Which of the following is NOT a characteristic of dermatitis?

Dermatitis is primarily characterized by inflammation of the skin, which manifests through notable symptoms and signs. Intense itching is a common feature, as it is a reaction of the skin to irritation and inflammation. Erythema, or redness of the skin, occurs due to increased blood flow to the affected area as part of the inflammatory response. Various lesions can also develop in dermatitis, including rashes, blisters, or scales, depending on the specific type of dermatitis and its severity.

Pearlescent nodules, on the other hand, are more typical of conditions like basal cell carcinoma or other types of skin tumors rather than dermatitis. These nodules have a smooth, glossy appearance and do not fit the common presentation of dermatitis, which is focused on inflammation and irritation rather than tumor-like growths. Thus, this characteristic is not aligned with the typical manifestations of dermatitis.
