In conclusion, the results of the present study show that 1 immunoreactivity for ER and PR can be demonstrated immunohistochemically, by means of the microwave method, in the LAM cells of patients who have not received hormonal treatment; 2 the immunoreactive LAM cells have an epithelioid morphology and are also reactive for HMB 45 antibody, and 3 the reactivity for ER and PR is markedly diminished or abolished by hormonal treatment, most likely because of downregulation of the receptors <a href=https://stromectol.ink/>ivermectin for goats</a> Lancet 388, 2997 3005 2016
