Which skin symptom is associated with Steven Johnson's syndrome?

Stevens-Johnson syndrome (SJS) is characterized by a specific type of skin reaction that typically presents as localized morbilliform eruptions. These eruptions are typically reddish or purplish spots that can become elevated and may resemble measles or scarlet fever. The lesions can progress and lead to erosion of the skin and mucous membranes, particularly in severe cases.

Localized morbilliform eruptions are significant because they can signify the early stages of SJS and can help healthcare professionals identify and manage this serious condition promptly. In contrast, the other skin symptoms listed do not accurately reflect the typical presentation of SJS. For example, blisters covering the entire body are more indicative of toxic epidermal necrolysis, while dense pustules and diffuse rashes with severe itching point toward different dermatological conditions. Understanding the presentation of SJS is crucial for early detection and effective intervention.
