Abstract

To determine the immunohistochemical staining profile of intravenous leiomyomatosis (IVL), we analysed six IVLs and 12 ordi­nary leiomyomas (LM) for immunoreactivity with a panel of 11 antibodies. All IVLs and LMs reacted with antibodies to a-smooth muscle actin (a.sm), h caldesmon, vimentin and progesterone receptor (PR). Five of six IVLs and all LMs reacted with desmin. All IVLs were negative for CD-10. Only one LM exhibited focal CD-10 positivity. Three of six IVLs and nine of 12 LMs showed estrogen receptor expression. All IVLs and LMs showed immunnegativity with MIB-1 and inhibin. There were not any significant differences between immunoreactivity patterns of IVL and LM for asm, desmin, h caldesmon, CD-10, MIB-1 and PR. We conclude that, although they appear to be useful markers in differentiating IVL from ESS and LMS, a larger study also including ESS and LMS would be necessary to confirm their validity.
