From mottled, a 17th-century adjective from mottle, meaning a blotched pattern, probably formed from motley.
What does mottled skin look like?
It looks like irregular patches, blotches, or a net-like pattern of color, often red, purple, blue, brown, or bluish-red depending on skin tone.
What causes mottled skin?
Common causes include cold exposure, reduced blood flow, medication reactions, autoimmune or vascular disease, infection, and circulation changes near the end of life.
Is mottled skin the same as a rash?
No. A rash usually involves inflammation, bumps, itching, or irritation, while mottled skin describes an uneven color pattern often linked to circulation.
Is mottled skin always serious?
No. It can be a temporary response to cold, but persistent, spreading, sudden, or unexplained mottling can signal a medical problem.
What is the medical term for mottled skin?
The common medical term is livedo reticularis, especially when the pattern is lace-like or net-like.
Can mottled skin go away?
Yes. Mottling caused by cold often fades with warming, while mottling from an underlying condition usually improves only when the cause is treated.
When should mottled skin be checked by a clinician?
It should be checked when it appears suddenly, persists, spreads, looks dark or lace-like, or comes with symptoms such as fever, confusion, pain, weakness, or trouble breathing.
