Polydactyly hypopigmented cat with squamous cell carcinoma
Polydactyly, hypopigmentation, and squamous cell carcinoma are common in cats. However, a cat exhibiting all of these conditions has not yet been reported. This study presents the case of a 14- year-old male Mexican cat, hypopigmented, with supernumerary fingers, two preaxial and one on each posterior limb, admitted to the clinic with a lesion in the left periocular region.
A general physical examination, blood, and urine chemistry, as well as a biopsy and genomic instability assessment with an analysis of the red blood cells (RBC) micronucleated erythrocytes (RBC-MNE) in the peripheral blood was performed.
The biopsy was positive for squamous cell carcinoma, and the red blood cell-micronucleated erythrocyte count was high compared to that previously described in other domestic cats or wild cats. Thus, the genomic instability of the red blood cell-micronucleated erythrocyte could be used as an indicator to identify clinical conditions of felines, particularly those with one of the characteristics exhibited by this Mexican cat.
