Equine cutaneous non-neoplastic nodular and proliferative lesions in the Pacific Northwest.
Abstract: A retrospective study examined data on cutaneous nodular and proliferative lesions in horses, donkeys and mules submitted to the Veterinary Diagnostic Laboratory at Oregon State University in a 3.5-year period. One hundred and sixteen non-neoplastic nodular and proliferative lesions were identified, comprising 18% of all lesions studied and 6.4% of total equine pathology accessions. Exuberant granulation tissue, eosinophilic granuloma, fungal granuloma, cysts and habronaemiasis were most common, and constituted 91% of non-neoplastic lesions, 16% of all lesions studied, and 5.85% of total equine pathology accessions. Calcinosis circumscripta and cutaneous granulomas, including eosinophilic granuloma, fungal granuloma, and other granulomas, were most common in horses up to 10 years of age. Eosinophilic granuloma was more common in males than in females, and was diagnosed most often in autumn and winter. Fungal granuloma was common in this population and was most often diagnosed in the spring. Habronaemiasis was diagnosed in late summer and early autumn, and was most common in males. Results of this study indicate that equine non-neoplastic nodular and proliferative skin lesions are commonly submitted for histopathologic examination. Results also suggest that regional differences exist regarding incidence of cutaneous fungal granuloma and season of occurrence of eosinophilic granuloma in horses.

The research examines different types of skin lesions found in equines (horses, donkeys, and mules) in the Pacific Northwest, their prevalence, and any discernible patterns, including seasonal variations and gender differences.
Objective of the Study
- The main objective of this study was to examine and understand the different types of non-neoplastic nodular and proliferative skin lesions in equines and investigate their distribution based on the animal’s age, gender, and time of the year.
Methodology
- The researchers carried out a retrospective study, analyzing data from lesions submitted to the Veterinary Diagnostic Laboratory at Oregon State University over a period of 3.5 years.
- The lesions analyzed constituted a total of 18% of all lesions studied and 6.4% of total equine pathology accessions during this period.
Findings
- The analysis identified 116 non-neoplastic nodular and proliferative lesions including exuberant granulation tissue, eosinophilic granuloma, fungal granuloma, cysts and habronaemiasis, making up to 91% of non-neoplastic lesions considered, 16% of all lesions studied, and 5.85% of total equine pathology accessions.
- Calcinosis circumscripta and cutaneous granulomas were found more prevalent in horses aged up to 10 years.
- Eosinophilic granuloma occurred more frequently in males and was most often diagnosed during the autumn and winter seasons.
- Fungal granuloma was also common, with cases often diagnosed in the spring season.
- Habronaemiasis was diagnosed most frequently in late summer and early autumn, and was more common in males.
Conclusions
- The study contributes valuable data about non-neoplastic nodular and proliferative skin lesions in equines and their trends, indicating that such lesions are a common reason for histopathological examination in the field of equine health.
- The research also highlights that regional variations exist in terms of the incidence of certain skin conditions in equines, such as cutaneous fungal granuloma. Furthermore, the season of occurrence for some lesions (like eosinophilic granuloma) also varied.
