Perineal Subcutaneous Mineralized Tumor Caused by Perineal Hernia in a Dog

Abstract

A subcutaneous mineralized mass was found in the right perianal area of a twelve-year-old male miniature duchshund. The mass involving the circumference muscle, external sphincter of anus, obturator internus muscle, and coccygeus muscle, was surgically removed. Perineal hernia was identified after removing the mass. Histopathological examination revealed the presence of degenerated adipose and connective tissues and well-differentiated bone tissue in the mass, suggesting a diagnosis of paraprostatic cyst associated with perineal hernia.
