What is the subcutaneous tick in humans on the face called? - briefly
The condition is termed «subcutaneous tick» or more precisely an «embedded tick nodule». These lesions appear when a tick remains beneath the dermis, frequently on the facial region.
What is the subcutaneous tick in humans on the face called? - in detail
The subdermal tick that becomes lodged within the facial tissue of a human is referred to as an «intracutaneous tick». This term distinguishes the parasite from the more common superficial attachment where the mouthparts remain on the skin surface.
Clinical presentation typically includes a firm, painless nodule that may be mistaken for a cyst or granuloma. The nodule often appears weeks after the initial bite, as the tick remains alive beneath the epidermis. Overlying skin may show a small punctum or a faint discoloration corresponding to the tick’s mouthparts.
Diagnosis relies on visual inspection and, when necessary, imaging. High‑resolution ultrasound can reveal a hyperechoic structure within the dermis, confirming the presence of the organism. In doubtful cases, excisional biopsy provides definitive identification through histopathology.
Management consists of complete removal of the tick. Preferred techniques include:
- Local anesthesia followed by careful incision and extraction of the entire organism, ensuring no mouthparts remain.
- If the tick is deeply embedded, a small punch biopsy may be performed to excise the lesion en bloc.
- Post‑extraction wound care with antiseptic dressing and monitoring for secondary infection.
Potential complications arise from prolonged presence of the tick, such as local inflammation, secondary bacterial infection, or transmission of tick‑borne pathogens (e.g., Borrelia burgdorferi, Rickettsia spp.). Prompt removal reduces these risks.
Prevention strategies focus on regular skin checks after outdoor exposure, especially in wooded or grassy areas, and the use of repellents containing DEET or permethrin on clothing. Early detection of superficial attachment prevents progression to a subdermal location.
