What is the diagnostic plan for a red/pink raised plaque found on a cat's eye?

The diagnostic plan involving testing for FeLV (Feline Leukemia Virus) and FIV (Feline Immunodeficiency Virus) alongside performing cytology is appropriate for evaluating a red or pink raised plaque on a cat's eye for several reasons.

First, the presence of a raised plaque suggests the possibility of an infectious or neoplastic process that could be influenced by viral infections, particularly in cats where FeLV and FIV are known to compromise the immune system. Testing for these viruses helps determine if there is an underlying systemic disease that may be affecting the cat's overall health and immune response, which is crucial when diagnosing skin lesions.

Additionally, cytology is a non-invasive procedure that allows for the collection of cells from the lesion to be evaluated microscopically. This can provide immediate information about the nature of the plaque, such as whether it is inflammatory, infectious, or neoplastic. The combination of these two diagnostic methods maximizes the chances of identifying the correct etiology of the lesion, guiding subsequent management and treatment decisions effectively.

This comprehensive approach is essential in veterinary practice, especially in cases that involve lesions near sensitive areas such as the eyes, where misdiagnoses can lead to serious consequences.
