Case Description- An eight-year-old, light brown and crossbred stallion in a horse-racing club had two gray skin masses on his left thigh and thoracic inlet with a slow growth since two years ago. The masses were 5×7 cm in size, irregular shaped with some convex parts. Surface bleeding had been reported occasionally. CBC and WBC were within normal values. General clinical examination of the animal revealed no problem.
Treatment and Outcome- Under general anesthesia (premedication, induction and maintenance by xylazine and ketamine) two neoplastic masses were excised completely. The lesions were restricted to skin with no subcutaneous tissue involvement. Histopathologic results confirmed cutaneous fibroma based on numerous fibroblasts and collagen fibers. There were no recurrence or any other complications in post-operative monitoring for six months.
Clinical Relevance-  Treatment of cutaneous fibroma is complete by surgical excision in ablating the tumor masses and preventing re-growth.
