Squamous Cell Carcinoma of the Vulva.

Squamous Cell Carcinoma of the Vulva.
Squamous cell carcinomas of the vulva in the cow are locally invasive. The prognosis is poor unless detected early and radically excised. They usually start as squamous metaplasia in the nonpigmented portion of the labia of older cows. These lesions become very contaminated and are constantly irritated by friction from the tail.
