Definition

Kerion is an erythematous, boggy, tender, often sterile, weeping nodule or plaque with pustules and draining sinuses. Hair in these areas appears lusterless, brittle, and is easily plucked. Kerion can be solitary or multiple but is usually unilateral. Patients with inflammatory tinea barbae may have constitutional symptoms like fever and malaise. Kerion is a coalesced sterile pustule, but occasionally they can get superinfected with cutaneous bacteria and develop regional lymphadenopathy. [from HPO]
