Putative paraneoplastic pemphigus in a dog: clinical and microscopic findings

Abstract

In this case report, a dog with clinical and histopathological features of paraneoplastic pemphigus is described. A Lhasa apso with severe ulcerative oral and predominant facial skin disease had a thoracic mass histopathologically diagnosed as a thymoma. A concurrent disease-association was suspected. Cytologic examination of the oral lesions provided early clues to the dog’s ulcerative condition.
