Cally, a 10 year old domestic cat, presented with thick crusts around the right ear pinna (the ear flap). She had initially been sent for assessment for possible surgery to the right ear canal, but the surgeons took a biopsy and “bounced” her to Roger, our dermatologist.
The pathology report showed a heavy local mite infestation and a heavy Malasezia yeast infection. Immune deficiency was suspected and the case will be managed medically rather than surgically.
We think that the mites are Sarcoptes scabei, a pretty unusual finding.
