Abstract

Introduction
An abscess is the most common swelling observed on the skin surface of the animal body with a collection of pus due to microbial invasion of the dermis and its supporting structures.
Case Description
In the present case, nine-years old male Zebu cattle were presented to the Veterinary Teaching Hospital (VTH) with a history of swelling on the cheek. Clinical findings of the mass revealed that there was well-circumscribed, firm, movable cold, and not painful superficial skin swelling on the body of the mandible and check. Culturing on blood agar and gram staining was conducted and then, Corynebacterium pseudotuberculosis was isolated from the sample. Following clinical and laboratory finding the case was diagnosed as caseous lymphadenitis and En bloc excision of the case was performed under local infiltration of anesthesia.
Conclusion
The suture was removed after 15-days post-intervention and the bull was successfully recovered without any other complications. Therefore, management of well-circumscribed, firm, and movable superficial skin abscess in cattle through en bloc excision along with antibacterial therapy and allowing the skin wound to heal by the first intention should be effective.
