Question: biopsy reveals pityriasis lichenoides
|luvumason - Sat Nov 22, 2008 10:17 pm||
Hi, I am a 23 yr old female that over the past month developed odd bumps on the tops of my legs. I went to see my doctor who said, it's probably just viral but, let me know if it's still there in a week. Of course, it got worse just over that short period of time. My doctor sent me to see a dermatologist who decided to do a biopsy. The biopsy revealed that I had pityriasis lichenoides. My doctor has tried me on every cream, and oral medication you could think of but, these bumps have now spread to the bottoms of my legs, stomache, and all over my arms. I hear that this is a rare disease and I am having problems finding out much information about it. Can you give me any? What caused this to happen to me???

Pityriasis lichenoides is a fairly rare disease, but not terribly dangerous, just very annoying for the most part. It may be caused by the Epstein-Barr virus (as with mono), but there are a number of other suspects as well. It can take a more debilitating course, with fever and ill-feeling, but also often is confined to a chronic, milder course that comes and goes.
There are a large number of potential therapies for it, as you've already discovered, but this is largely a trial-and-error process, and sometimes it takes a while to find which ones are effective for a given patient. Oral tetracycline and erythromycin have been used most often, but hydrocortisone cream and various other combinations of tetracycline, azithromycin, erythromycin, sulfonamides, dapsone, chloroquine, streptomycin, isoniazid, penicillin, methotrexate (MTX), etretinate, and pentoxifylline are often tried, with varying results. It's a pretty annoying process, but generally some combination of these will work. It just takes a lot of patience while finding the right combo for you.
I hope this is helpful to you. Please follow up with us here as needed, and keep us updated as to your progress. Best of luck to you.
