Bizarre annular lesion emerging as tinea incognito

Mycoses. 2004 Oct;47(9-10):447-9. doi: 10.1111/j.1439-0507.2004.01021.x.

Abstract

Tinea incognito has first been described in 1968. The term describes a tinea infection whose clinical morphology has been modified by the application of topical corticosteroids. The clinical manifestation can masquerade a number of other dermatoses and leads to misdiagnosis of annular eruptions. We describe a patient who showed a bizarre appearance of annular, inflammatory skin lesions at the umbilical region. Mycological culture yielded Microsporum canis.
