Lung multiple fibroma in Bactrian camels

Multiple fibroma in lungs of 2 of the dessected 5 Bactrian camels from Alashanyouqi, lnner Mongolia, were found, which occured in both the surface and interior of the lungs showing hard nodules varying in size and number with the round appearance showing greywhite colour. By the histological observation, the tumour tissues were composed of a number of collagenous and fibroblasts. There were less cells at the centre of the tumours than these at the edge of the tumours. It was seen that the young cells of the tumours surrounded the capillaries and formed many new growing central focus.
