Abstract

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.
