This paper reports on the clinicopathological features of four patients with solitary fibrous tumours arising from the extremities and presents a review of the relevant literature. The patients consisted of three women and one man, with a mean age of 47.8 years. Standard pre-operative work-up data were examined, including: history, clinical examination, plain radiography, computed tomography scans of the lesion and chest, magnetic resonance imaging, angiography, technetium-99m bone scan, thallium-201 scintigraphy and routine laboratory tests. Immunohistochemical staining was performed for CD34, Bcl-2 protein, vimentin, S-100 protein, desmin and smooth muscle actin, and pathological material was reviewed for the presence of histologically malignant components. Immunohistochemically, all of the tumours were diffusely positive for CD34. Clinical and radiological findings of solitary fibrous tumours affecting the extremities are reminiscent of those of aggressive or malignant soft tissue tumours. Pathological and immunohistochemical studies are important in making the correct diagnosis.
