This report describes the occurrence of enzootic calcinosis in buffaloes in the municipality of Pocone, Mato Grosso, due to the consumption of Solanum glaucophyllum (Sg) [=Solanum malacoxylon]. The cases were observed in the years 2007 and 2009. In a herd of 40 buffaloes, five showed weight loss, arched back, stiff gait, sometimes difficulty to raise and walk, and leaning on the carpus. Three buffaloes recovered partially and two were euthanized in extremis. The main necropsy findings were calcification of soft tissues, especially of large and medium arteries. The presence of S. glaucophyllum in the pasture, clinical signs, in addition to the sonographic and pathologic calcification involving tendons and other tissues, are consistent with Solanum glaucophyllum poisoning.
