Amyloid-producing odontogenic tumor in a Shih-Tzu dog.
Department of Veterinary Pathology, College of Agriculture, Osaka Prefecture University, Sakai, Japan.
A 9-month-old male Shih-Tzu dog had a right mandibular tumor composed of strands, or nest-like proliferation of epithelial cells with abundant fibrous stroma characterized by spheroid to large nodular deposition of amyloid with Congo-red stain. Globule calcification was also seen throughout the tumor tissue and the spheroid depositions often had a concentrically laminated structure (Liesegang rings). The case was diagnosed as amyloid-producing odontogenic tumor in a dog.
