How does the skin look if a tick has entered? - briefly

The attachment site usually presents as a small, raised, firm papule that is pink or reddish, often with a dark central dot where the tick’s mouthparts are embedded. Surrounding skin may display a faint halo of erythema.

How does the skin look if a tick has entered? - in detail

When a tick attaches, the skin surface shows a small, raised bump roughly the size of a pinhead to a pea, depending on the tick’s developmental stage. The central point often appears as a dark, pinpoint opening where the tick’s mouthparts have pierced the epidermis. Surrounding this focal point, a halo of redness may be present; the erythema can be faint or pronounced, sometimes forming a circular pattern that expands as the host’s inflammatory response intensifies.

The surrounding tissue may feel slightly warm to the touch, and mild swelling can develop within a few hours. In cases where the tick’s legs are visible, a tiny, brownish or grayish oval shape can be seen protruding from the puncture site. If the tick remains attached for several days, the lesion may become more pronounced, with increased edema, possible bruising, and occasional itching or tenderness.

Typical visual indicators include:

  • Small, dome‑shaped elevation at the attachment site.
  • Dark central punctum indicating the feeding apparatus.
  • Variable erythema radiating from the core.
  • Visible tick body partially embedded in the skin.
  • Localized swelling or warmth.

If the tick is removed improperly, the mouthparts may stay embedded, leaving a tiny, linear scar or a persistent tiny opening that can become a focus for secondary infection. Signs of infection comprise expanding redness, pus formation, increasing pain, or fever, all of which require prompt medical evaluation.
