Acute discoid or annular skin eruption – http://id.who.int/icd/entity/205263095
A provisional diagnosis for a skin eruption of unknown or uncertain nature which arises abruptly and consists of multiple circular or ring-shaped patches and plaques. Although infection due to dermatophyte infection (tinea or ringworm) can produce this pattern, many other skin disorders may have a discoid or annular configuration: these are frequently misdiagnosed as tinea. Common examples include atopic eczema, nummular dermatitis and psoriasis.
