The authors report their experience with 6 cases of bizarre parosteal osteochondromatous proliferation (BPOP) observed in 4 patients in its typical site (distal ends of the limbs), and in 2 patients where it was instead atypically localized in the humerus and femur. The histories of the patients revealed that 50% reported previous trauma in the site of lesion. Five patients were submitted to surgical exeresis, while the remaining patient refused to undergo any type of treatment because he was asymptomatic. At a mean follow-up of 36 months 1 patient presented with recurrence (20%). BPOP is a rare pseudotumorous lesion with typical radiographic and histopathologic findings similar to to those of other benign and malignant tumor forms. A review of the small amount of literature in existence is used to analyze the elements that may lead to accurate differential diagnosis.
作者报告了他们对4例在典型部位（四肢远端）观察到的怪异骨旁骨软骨瘤样增生（BPOP）以及2例在肱骨和股骨非典型部位观察到的BPOP患者的6例病例的经验。患者病史显示，50%报告病变部位曾有过创伤。5例患者接受了手术切除，而其余1例患者因无症状拒绝接受任何治疗。平均随访36个月时，1例患者出现复发（20%）。BPOP是一种罕见的假瘤性病变，具有典型的影像学和组织病理学表现，与其他良性和恶性肿瘤形式相似。本文通过回顾现有的少量文献来分析可能有助于准确鉴别诊断的因素。
