The official veterinary service sent skin samples to the SESC for diagnostic purposes.<\/p>\n<p>The skin samples were processed for histopathological study, through which multiple alterations were observed, mostly centered on the hair follicles. In these, diffuse atrophy is observed, with absence of hair and presence of disorganized keratin. Additionally, dilation of adnexal glands, dermal fibrosis, and perivascular lymphoplasmacytic inflammation are noted, findings interpreted as secondary to follicular atrophy. A diagnosis of alopecia due to <strong>congenital follicular dysplasia<\/strong> and <strong>secondary nonspecific dermatitis<\/strong> is made. It is also possible that the lack of hair made the animal more susceptible to solar radiation, contributing to dermal damage and inflammation.
