Which diagnosis is associated with vesiculopapular eruption over clothed areas in a hot environment?

• A. Heat Rash
• B. Heat Edema
• C. Heat Stroke
• D. Heat Cramps

Answer: (A)

Heat rash, or miliaria, arises when sweat ducts become blocked in hot, humid conditions, especially in areas covered by clothing where sweat is trapped. The blocked ducts cause sweat to leak into the skin, producing a vesiculopapular eruption in those covered regions. This presentation is distinctive from other heat-related problems: edema is simply swelling without vesicles, heat stroke involves dangerous hyperthermia with altered mental status, and heat cramps are painful muscle contractions due to electrolyte disturbances. So the vesiculopapular eruption in hot, clothed areas best fits heat rash.
