Endotriks tip kýl tutulumu bulunan bir tinea korporis olgusu

Dermatofitozlar, epidermisin stratum korneumunu, týrnaklarý ve kýllarý etkileyen, ölü keratin dokusunda yaþayabilen mantarlarýn enfeksiyonlarýdýr. Tinea korporis saçlý deri, sakal, el, ayak ve inguinal bölgeler dýþýndaki deride görülen yüzeyel dermatofit enfeksiyonudur. Burada, kýllarýn endotriks olarak etkilendiði bir tinea korporis olgusu sunulmaktadýr. Yirmi altý yaþýnda erkek hasta sol el sýrtý ve önkol dýþ yüzünde iki adet endüre plak nedeniyle baþvurdu. Alýnan skuamlardan yapýlan potasyum hidroksit (KOH) incelemesi negatif, ancak lezyon yerindeki kýllardan KOH incelemesi pozitif bulundu. Hasta sistemik terbinafin tedavisine iyi yanýt verdi. Klinik olarak tinea düþünülen hastalarda skuamdan direk KOH incelemesi negatif olursa lezyon yerindeki kýllardan inceleme yapmak tanýyý kolaylaþtýrabilir.

A case of tinea corporis with endothrix type hair involvement

Dermatophytoses are the infections of fungi which can live in dead keratin tissue and affect the stratum corneum of epidermis, nails and hairs. Tinea corporis is a superficial dermatophytosis which is seen in skin parts except hairy skin, beard, hand, foot and inguinal region. This report describes a tinea corporis case with endothrix type of hair involvement. A 26-year-old male patient referred for two indurated plaques on the dorsum of the right hand and the extensor surface of the forearm. A potassium hydroxide (KOH) analysis of lesional skin scrapings was negative, while the KOH analysis of the hairs was positive. The patient responded well to systemic terbinafine therapy. In patients who are considered clinically as tinea, if direct KOH analysis from skin scrapings is negative, examination of the hairs at the lesional area may facilitate diagnosis.
