Focal epithelial hyperplasia, a rare oral condition caused by human papilloma virus (HPV), presents as benign growths. This case highlights HPV serotype 13 in a young Ecuadorian patient, expanding geographic and demographic understanding.

Area of Science:

  • Oral pathology
  • Viral infections
  • Dermatology

Background:

  • Focal epithelial hyperplasia (FEH) is a rare oral mucosal condition linked to human papilloma virus (HPV).
  • FEH typically manifests as benign epithelial growths, predominantly on the lower lip.
  • The condition shows a racial predilection, being more common in Native Americans and Eskimos, and is associated with HPV serotypes 13 and 32.

Observation:

  • A case study of a 17-year-old female patient from Ecuador is presented.
  • The patient exhibited multiple papular lesions on both lips.
  • Clinical and histological examinations confirmed the diagnosis of focal epithelial hyperplasia.

Findings:

  • Polymerase chain reaction (PCR) analysis was performed on the lesions.
  • HPV serotype 13 was detected in the patient's oral lesions.

Related Experiment Videos

  • This finding supports the association of HPV 13 with FEH in a diverse geographic and ethnic population.

    • Implications:

    • This case expands the known geographic distribution of focal epithelial hyperplasia.
    • It underscores the role of HPV serotype 13 in the etiology of FEH across different populations.
    • Highlights the importance of considering HPV in the differential diagnosis of oral papular lesions.
