Bizarre parosteal osteochondromatous proliferative lesion of the hallux

Abstract

Foot tumors are a rare occurrence, which can make diagnosis and management difficult. Certain benign tumors can be locally
aggressive, with a rapid progression resembling a malignancy. We present a case of bizarre parosteal chondromatous proliferative
(BPOP) lesion, also known as Nora lesion, arising from the sesamoid. This is a benign lesion with overlapping clinical and radiological
features of a malignant neoplasm. Highlighting classic BPOP characteristics is crucial in avoiding potentially incorrect management
and resulting morbidity. Levels of evidence IV; Therapeutic studies; Case Report
