Early onset sarcoidosis: not a benign disease

Area of Science:

• Pediatrics
• Rheumatology
• Ophthalmology

Background:

• Childhood sarcoidosis has two distinct forms.
• Early-onset sarcoidosis affects children under four years old.
• This form differs in racial demographics from adult sarcoidosis.

Observation:

• Six patients with early-onset sarcoidosis were studied.
• The characteristic triad includes rash, arthritis, and uveitis.
• Symptoms align with existing literature.

Findings:

• Long-term follow-up (9-23 years) identified severe complications.
• Complications included blindness (4 patients), growth retardation (3), cardiac issues (2), renal failure (1), and death (1).
• Pulmonary involvement was rare and late-onset.

Implications:

• Early-onset sarcoidosis can be misdiagnosed due to rarity and similarity to juvenile arthritis.
• Distinct clinical features warrant careful differentiation.
• Prompt diagnosis is crucial for managing severe prognosis and exploring therapeutic options.
