Abstract

Two cases of canine dermatophytic pseudomycetoma resulting in subcutaneous nodules resembling those previously reported in Persian cats are described. Culture performed from one nodule yielded dark yellow colonies consistent with Microsporum canis. Immunohistochemistry, using rabbit anti-M. canis, demonstrated specific binding to fungal elements in paraffin sections. The specificity of the antiserum was further tested by an agar gel immunodiffusion assay using a soluble extract from a feline isolate of M. canis as antigen. The antiserum did not cross-react with an Aspergillus fumigatus antigen. These are the first two reported cases of canine dermatophytic pseudomycetoma and immunohistochemical staining supported the diagnosis.
