Plain-English summary
This report discusses a 4-year-old Spanish purebred stallion that developed multiple cysts on its body over two years. The cysts, which were firm and ranged in size from half an inch to about three inches, appeared in various places but did not cause itching. Five of these nodules were surgically removed and examined, revealing they were simple epidermal cysts, which are filled with a substance called keratin. These cysts were not present at birth, but their slow growth and early detection suggest they were likely there from birth. This type of condition has not been previously documented in young horses or specifically in Spanish purebred horses.
Abstract
This case report describes a case of multiple follicular cysts in a 4-year-old Spanish purebred stallion. The lesions ranged in size from 0.5 to 3 cm in diameter, and were firm, well circumscribed and nonpruritic. They developed over a 2-year period with a generalized distribution affecting all body regions. Five nodules were removed and histopathologically corresponded to simple epidermal cysts (infundibular and isthmus-catagen) with squamous epithelium and a keratin filled cavity. Lesions were not evident at birth but their number, early age of detection, slow growth and lack of previous trauma suggested that they were congenital. To the authors' knowledge, this condition has not previously been reported either in young horses or in Spanish purebred horses.
