Objective: To determine whether excision was an acceptable treatment for dermal melanomatosis in horses.
Design: Retrospective study.
Animals: 11 horses with dermal melanomatosis involving the perineal, perianal, or perirectal region or ventral surface of the tail in which treatment consisted of tumor excision.
Procedure: Medical records were reviewed. Follow-up information was obtained from owners through telephone interviews.
Results: 9 of the 11 horses were alive at the time of follow-up interviews. None of the horses had regrowth at the surgery site where the primary tumor was removed. There were no confirmed clinical signs of internal metastasis.
Conclusions And Clinical Relevance: Results suggest that excision of dermal melanomatosis in horses may be a reasonable treatment option.

Equine Melanocytic Tumors: A Narrative Review.
Animals (Basel)
January 2023
Veterinary Sciencies Department, University of Trás-os-Montes e Alto Douro, 5000-801 Vila Real, Portugal.
Adult grey horses have a high incidence of melanocytic tumors. This article narratively reviews the role of some genetic features related to melanoma formation in horses, such as STX17 mutation, ASIP or MITF alterations, and the link between the graying process and the development of these tumors. A clear system of clinical and pathological classification of melanocytic tumors in naevus, dermal melanoma, dermal melanomatosis and anaplastic malignant melanoma is provided.

Article Synopsis
- Melanoma is highly prevalent in gray horses, with rates exceeding 50%, and genetic predisposition has been linked to a specific duplication in the STX17 gene.
- A study conducted a genome-wide association analysis on 141 Lipizzan horses, identifying the DPF3 gene on chromosome 24 as a potential factor in melanoma development.
- Further research involving 1210 horses from multiple breeds suggests that a specific genotype of the DPF3 gene may help suppress melanoma, highlighting its importance for gray horses at risk of developing this condition.

[Malignant melanoma of the pelvis as a possible cause of pelvic limb lameness in two gray mares].
Tijdschr Diergeneeskd

Faculteit der Diergeneeskunde, Universiteit Utrecht, Utrecht.
Two grey mares, a 12-year-old Arabian and a 13-year-old Lippizaner cross, were referred for chronic pelvic limb lameness and abduction of the limb during the non supporting phase of the stride. The clinical examination revealed melanomas under the tail and on the perineum, and oedema of the proximal lame limb. A mass in the pelvic area was detected on rectal palpation.
