The patient, a 36-yr-old Polynesian man, presented with a 3-month history of swelling of his extremities with clubbing of the fingers and toes and polyarthritis affecting his hands, feet and knees. Plain radiographs revealed extensive periosteal reaction along the shafts of the metacarpals (arrow in A). Axial proton density fat saturated sequence on MRI shows periosteal new bone (short arrow in B) involving the shafts of the metacarpals giving a halo appearance. There is also associated periosteal oedema showing high signal (long arrow). The patient was eventually diagnosed with a high-grade undifferentiated pleomorphic sarcoma of his left ventricle (C, D). The hematoxylin and eosin (H&E) section taken from the resected tumour (C) shows pleomorphic spindle cell proliferation, bizarre nuclei and atypical mitoses.
Vascular endothelial growth factor (VEGF), a cytokine normally inactivated in the lungs, has been implicated in the pathogenesis of hypertrophic osteoarthropathy [1].
