Summary
Multiple epulides, rare feline oral tumors, were diagnosed in 13 cats. These neoplasms frequently recurred after surgery but did not metastasize, indicating a need for careful monitoring.
Area of Science:
- Veterinary Pathology
- Oncology
- Feline Medicine
Background:
- Epulides are a type of feline oral neoplasm, typically occurring as single lesions.
- Previous literature reported no cases of multiple epulides in cats.
Purpose of the Study:
- To describe the clinicopathological features of multiple, concurrent epulides in cats.
- To assess the recurrence and metastatic potential of these feline oral tumors.
Main Methods:
- Histopathological examination of oral tumors from 13 cats diagnosed with multiple epulides.
- Review of clinical records for recurrence and metastatic data post-surgical excision.
Main Results:
- Multiple epulides were diagnosed in 13 cats, with fibromatous and ossifying types being most common (11/13).
- Microscopically, these were nonencapsulated, infiltrative neoplasms with spindle-shaped cells and osseous foci.
- Recurrence was observed in 8 of 13 cats following surgical removal; no metastatic cases were identified.
Conclusions:
- Multiple epulides in cats, though uncommon, present a significant challenge due to high recurrence rates.
- Despite their infiltrative nature, these feline oral tumors do not appear to have metastatic potential.

01:39Epistasis
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
01:58X-Inactivation
The human X chromosome contains over ten times the number of genes as in the Y chromosome. Since males have only one X chromosome, and females have two, one might expect females to produce twice as many of the proteins, with undesirable results.
