Quizplus · Accepted Answer

The vesicles on a reddened base in a symmetrical pattern on the lower neck and upper back, along with the patient's description of discomfort prior to the rash, are characteristic of dermatitis herpetiformis (DH). DH is an autoimmune disease that presents with a rash of small, itchy blisters and typically affects the back of the neck, elbows, knees, and buttocks. It is associated with celiac disease and can be diagnosed by skin biopsy and blood tests for celiac antibodies. Herpes zoster typically presents with a painful, unilateral rash in a dermatomal distribution, while dishydrosis and contact dermatitis usually affect the palms and soles.
