Background:
Dermoscopy increases the diagnostic accuracy of clinical visual inspection by 5% to 30%. This has led to a reduction of
unnecessary excision of benign skin lesions and the earlier diagnosis of malignant skin lesions.
Objectives:
To compare the concordance agreement of the clinical versus histopathologic diagnosis to the concordance agreement of the
dermoscopic versus histopathologic diagnosis of pigmented lesions.
Research Design:
This is a prospective, cross-sectional study of the clinical, dermoscopic and histopathological features of pigmented skin
lesions on patients seen at the Out-Patient Departments of Quirino Memorial Medical Center and Ospital ng Makati from March 2013 to
June 2014.
Methods:
Sixty-eight subjects fulfilled the criteria and were all included in the final analysis. Classification and definitive diagnosis of the
lesion as benign or malignant were determined thru clinical, dermoscopic and histopathologic features by one dermatopathologist. Kappa
and concordance analyses were performed to determine the statistical and concordance agreement among the results of the three
diagnostic procedures, respectively.
Results:
The statistical agreement between clinical versus histopathologic classification as benign or malignant was good (kappa=0.872),
while the statistical agreement was high (kappa=0.872) between dermoscopic versus histopathologic classification. Concordance
agreement between clinical versus histopathologic diagnosis showed fair agreement (concordance coefficient=0.2397) as compared to a
high agreement (concordance coefficient=0.98) in dermoscopic versus histopathologic diagnosis.
Conclusion
The use of dermoscopy in pigmented lesions aids the dermatologist in giving an accurate diagnosis without invasive
procedures. Knowledge of the dermoscopic features will help in the early clinical detection and management of benign and malignant
pigmented skin lesions.
