Equine tongue tumours: A multicentre retrospective study
Background
Tumours of the oral cavity in horses are rare, and because they are not easily visible, their diagnosis is often delayed. Different types of equine tongue tumours have been described, but information about clinical signs, treatments and outcomes is very limited.
Objectives
To identify horses with a confirmed antemortem diagnosis of a tongue tumour and to document their clinical presentation, treatment and outcome.
Study design
Retrospective multicentre study.
Methods
Medical records (1997–2024) from eight specialty or referral practices were reviewed. Horses met inclusion criteria if an antemortem diagnosis of a tongue tumour was made and confirmed by cytology or histopathology.
Results
Thirteen horses met the inclusion criteria. Presenting complaints included one or more of the following: tongue mass (4) or wound (2), difficulty eating (6), external facial swelling (2) and abnormal respiratory noise (2). Tumours were identified as squamous cell carcinoma (SCC) (5), melanoma (2), mast cell tumour (2), anaplastic carcinoma (1), poorly differentiated carcinoma (1), B-cell lymphoma (1) and neuroendocrine tumour (1). Seven of 13 horses (54%) underwent surgical treatment. Five of the seven (71%) had no recurrence for ≥1 year, and two were euthanised earlier for reasons other than tumour regrowth. One mast cell tumour responded to conservative treatment. All horses with SCC were euthanised following palliative or no treatment.
Main limitations
The main limitations are the small sample size, a result of the rarity of the condition and the diversity of performed diagnostics and treatments, a consequence of the multicentre study design.
Conclusion
Horses with tongue tumours frequently present for evaluation of a tongue laceration or mass and biopsy or cytology is required for definitive diagnosis. While the prognosis for lingual SCC was uniformly grave, surgical excision for other types of tongue tumours carried a good long-term prognosis in this study.
期刊介绍:
Equine Veterinary Education (EVE) is the official journal of post-graduate education of both the British Equine Veterinary Association (BEVA) and the American Association of Equine Practitioners (AAEP).
Equine Veterinary Education is a monthly, peer-reviewed, subscription-based journal, integrating clinical research papers, review articles and case reports from international sources, covering all aspects of medicine and surgery relating to equids. These papers facilitate the dissemination and implementation of new ideas and techniques relating to clinical veterinary practice, with the ultimate aim of promoting best practice. New developments are placed in perspective, encompassing new concepts and peer commentary. The target audience is veterinarians primarily engaged in the practise of equine medicine and surgery. The educational value of a submitted article is one of the most important criteria that are assessed when deciding whether to accept it for publication. Articles do not necessarily need to contain original or novel information but we welcome submission of this material. The educational value of an article may relate to articles published with it (e.g. a Case Report may not have direct educational value but an associated Clinical Commentary or Review Article published alongside it will enhance the educational value).
