[Tarsonemus hominis in skin connective tissue].

Area of Science:

• Dermatology
• Parasitology
• Medical Entomology

Background:

• Skin biopsies are crucial for diagnosing various dermatological conditions.
• Naevus-like lentigines can sometimes present with unusual histological findings.
• The presence of ectoparasites in skin biopsies is uncommon but significant.

Observation:

• Histological examination of a skin biopsy from a 30-year-old male patient was performed due to a naevus-like lentigo.
• A mite was discovered within the upper dermis of the patient's skin sample.
• This represents a potentially novel observation in dermatopathology.

Findings:

• The identified mite was classified as a subspecies of Tarsonemus hominis Dahl.
• This is potentially the first reported case of Tarsonemus hominis subspecies found within human skin.
• The mite was located in the upper part of the corium.

Implications:

• This discovery expands the known host associations for Tarsonemus hominis subspecies.
• Further research is needed to understand the clinical significance and prevalence of this mite in human skin.
• The potential for mites to act as vectors for viral material warrants consideration in future investigations.
