Abstract: Objective To study the clinicopathological features and differential diagnosis of bizarre parosteal osteochondromatous proliferation (BPOP). Methods The clinicopathological features of 3 patients with BPOP were analyzed , and related literature was reviewed. Results 3 patients included 2 males and 1 female with an average age 40 years old (24-53 years old). The lesions in three patients were located in the left side of the distal radius, the left side of the little finger inside and the right side of ulna coracoid, respectively. Histologically, characterized by unusual mineralized cartilaginous matrix (`blue bone'), the lesion was composed of a heterogeneous mixture of bone, cartilage and fibrous tissue. Conclusion BPOP is a rare benign surface osteocartilaginous lesion, and its diagnosis and differential diagnosis mainly depend on radiographic and histopathologic features.
