ABSTRACT
An Oldenburg colt with wry nose was autopsied after having lived for only 30 min. It presented cyanotic oral mucosae, underdeveloped eyes and a right-sided temporal osseous mass. The applicable nomenclature for the defects is discussed, and the potential etiopathogenesis is explored by describing the normal embryonic development of the affected body parts.

Peripheral odontoma is rare, and only two cases of congenital peripheral odontoma have been reported. Congenital oral fibroma is also rare. We describe a unique case of congenital peripheral developing odontoma accompanied by congenital teratomatous fibroma in an infant. Both tumors were difficult to detect on radiography. Two small masses were seen in the median anterior portion of the palatal mucosa of a 9-month-old boy. The masses had been present since birth and were surgically removed at age 28 months, when one of the masses had grown to a diameter of 8 mm. Histopathologic examination showed a fibrous lesion and a tooth germ-like rounded lesion composed of dental papilla, enamel organ, dentin, and cementum. Although congenital odontoma is rare, it should be considered when selecting appropriate treatment, as early radiographic detection is difficult.

Equine congenital dental deformities are not limited merely to those presented here; however, the examples discussed offer the reader an appreciation for the range of severity and complexity that may be found in affected horses. The veterinarian is obligated to provide the best possible care for the patient and to relieve animal suffering. The lack of definitive evidence for heritability of many of these defects can place the veterinarian in an untenable position, particularly when presented with literature that proclaims or suggests without evidence that a particular condition is inherited. In such cases, the veterinarian is encouraged to counsel owners, citing substantiated medical information, and to recommend that owners make the decision to eliminate the affected animals' ability to reproduce.
