dyshidrosis; pompholyx
Medical term for a skin condition with small blisters on the hands or feet. Not the same as athlete's foot (水虫), though the English gloss includes it; athlete's foot is a fungal infection, while 汗疱 is a form of eczema.
Dyshidrosis is a skin condition where small blisters appear on the palms or soles.
Standard medical kanji spelling.
Irregular kanji usage; 泡 means 'bubble', which is not standard for this condition.
From 汗 (sweat) and 疱 (blister), reflecting the appearance of sweat-related blisters, though the condition is not directly caused by sweating.
