Most dogs had either an exogenous or an endogenous source of corticosteroids, with the exception of five dogs with renal insufficiency. In the majority of cases, mineralization was found throughout the entire dermis. The average age of onset of calcinosis cutis for dogs with endogenous hyperglucocorticism was older than that of dogs with iatrogenic hyperglucocorticism. Using infrared spectrometry, apatite crystals were found to be the source of mineral.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions and clinical importance<\/jats:title><jats:p>There was no observable difference in the histopathological pattern of calcinosis cutis from dogs with endogenous hyperglucocorticism versus iatrogenic hyperglucocorticism. While glucocorticoid therapy appears to predispose dogs to developing calcinosis cutis, it remains unclear whether there is a specific dose or combination of factors that initiates the mineral deposition. Furthermore, the mineral deposition in dogs with calcinosis cutis was found to be apatite.<\/jats:p><\/jats:sec>","DOI":"10.1111\/vde.12026","type":"journal-article","created":{"date-parts":[[2013,4,8]],"date-time":"2013-04-08T16:15:45Z","timestamp":1365437745000},"page":"355","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Calcinosis cutis in dogs: histopathological and clinical analysis of 46 cases"],"prefix":"10.1111","volume":"24","author":[{"given":"Katherine A.","family":"Doerr","sequence":"first","affiliation":[{"name":"William R.
