I was diagnosed with lichen planopilaris about 2 years ago confirmed with biopsy.After trials of clobetasol and olux-E there was little improvement.I was then placed on plaquenil with improvement to my lichen planopilaris.I developed a severe rash with hives and redness from my neck to my knees,front and back after 9 months of plaquenil. I was taken off plaquenil and used steroid cream with improvement,but the rash did return and I was placed on prednisone. After this failed,my dermatologist did a biopsy resulting in Grover's disease. This is an extremely itchy condition.Even with atarax,halobetasol cream,and calcipotriene cream, the itchiness continues and interrupts my sleep.Zyrtec helps during the day but does not last as long as it did initially. My derm wants me to go back on plaquenil because my planopilaris is worsening and I now have lumps on my head, some of which are painful. My question is two-fold: Is there a relationship between the two diseases? Any causes or cures?
