Myxoid leiomyoma of the iris in a dog.
A leiomyoma of the iris is described in an 11-year-old Yorkshire Terrier. This is a rare primary intraocular tumor in dogs and we describe the clinical presentation, gross findings and histopathologic characteristics of this tumor. The diagnosis was made on the basis of light microscopy and immunohistochemical staining using antidesmin antibodies, which is specific for myogenic tissues. An unusual feature of the tumor was the presence of myxoid change. To our knowledge myxoid change has not been previously described in a primary intraocular leiomyoma.
