It is characterized by systemic calcification of soft tissues, that can progress to death when severe cardiovascular lesions are present. We describe an episode of EC in sheep after exposure to hay contaminated with S. glaucophyllum. In a sheep flock of 17 male, 8-10 months old, 2 died spontaneously. Grossly, hydrotorax, lung edema, and aorta artery and myocardial multifocal-coalescing mineralization was observed. Microscopically, systemic mineralization of blood vessels was present in aorta, kidney and heart characterized by basophilic granular deposits in tunica intima and/or tunica media. Myocardial multifocal-coalescing areas of myofiber loss and regeneration, characterized by macrophage and satellite cell infiltration intermingled with fine granular basophilic deposits (mineralization) was evident. Von Kossa stain confirmed mineralization as calcium deposits. Furthermore, sheep outbreaks are sparsely reported, contributing to knowledge of the disease in other species, in addition to cattle, and in an unusual presentation as forage reserves. During hay production, inspection of possible toxic plants, such as S. glaucophyllum, must be carried out. La calcinosis enzoótica (CE), por ingestión de la planta tóxica Solanum glaucophyllum, es una enfermedad crónica bien conocida en Argentina que afecta al ganado bovino en sistemas de pastoreo extensivo. Se caracteriza por una calcificación sistémica de los tejidos blandos, que puede progresar hasta la muerte cuando hay lesiones cardiovasculares graves. Describimos un episodio de CE en ovejas después de la exposición a rollo contaminado con S. glaucophyllum. En un rebaño de 17 ovinos machos, de 8 a 10 meses de edad, 2 murieron de forma espontánea. Macroscópicamente, se observó hidrotórax, edema pulmonar, y mineralización multifocal-coalescente de la arteria aorta y en miocardio. Microscópicamente, había mineralización sistémica de los vasos sanguíneos en aorta, riñón y corazón, caracterizada por depósitos granulares basófilos en la túnica íntima y/o la túnica media. En miocardio se evidenciaron áreas multifocales coalescentes de pérdida de cardiomiocitos con regeneración, caracterizadas por infiltración de macrófagos y células satélite entremezcladas con depósitos basófilos granulares finos (mineralización). La tinción de Von Kossa evidenció los depósitos de calcio en los tejidos afectados. Los episodios de intoxicación por consumo de S. glaucophyllum en ovejas son escasamente reportados, lo que contribuye al conocimiento de la enfermedad en otras especies además del bovino, y en una presentación inusual como reserva de forraje. Durante la producción de rollo se debe realizar una inspección de posibles plantas tóxicas, como S. glaucophyllum.
