Differential Diagnosis
- Single most likely diagnosis
- Burrowing mite (e.g., Demodex or Cheyletiella): These mites can cause skin lesions and may appear as a crown-shaped structure on the skin, with the head breaking off as the mite burrows deeper.
- Other Likely diagnoses
- Lice (e.g., Pediculus humanus or Felis catus): While the description doesn't perfectly match lice, some species can cause skin lesions and may be mistaken for other parasites.
- Mites (e.g., Sarcoptes or Trombicula): Other types of mites can cause skin lesions and may be considered in the differential diagnosis.
- Insect bites (e.g., mosquito or midges): Certain insect bites can cause skin lesions that may resemble a crown shape.
- Do Not Miss
- Leishmaniasis: A parasitic disease caused by Leishmania species, which can cause skin lesions that may be mistaken for other conditions.
- Cutaneous larva migrans: A condition caused by the migration of larvae through the skin, which can cause skin lesions and may be mistaken for other parasites.
- Rare diagnoses
- Myiasis: A condition caused by the infestation of fly larvae, which can cause skin lesions and may be considered in the differential diagnosis.
- Tungiasis: A condition caused by the infestation of Tunga penetrans (chigoe flea), which can cause skin lesions and may be considered in the differential diagnosis.
