Summary
Focal epithelial hyperplasia (FEH) lesions in two sisters initially mimicked sexual abuse. Despite various treatments, the oral mucosa lesions resolved spontaneously, highlighting a unique clinical course.
Area of Science:
- Oral Pathology
- Dermatology
- Pediatric Dentistry
Background:
- Focal epithelial hyperplasia (FEH), also known as Heck's disease, is a benign oral mucosal condition.
- It is primarily associated with specific human papillomavirus (HPV) types, notably HPV 13 and 32.
- Accurate diagnosis is crucial, as FEH can be mistaken for other conditions, including signs of abuse.
Observation:
- This case study details two sisters of Mexican ancestry presenting with FEH.
- The oral lesions in the older sister were initially misdiagnosed as indicative of sexual abuse.
- Histopathological examination confirmed the diagnosis of FEH.
Findings:
- Human papillomavirus (HPV) types 6, 11, 13, and 32 were not detected in the patient's tissue via in situ hybridization.
- The FEH lesions demonstrated persistence and recurrence despite the application of destructive treatment modalities.
- Complete spontaneous resolution of the oral lesions was observed over time.
Implications:
- This case underscores the importance of considering FEH in the differential diagnosis of oral lesions, especially in pediatric patients.
- The lack of detectable HPV in the affected tissue challenges typical etiological associations.
- The spontaneous resolution suggests that conservative management may be appropriate for certain FEH cases, even after initial persistence.
