Abstract

One female newborn piglet showed prominent thickening of both forelimbs and died soon after birth. Histopathologically, thin and woven trabeculae of bone was extending out from the edge of cortical bone in the affected forelimbs, and diagnosed as congenital hyperostosis. The extent of radially proliferated trabeculae was most prominent in radioulna. Many round- to spindle-shaped cells were observed in periosteum, which were considered to be osteoblasts. Around the periosteum, the mesenchymal proliferation was extensive with abundant mucus, and cartilaginous metaplastic changes were observed mainly around the radioulna and humerus. Dilatation of vessels with fibrin deposition in vessel walls was often observed, which were considered to reflect the localized circulatory disturbance.
