発 疹(ほっしん)

ほっしん

noun

1. rash; skin eruption

Red spots, bumps, or irritation that appear on the skin, usually as a symptom of illness, allergy, or other medical condition.

Composed of 発(ほつ) (emit, develop) and 疹(しん) (rash). Can also be read はっしん, though ほっしん is more common in medical and everyday usage. The duplicate check flagged entry 20451 (発信(はっしん), transmission) as sharing the same kanji with a different reading — these are unrelated words.
