Historical form of desmoplastic fibroma of the foot: a case report Volume 23, issue 2, Août 2007


Desmoplastic fibroma is a very rare primary bone tumour. Although considered a benign lesion, it can be very aggressive locally and has a high rate of local recurrence after incomplete surgical excision. Radiologically, the lesion shows no distinctive features, often resembling fibrous dysplasia or fibrosarcoma. Localisation in the foot or leg is uncommon. We report one case of the historical form in the foot and leg. Histological examination after surgical resection revealed that the tumor consisted of spindle cells with small, elongated nuclei on a background of numerous collagen fibres, infiltrating lamellar bone. There was no evidence of nuclear atypia, mitotic activity, or necrosis. We also discuss the histological differential diagnosis as well as clinical features and radiological and pathologic findings regarding this rare disease. Recognition of this entity is important to ensure proper surgical treatment.
