Cyclosporine treatment of perianal gland adenoma concurrent with benign prostatic hyperplasia in a dog.

Abstract

A 13-year-old, intact male, mixed-breed dog was evaluated for multiple intradermal nodules around the anus. The nodules were diagnosed as perianal gland adenoma based on histopathologic examination. After therapy with cyclosporin A for 5 wk, the perianal masses were moderately shrunken. The dog's condition has remained stable over 6 mo.
