Urticaria Pigmentosa Due to Infection in a Sphynx Cat – Case Report

Abstract

A two- year-old Sphynx cat, an unneutered female with multiple erythematous papules with hyperpigmentation was presented. In skin biopsy, in the dermis, well differentiated monomorphic mast cells were found. Fungal culture was positive for Microsporum canis. Diagnosis of urticaria pigmentosa following M. canis infection was made. The animal was successfully treated with itraconazole orally and shampoo containing chlorhexidine and miconazole. To the authors’ knowledge, this is the first reported case of urticaria pigmentosa following the dermatophyte infection in a Sphynx cat.

Na pregled je primljena mačka, rase sfi nks stara dve godine, nekastrirana sa simptomima multiplih eritematoznih papula sa hiperpigmentacijom. Biopsijom kože, u dermisu uočene su jasno diferentovane monomorfne mast ćelije. Na kulturi za gljivice, uzorak je bio pozitivan na Microsporium canis. Postavljena je dijagnoza - urticaria pigmentosa kao posledica infekcije sa M. canis. Životinja je uspešno tretirana itrakonazolom (oralno) kao i sa šamponom koji je sadržavao hlorheksidin i mikonazol. Prema saznanju autora, radi se o prvom prikazanom slučaju “pigmentisane urtikarije”, nastale usled infekcije sfi nks mačke dermatofi tom.
