Abstract

This study aimed to characterize mammary lesions in domestic cats through histopathological analysis, in order to diagnose the main types of mammary tumors and evaluate their distribution.

Sixty female cats, belonging to two breeds (Siamese and crossbred) and aged between 8 and 10 years, were examined between November 2022 and November 2024 in two provinces of Northeastern Algeria (Skikda and Sétif).

Clinical examination revealed mammary lesions in 30 cats (50%). Histopathological analysis identified malignant tumors in 18/60 (30%), benign tumors in 9/60 (15%) and atypical hyperplasias in 3/60 (5%). Malignant tumors were the most frequent, with several histological subtypes identified, including complex carcinoma, tubulopapillary carcinoma and squamous cell carcinoma. These findings emphasize the predominance of malignant forms in cats, the diagnostic value of histopathology and the importance of early detection and preventive measures such as early ovariectomy.
