Abstract
- Bizarre parosteal osteochondromatous proliferation (BPOP) is an rare benign tumor which involve mostly tubular bones of feet and hand. BPOP has clinical, radiographic, and histologic similarities with osteochondroma.Radiologically, BPOP has not central continuity with underlying osseous medulla. Histologically, the lesion has marked proliferative activity, and enlarged, bizzare, and binucleated chondrocytes.Despite the high risk of recurrence, treatment of choice is surgical resection. This report presents two cases of BPOP of the big toe with reviews of clinical, radiographic, and histological characteristics.
