting.
• The patient's condition was successfully managed with intralesional corticosteroid injections.

Findings:

• The case confirms the possibility of subcutaneous sarcoidosis occurring on the plantar foot.
• Successful treatment was achieved using intralesional corticosteroids, suggesting a viable therapeutic option.
• This presentation adds to the limited case data for this rare sarcoidosis manifestation.

Implications:

• Highlights the importance of considering sarcoidosis in rare dermatological presentations, even in unusual locations.
• Demonstrates the efficacy of intralesional corticosteroid therapy for plantar sarcoidosis.
• Encourages further research into the pathogenesis and management of cutaneous sarcoidosis variants.
