“…Infrequent cases of mammary neoplasms have been reported in cattle (POVEY & OSBORNE, 1969;MINA et al, 1994), mares (HIRAYAMA et al, 2003;BRITO et al, 2008), water buffalo (MANDAL & IYER, 1969), and goats (SINGH & IYER, 1972); whereas, hyperplastic changes have been observed in cattle (HONG et al, 1994) and water buffalo (SANT'ANA et al, 2014). Mammary epithelial hyperplasia is classified into three distinct types: lobular (arising from the intralobular ducts), ductal (arising from the extralobular ducts), and adenosis (CASSALI et al, 2011).…”
