Acne is a dermatological disorder that can be more commonly seen in adolescents as well as younger patients. The pediatric acne is classified according to the age groups as neonatal acne, infantile acne, mid-childhood acne, and prepubertal acne. The presentation, pathogenesis, differential diagnosis, and treatment of the disease vary in each age group. Early diagnosis is important to prevent the scar formation and determine the underlying abnormalities.

Behçet’s disease (BD) is a multisystemic vasculitis of unknown aetiology, initially reported by Turkish dermatologist Hulusi Behçet in 1937. Hulusi Behçet presented the disease as a triple symptom complex with recurrent aphthosis, genital ulceration and recurrent hypopyon uveitis. But subsequent studies have shown that it can affect many organs with wide clinical spectrum. It is challenging to make a definite diagnosis because there is no pathognomic laboratory test to diagnose Behçet’s disease. The diagnosis is based on variable group of clinical manifestations. Many new diagnostic/classification criteria have been developed through the years. International Study Group (ISG) Criteria and the International Criteria for Behçet’s Disease (ICBD) are the most commonly acceptable criteria for the diagnosis of BD. However, due to the broad clinical spectrum of Behçet’s disease, there will always be Behçet’s patients who do not complete the criteria. Therefore, the experience of the physician and evaluation of the findings with a good clinical anamnesis is of great importance in the diagnosis.
