Objective To evaluate correlation and degree of agreement between dermatoscope and Wood’s lamp in diagnosis of melasma sub-types. Methods This is a cross-sectional study on 89 female with facial melasma from dermatologic clinic of Afzalipour Hospital, Kerman, Iran. Melasma lesions were classified to epidermal, dermal and mixed types with dermatoscope and Wood’s lamp. Correlation and degree of agreement between two diagnostic methods were evaluated by Kappa coefficient. Results Eighty nine females with melasma lesions were enrolled the study. Mean age of the participants was 37.57±6.84 (range 25-53) years old and most of the lesions were located on malar areas (51.3%). Based on Wood’s lamp examination, melasma lesions were classified to epidermal, dermal and mixed types in 88.8%, 1.1% and 10.1%, respectively. Based on dermatoscope evaluation, epidermal, dermal and mixed types were observed in 50.6%, 28.1% and 21.3% of the cases, respectively. Correlation between Wood’s lamp and dermatoscop was observed in 59.6% of the lesions (Kappa coefficient = 0.232, P. value=0.001). Conclusion Regarding to higher number of dark-skin phototypes in our geographical region and deeper visualization of dermatoscope to the dermis, dermatoscop is a better choice for determination of clinical subtypes of melasma.References
