Cutaneous toxoplasmosis in an immunosuppressed dog

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 intralesion...

Cutaneous manifestations of disseminated toxoplasmosis in an immunosuppressed dog.

A 3.5-year-old, castrated male, giant schnauzer was presented with alopecic pustular dermatitis. Immune-mediated hemolytic anemia had been diagnosed 45 days previously. At the time of presentation, the dog was receiving prednisone, azathioprine, and cyclosporine. Cutaneous protozoosis was diagnosed, and postmortem examination revealed protozoa within cutaneous, cardiac, pancreatic, and pulmonar...

Disseminated porokeratosis in immunosuppressed patients.

More than a century ago, two Italian dermatologists independently described a new keratotic disorder [1,2] which was called porokeratosis by Mibelli [1]. After these first descriptions, at least four variants of porokeratosis have been recognized. Clinically all these dermatological disorders are characterized by diffuse annular lesions surrounded by a raised, sharply marginated, keratotic bord...

Fungal Infections in Immunosuppressed Patients

Fungal infections, also called mycoses, are important causes of morbidity and mortality in humans. Some fungal infections are endemic, and these infections are usually caused by fungi that are present in the environment and whose spores enter humans. Other fungal infections are said to be opportunistic because the causative agents cause mild or no disease in healthy individuals but may infect a...
