Bizarre Parosteal Osteochondromatous Proliferation of Middle Phalanx: A Case Report

ABSTRACT

Although bizarre parosteal osteochondromatous proliferation does not frequently occur, this calcified, osteal, chondromatous tumor has relatively high recurrence rates and presents clinical, radiological, histological features that can be classified with other lesions. And it is a benign disease that until now, there were no death or metastasis reports because of this tumor. This proliferation is hard to distinguish between other benign tumors and non-neoplastic lesions if it is occurred in small bone of hand or foot. We experienced bizarre parosteal osteochondromatous proliferation of middle phalanx of the little finger, and report this case and the review of relevant literature.
