Plain-English summary
A 23-year-old miniature horse (Falabella) was brought in for a recurring mass on the glans penis that had been noticed about a year prior. The veterinarian performed a partial phallectomy, which is a surgical removal of part of the penis, but unfortunately, the mass regrew, leading to urinary retention issues. Three months after the surgery, the horse was euthanized due to complications from the regrowth. The mass was diagnosed as equine sarcoid, linked to bovine papillomavirus type 1.

Abstract
A 23-year-old Falabella gelding kept in Tochigi, Japan, for more than 20 years presented with a recurrent mass of the glans penis that was first noticed about a year earlier. Partial phallectomy was performed with no adjunctive therapy for local regrowth of the mass. The horse was euthanized 3 months after surgery for urinary retention due to suspected regrowth. The resected mass affected the genital and urethral mucosa of the glans penis, and was diagnosed as equine sarcoid by histopathology and identification of bovine papillomavirus (BPV) DNA. Phylogenetic analysis of the BPV genome of the sarcoid showed high sequence homology to BPV type 1 (BPV-1) from Hokkaido, Japan, suggesting a geographical relationship for BPV-1 in Japan.
