Plain-English summary

A cat was brought to the vet because it was having trouble breathing and had a swollen, ulcerated bump on its nose. Tests showed that the bump was caused by a rare fungal infection from a type of fungus called Cladophialophora bantiana. The cat received antifungal treatment, but unfortunately, it had two relapses of the infection. The vet suspects that the infection might have started from a wound, even though the owner didn't notice any trauma.

Abstract

A case of feline cutaneous phaeohyphomycosis due to Cladophyalophora bantiana is described. The cat was presented with breathing difficulty and a swollen, ulcerated nodule on the dorsal nose and left nostril. Histological examination of the nodule revealed a cystic granulomatous dermatitis characterised by neutrophils, macrophages and giant cells. Pigmented, yeast-like fungus cells and hyphal elements were easily identified in haematoxylin-eosin stained tissue sections. Cladophyalophora bantiana was isolated from a tissue specimen. This organism, primarily known to cause cerebral infection in humans and cats, only rarely causes cutaneous infection. Despite anti-fungal chemotherapy two relapses occurred. The cat was feline immunodeficiency virus- and feline leukemia virus-negative and even if the owner was unaware of trauma, the hypothesis of wound contamination is the most likely.
