Question: Cold sore like blisters on chest arm and forehead

 jobabyjojo - Tue Jun 29, 2010 4:26 pm

Hi ive got a rash which initially the pharmacist and others were saying was chicken pox even though ive had that before. they are basically just like cold sores except they are not on my mouth i have 4 across my chest one developing on my wrist and nose and 3 on my forehead. they are extremely itchy, starting out looking like lil red spots with puss inside but if you itch developing into a blister, exactly like cold sores. ive mostly been putting calamine lotion on them and holding ice on them to curb the itching. theyve been developing over the last 5 days and ive been to my gp and he didnt know what it was just mentioned urticaria and gave me betnovate cream and prescribed antihistamines for the itching. ive been looking online and cant find anything described like this... please if you can help identify this, i don't want this spreading even more over my body.

here are some pictures

User avatar Hello,The clinical picture and the picture sent makes one think of Dermatitis Herpetiformis a condition caused due to circulating immune complexes. The patient's skin would develop very itchy,vesicular lesions arranged in a group and urticaria like rashes.Early picture may be very difficult to diagnose and may resemble pox.Scalp,face,chest,back are the areas of predilection and later are symmetrical as the condition advances.
This condition is associated in some with gluten sesitization.
Though I can not say with certainity just from photographs, you may need a complete blood analysis,and biopsy to get a definitive diagnosis.
Other than DH we have to also think of common bullous impetigo(More common in children),other viral skin infections,and contact dermatitis.
Best wishes.
