Tinea manuum misdiagnosed as psoriasis vulgaris: A case of tinea incognito
نویسندگان
چکیده
Tinea manuum is a fungal infection of the hands caused by dermatophytes. It can present with erythema and minimal scale on the dorsum of the hand. However, chronic tinea manuum lesions located on the palmar region may be scaly and hyperkeratotic. Tinea manuum usually affects the dominant hand but it can also occur bilaterally. The term ‘tinea incognito’ is used to describe a dermatophyte infection with altered morphology. Tinea incognito usually occurs after inappropriate treatment with topical steroids. Wood’s lamp examination, mycological culture, direct microscopy and molecular tehniques like polymerase chain reaction are the methods to reach a definitive diagnosis [1]. Dermatophyte infections can be managed with antifungal and keratolytic agents [2]. CASE REPORT
