Figure 1. Patient No. 9. (a) B-mode ultrasound shows a well-demarcated solitary homogeneous hypoechoic splenic tumour. (b) Colour-Doppler ultrasound shows a tumour with marked diffuse intratumoral flow signals. (c) The lesion is composed of small inconspicuous round lumina surrounded by broad strands of collagen fibre-rich connective tissue (haematoxylin and eosin x 200). (d) Immunohistochemistry (x 200) demonstrates a peculiar network of small capillaries lined by CD34 positive endothelia (sclerosing capillary haemangioma).
