Objective—To determine outcome of horses in
which cutaneous masses were removed with a carbon
Procedure—Medical records of horses with 1 or
more cutaneous masses treated with a carbon dioxide
laser were examined. Follow-up information was
obtained through telephone interviews with owners
and referring veterinarians.
Results—Cutaneous masses were classified as sarcoids
(15 horses), neoplastic masses other than sarcoids
(squamous cell carcinoma ; fibroma ; and
melanoma ), and nonneoplastic masses (6).
Minimum follow-up time was 6 months. Five sarcoids
and 2 squamous cell carcinomas recurred. Seven
(21%) horses had complications associated with
dehiscence of wounds that had been closed primarily
or failure of wound healing because of recurrence of
the mass. Twenty-six (81%) owners were satisfied
with the cosmetic appearance following surgery.
Conclusion and Clinical Relevance—Results suggest
that a carbon dioxide laser may be effective for
treatment of cutaneous masses in horses. (J Am
