tinea versicolor; pityriasis versicolor

白癬 refers to ringworm (tinea) in general, while 癜 specifically refers to tinea versicolor, a superficial yeast infection causing discolored patches.
The kanji 癜 is composed of 疒 (sickness radical) and 殿, but the exact derivation is uncertain. The reading なまず is of native Japanese origin, likely referring to the patchy appearance of the skin.
