A 5 years old, male donkey was presented to the clinic with a six – months swelling
at the postero-medial aspect of the leg just below the stifle joint. The swelling was hard in consistancy except at the apex. The skin was completely movable over it. A sharp object was palpated at the base of the swelling. Exploratory puncture revealed nothing. Radio¬graphic examination indicates presence of soft tissue mass medial to the tibial bone and contains a variable shadow of hard objects. Histopathological examination revealed presence of osteophyte at the medial aspect of the leg in a donkey.
