The hosts share key dermatology pearls essential for board exams, including distinguishing target lesions in various conditions, managing sebaceous cysts, recognizing vasculitis in children, and identifying necrotizing fasciitis and disseminated gonorrhea among dermatological conditions with vesicles.
Identifying target lesions in rashes can signify serious conditions like hypersensitivity reactions and Stevens-Johnson syndrome.
Distinguishing between infected and inflamed sebaceous cysts is crucial for proper management to prevent recurrence.

Rashes with target lesions - Pearls for Diagnosis
Identifying rashes with target lesions like those seen in erythema multiforme can indicate hypersensitivity reactions linked to infections and medications. Lyme disease and Stevens-Johnson syndrome are also associated with target lesions, with the latter progressing to mucosal involvement, distinguishing it as a medical emergency.
Managing sebaceous cysts involves distinguishing between infection and inflammation. Signs of infection like erythema and tenderness warrant incision and drainage (IND) with antibiotics, followed by referral to dermatology due to frequent recurrence. If no signs of infection are present, refrain from IND and refer the patient to dermatology for outpatient management to prevent recurrence.
Henoch-Schonlein Purpura - Classic Vasculitis in Children
Henoch-Schonlein Purpura (HSP) is a common childhood vasculitis presenting with palpable purpura on the lower limbs and abdomen pain, often triggered by viral infections. It manifests as IgA-mediated vasculitis and can lead to intussusception and nephropathy. Treatment typically involves supportive care and occasionally steroids for symptom management.
