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.

기괴성 방골성 골연골성 증식증은 수부와 족부의 단관골의 표면에 발생하는 양성 종양이다. 치료는 일반적으로 변연부 절제술을 시행하지만 절제 후 국소적인 재발을 잘한다. 국내에서는 족부에 발생한 기괴성 방골성 골연골성 증식증에 대한 보고가 극히 드물다. 저자들은 44세 여자 환자에서 우측 제3족지의 근위지골에 발생한 기괴성 방골성 골연골성 증식증을 경험하고 이를 보고하고자 한다.

Nora et al. first reported a bizarre parostealosteochondromatous proliferation (BPOP) as a small size bone malformation mainly in the foot and hand in April 1983 that was called Nora's lesion or Nora's disease. Nora's disease is known for its low incidence and is characterized as a benign lesion, without a malignancy or metastasis with different histological, radiological, and clinical features from other common lesions. Several cases of Nora's disease on the hand, foot, and long bone have been reported in Korea. This paper reports a case of BPOP of the proximal phalanx of the great toe.

Bizarre parosteal osteochondromatous proliferation of bone (BPOP) was first described in 1983 by Nora et. al., who reported 35 cases of a bizarre proliferative lesion involving the small bones of the hands and less often the feet. These lesions simulate osteochondromas and conlain cartilage cap exhibiting atypical chondrocytes often undergoing ossification. Radiologically, they differ from osteochondromas. The lesion recurs in a significant number of cases after local excision, and the disturbing cytologic features may lead to a mistaken diagnosis of malignancy. The purpose of this report is to describe a case of bizarre parosleal osteochondromatous proliferation of the foot in a patient without traumatic history.
