Case ReportExtensive Dystrophic Pulmonary Calcification in a Welsh Pony Mare
Introduction
Dystrophic pulmonary calcification is a rare clinical syndrome associated with varying underlying disorders in humans, dogs, and horses. This case report describes a case of extensive generalized dystrophic pulmonary calcification involving both cranioventral lung lobes to an extent not reported before. No signs of neoplasia, previous respiratory disease, or metabolic disease were present.

Case Presentation
A 12-year-old Welsh pony mare was presented for a history of lethargy and increased respiratory effort. The pony was used as a show hunter up until the time of presentation. For 6 months before presentation, the pony began tiring easily when being ridden and intermittent increased abdominal effort during breathing was observed. No coughing or other signs were observed. Appetite and fecal output were normal. The referring veterinarian reported no abnormalities on repeated physical examination.
Discussion
Ectopic calcification, which is defined as inappropriate formation of mineral crystals in soft tissue, which normally do not mineralize, occurs as squeal to varying underlying disorders and is divided broadly into metastatic and dystrophic calcification. Deposition of calcium in dead or dying tissue is termed dystrophic calcification, whereas metastatic calcification is defined as mineralization as a sequel to an underlying abnormality in regulatory mechanisms that prevent and activate
