Sažetak
Tinea incognita is a dermatophyte infection with atypical
clinical features modified by the improper use of corticosteroids or
calcineurin inhibitors. The aim of this study was to analyze clinical and
microbiological features of patients with tinea incognita. A total of
6326 patients referred to mycology laboratory between January 2008
and January 2011 for mycological examination with a diagnosis of
tinea incognita were reviewed retrospectively. Twenty-one patients,
13 (61.9%) women and 8 (38.1%) men, mean age 42.2±36.8, were
included in the study. Of them, lesions were localized in 15 (71.4%)
patients and widespread in six (28.6%) patients. The mean duration
of the disease was 9.5 (range 1-120) months. All patients had a history
of treatment with steroids. Before admission, most of them had
been misdiagnosed as eczema or psoriasis. Microscopic examination
revealed hyphae and spores in most of the cases (n=17, 80.95%).
Mycological cultures were positive in 19 (90.5%) patients. The most
frequently isolated dermatophyte was Trichophyton rubrum (n=14,
66.7%). This case series revealed Trichophyton rubrum as the most
frequent agent of tinea incognita. To the best of our knowledge, this
is the largest case series from Turkey describing clinical features and
mycological agents of tinea incognita.
