How to recognize a subcutaneous tick on the face? - in detail
Identifying a subdermal tick on facial tissue requires careful visual inspection and tactile assessment. The parasite typically embeds its mouthparts beneath the epidermis, leaving only a small, often translucent, dome or a pinpoint puncture visible on the skin surface.
Key visual indicators include:
- A raised, rounded elevation that does not move freely when the surrounding skin is lifted.
- A darkened or reddish spot at the center of the bump, corresponding to the tick’s abdomen.
- Absence of a clear, hard shell; the exoskeleton remains hidden beneath the skin.
Tactile clues are equally important. Gently palpating the area with a clean fingertip or sterile gauze should reveal a firm, immobile nodule. The surrounding tissue may feel slightly inflamed or tender, but the lesion itself does not compress easily.
Additional diagnostic steps:
- Illuminate the area with a bright, angled light to accentuate subtle color differences.
- Use a magnifying lens (10×–20×) to examine the perimeter for tiny legs or a faint outline of the tick’s body.
- Compare the lesion with reference images of subcutaneous ticks to confirm morphology.
If uncertainty persists, obtain a high‑resolution photograph and consult a dermatologist or infectious disease specialist. Prompt identification is crucial because the tick may transmit pathogens such as Borrelia spp. or Rickettsia spp.
Removal procedure:
- Apply a topical anesthetic (e.g., lidocaine 2 %) to reduce discomfort.
- Use fine‑point sterile forceps to grasp the tick’s mouthparts as close to the skin as possible.
- Pull upward with steady, even pressure, avoiding twisting or crushing the body.
- Disinfect the extraction site with an antiseptic solution (e.g., chlorhexidine).
After extraction, monitor the area for signs of infection—redness, swelling, or pus formation—and seek medical evaluation if any of these develop. Recording the date of attachment and removal assists clinicians in assessing the risk of vector‑borne disease.
Regular skin checks after outdoor exposure, especially in wooded or grassy environments, reduce the likelihood of missed subdermal infestations. Early detection and proper removal minimize complications and prevent disease transmission.
