A patient presents with the following clinical picture: initially there were individual pruritic, discrete, shiny, reddish-violet, flat-topped papules one-half to 5mm in diameter. These papules coalesced into larger lesions as they became more numerous. There are pathognomonic gray lines on the flat surface of the papules. The lesions are symmetrical in distribution and are located on the flexor surfaces of the wrist, forearms, ankles, abdomen, and sacrum. There are a number of linear eruptions following scratches on the body where the skin has been damaged. This condition is most likely
a. Intertrigo

avery easily with short exposure to sunlight
A. Acne rosacea
A common pruritic skin lesion frequently associated with asthma and hay fever
C. Atopic dermatitis
A symptom complex with systemic manifestations and skin lesions. The skin
lesions are papular at first and later become vesicles and bulla
