A seven-year-old female spayed Schnauzer was presented with cutaneous ulcerated nodular lesions shortly after the beginning of an immunosuppressive treatment for immune-mediated hemolytic disease. Cytology was performed and a great number of neutrophils and banana-shaped organisms were observed. Biopsy showed a neutrophilic and histiocytic dermatitis and panniculitis with myriads of intralesional bradyzoites cysts and tachyzoites. PCR analysis was positive for Toxoplasma gondii and negative for Neospora caninum. Immunohistochemistry confirmed intralesional T. gondii antigens. This study reports a rare case of cutaneous toxoplasmosis in an immunosuppressed dog.
