Characteristic target-like skin lesions are observed in patients with:___________?
Show answer Hide answer
Answer: A. Erythema multiforme
Explanation
Erythema multiforme is characterized by distinctive target or iris skin lesions distributed symmetrically. These classic lesions feature concentric rings of color change with a central blister or erosion. The cutaneous eruption often accompanies painful oral mucosal erosions and ulcerations. The condition frequently represents an immune-mediated hypersensitivity reaction triggered by infections or drugs. Herpes simplex virus infection is the most common identifiable precipitating factor for this condition. Mild forms resolve spontaneously, while severe major variants can involve widespread cutaneous blistering.
Early recognition of target lesions helps clinicians identify and treat underlying infectious triggers. Supportive care with adequate hydration and topical pain management is crucial for oral lesions. Severe systemic manifestations require hospitalization and careful monitoring of fluid and electrolyte balance. Lichen planus features characteristic pruritic purple polygonal papules and fine white Wickham striae. Pemphigus vulgaris presents with fragile cutaneous blisters and positive Nikolsky signs due to acantholysis. Psoriasis manifests as chronic erythematous plaques covered by silvery-white scales on extensor surfaces.
