Summary
Common feline skin tumors include basal cell, mast cell, squamous cell carcinoma, and fibrosarcoma. Older cats are more prone to these neoplasms, with Siamese cats showing a predilection for mast cell tumors.
Area of Science:
- Veterinary Dermatology
- Oncology
Background:
- Cutaneous neoplasms are a significant concern in feline health.
- Understanding the epidemiology of skin tumors in cats is crucial for diagnosis and treatment.
Purpose of the Study:
- To analyze the incidence and characteristics of cutaneous neoplasia in a feline population.
- To identify common tumor types, their age distribution, and common locations.
Main Methods:
- Retrospective analysis of biopsy and necropsy records from 3,564 cats over 41 months.
- Categorization of 18 types of skin tumors, focusing on the four most prevalent.
Main Results:
- 340 cases of cutaneous neoplasia were diagnosed.
- Basal cell tumors (26%), mast cell tumors (21%), squamous cell carcinoma (15%), and fibrosarcoma (15%) were the most common.
- Tumors predominantly affected cats over 10 years old, with mast cell tumors occurring in younger cats.
- Head was the most common site for basal cell tumors, mast cell tumors, and squamous cell carcinomas; legs for fibrosarcomas.
- Siamese cats showed a higher incidence of mast cell tumors and a lower incidence of squamous cell carcinomas.
Conclusions:
- Basal cell tumors, mast cell tumors, squamous cell carcinoma, and fibrosarcoma are the most frequent feline skin tumors.
- Age and breed (Siamese) are significant factors in the occurrence of specific feline skin tumors.
