Histologic atypia in clinically benign nevi. A prospective study
Journal of the American Academy of Dermatology
|February 1, 1990
Summary
Histologic features typically associated with dysplastic nevi are common in benign acquired nevi. This finding suggests these features alone may not definitively diagnose dysplastic nevi.
Area of Science:
- Dermatopathology
- Histology
- Oncology
Background:
- Dysplastic nevi are often characterized by specific histologic features.
- Distinguishing dysplastic nevi from benign nevi is crucial for accurate diagnosis and patient management.
Purpose of the Study:
- To investigate the prevalence of histologic features of dysplastic nevi in benign acquired nevi.
- To assess the diagnostic utility of these features in common nevi.
Main Methods:
- Prospective study involving excision and histologic examination of 58 benign acquired nevi.
- Nevi selected met criteria for size (≤5 mm), symmetry, shape, pigmentation, margins, and absence of erythema.
Main Results:
- Histologic features of dysplastic nevi were present in 87.8% of benign nevi examined.
- Two or more such features were found in 69% of lesions, and all three features in 29.3%.
Conclusions:
- Histologic features commonly associated with dysplastic nevi are frequently observed in benign acquired nevi.
- These findings indicate that the presence of these histologic features alone is not sufficient for diagnosing dysplastic nevi.
