What does a tick look like in a wound? - briefly

A tick embedded in a wound appears as a small, oval, dark‑brown or gray body that may be partially swollen and attached firmly to the skin, often with its mouthparts visible as a tiny protrusion. The surrounding tissue can show redness or a slight puncture mark where the parasite penetrated.

What does a tick look like in a wound? - in detail

A tick attached to skin tissue presents as a small, rounded body ranging from 2 mm in larval stages to 10 mm or larger in adult females. The dorsal surface is typically a smooth, leathery shield called the scutum, which may be brown, reddish‑brown, or black depending on species and engorgement level. When feeding, the abdomen expands dramatically, becoming balloon‑like and often translucent, revealing a pale, creamy coloration that contrasts with the darker scutum.

The head region, or capitulum, protrudes forward and includes the chelicerae and hypostome. The hypostome is a barbed structure that anchors the parasite within the wound, appearing as a tiny, dark, serrated projection. Surrounding the capitulum, the palps are small, segmented appendages used for sensory perception; they are usually lighter in color and may be partially hidden by the engorged body.

The attachment site often shows a small puncture or oval opening at the point where the hypostome penetrates the skin. Surrounding tissue may display erythema or a faint, localized swelling. In cases of prolonged attachment, a clear, serous fluid may be observed seeping from the wound, and the surrounding skin can develop a thin, dark scab as the host’s immune response reacts to the foreign body.

Key visual characteristics include:

  • Rounded, smooth dorsal shield (scutum) of brown to black hue
  • Enlarged, translucent abdomen indicating blood intake
  • Prominent, dark, barbed hypostome extending from the front
  • Small puncture or oval opening at the attachment site
  • Possible peripheral erythema or mild swelling

Recognition of these features enables accurate identification of a tick within a wound and informs appropriate removal and medical management.
