What does an embedded tick look? - briefly
An embedded tick presents as a tiny, dark, rounded lump with its mouthparts sunk beneath the skin. The surrounding area may be slightly reddened or irritated, and the tick’s body can appear swollen.
What does an embedded tick look? - in detail
An embedded tick presents as a small, oval or round body attached firmly to the skin. The dorsal surface is typically brown, tan, or reddish, with a smooth, glossy texture. As feeding progresses, the tick swells, becoming noticeably larger—up to the size of a pea or larger—while the color deepens to a darker brown or black.
Key visual characteristics include:
- Head and mouthparts: The capitulum (head) protrudes forward, forming a short, pointed projection that may be visible as a tiny black tip. This structure is the feeding apparatus and remains anchored in the skin.
- Body segmentation: The tick’s body consists of two main regions. The anterior capitulum is distinct from the larger posterior idiosoma, which expands during engorgement.
- Attachment site: The surrounding skin often shows a small, circular area of erythema or a faint halo. In some cases, a clear or serous fluid may accumulate around the attachment point.
- Movement: Once attached, the tick’s legs are hidden beneath the skin, and the organism appears immobile. Any movement is limited to subtle adjustments of the mouthparts.
When examining a suspected attachment, follow these steps:
- Visual inspection: Look for the characteristic pointed head and the enlarged, rounded body.
- Palpation: Gently press around the perimeter; the tick should feel firmly anchored, with no easy detachment.
- Skin reaction assessment: Note any redness, swelling, or a small ulcerative crater that may indicate a prolonged bite.
- Size comparison: Compare the tick’s dimensions to a known reference (e.g., a grain of rice) to gauge the feeding stage.
Recognizing these features enables accurate identification and timely removal, reducing the risk of pathogen transmission.
