Dermatitis caused by Malassezia pachydermatis correlated to ovarian cyst
Keywords:
Bitch, Dermatitis, MalasseziosisAbstract
Malassezia pachydermatis is an opportunistic pathogen and in dogs the increased prevalence of this fungus is generally associated with a primary cause, resulting in dermatitis. This work aimed to report the case of a dog with a recurrence of Malassezia pachydermatis, correlated to the simultaneous occurrence of ovarian cysts, addressing the clinical aspects, diagnosis, and animal treatment. An 8-year-old Golden Retriever dog, with a body weight of 35kg, not castrated, presented itching and erythema on some parts of the body, mainly on the snout, ears, and paws. The dog was active, eating, drinking, and playing normally. Moreover, it was also reported that the dog was going into heat approximately every 4 months, being diagnosed with an ovarian cyst through ultrasound imaging. The diagnosis was made based on cytological examination, fungal culture, and skin scrapings, where the exacerbated presence of malasseziosis was confirmed. Ovarian hysterectomy surgery was performed and treatment for malasseziosis consisted of systemic and topical antifungals. The result was positive with no recurrence after 9 months. The dog showed excellent recovery during the treatment period and due to the non-occurrence of recurrence, it is assumed that immunosuppression could be caused by irregular heats as a result of some hormonal disorder. It was concluded that it is important to carry out additional tests so that the best treatment for each disease can be instituted.
