Multiple Follicular Cysts in Four Alpacas (Vicugna pacos)
Follicular cysts are non-neoplastic skin lesions lined by follicular epithelium. The pathogenesis of these lesions is unclear. Multiple follicular cysts occur sporadically in dogs, horses and humans and are common in sheep. Here we report multiple follicular cysts in four aged alpacas (Vicugna pacos). Based on their histological features, they are most consistent with hybrid cysts. This is the first report of multiple follicular cysts in alpacas.
