Atopic dermatitis
type of inflammation of the skin
Atopic dermatitis (AD), also known as atopic eczema, is chronic type of inflammation of the skin. Atopic dermatitis is also often called simply eczema, but "eczema" is also used to refer to dermatitis, the larger group of skin conditions. Atopic dermatitis results in itchy, red, swollen, and cracked skin. Clear fluid may come from the affected areas, which can thicken over time. The thickening phenomenon is known as lichenification.
Atopic dermatitis affects about 20% of people at some point in their lives. It is more common in younger children. Females are affected slightly more often than males. Millions of people have outgrown the condition.
While the condition may occur at any age, it typically begins in childhood, with varying severity over the years.
Begin with the source’s own compact description: “Atopic dermatitis” is type of inflammation of the skin. The dossier treats that line as a proposition to test through Atopic, dermatitis and type, not as a finished interpretation.
Why this record matters
The phrase “type of inflammation of the skin” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 15, 2026. The linked authority identifier is Q268667. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
