Chronic discoid or annular skin disorder – http://id.who.int/icd/entity/975730054
A provisional diagnosis for a chronic skin disorder of unknown or uncertain nature consisting 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.
