Excision of cutaneous tumors in the horse using histologic guidance.

The research is about adapting a successful human surgical technique for removing skin tumors into a similar process tailored for horses, with specific recommendations for changes to the method for equine application.

Study Overview

• The study experimented with a successful technique employed in human surgery for removing skin tumors and attempted to adapt it for usage on horses.
• The test subjects were seven horses with different types of skin cancers – squamous cell carcinoma and sarcoid.

Technique used

• In humans, a detailed inspection of the tumor base is undertaken using histological assessments drawn from horizontal sections of the tumor’s base.
• Accurate mapping is maintained between the wound surface and the excised tumor’s undersurface. This allows for accurate detection and removal of small remains of the tumor.

Suggested Modifications for Equine Usage

• Rather than using local anesthesia, it is suggested to place the equine patient under general anesthesia if the tumor is in a position difficult for standing surgery or if the patient is uncooperative.
• If frozen sections are not available, useful data can be gathered from tissue processed in buffered formalin.
• For this procedure, the optimal tumor size should be no larger than 3 x 2 cm.
