Thanks for your post hawk on Grover's disease. No, I have not been biopsied nor to a dermatologist but the information you provided certainly matches my symptoms, the colder weather and being a 74 y.o. white male fits the demographic. I will certainly discuss this condition with my oncologist during my next visit with him. My Bile Duct cancer did spread to become Liver cancer which also fits the Histopathology risk described in the research I was able to do thanks to the information you provided me. I will continue to post as I find out more. John
