Excision of a bizarre parosteal osteochondromatous proliferation (“Nora lesion”) in the hand: A case report
Author(s): Winston Wittesaele, Lukas Vanbecelaere and Marc Mombert
Abstract: Bizarre parosteal osteochondromatous proliferation is a benign osseous tumor mostly affecting the small bones of the hand and feet. Literature solely contains case series. Differential diagnosis has to be made with some other benign lesions but in particular with malignant tumors. Diagnosis is assumed upon a combination of suggestive clinical, radiological and morphological features, although histopathology is decisive in most cases. Awareness of this rare lesion is necessary for correct treatment and follow-up, because misjudging this pathology may lead to extensive resection and associated morbidity. Recurrence must be taken into account after surgical resection. This report describes a single case localized in the first webspace of the left hand without recurrence up until 24 months after surgical resection.
