Correlation between dermatoscopic findings and histopathological subtypes of seborrheic keratosis
Abstract
Aim. Seborrheic keratosis is a benign epidermal tumor, mostly seen in elderly. It has six histopatohological subtypes, including acantotic, hyperkeratotik, irritated, reticular, clonal type
and melanoacantoma. Dermatoscopy (epiluminisence microscopy) is an in vivo, noninvasive technique showing invisible morhological properties of pigmented skin lesions and tumors. The
aim of this study was to determine whether there is a correlation between dermatoscopic findings and histopathological subtypes of seborrheic keratosis.
Method. 80 lesions from 53 patients were included the study. Dermatoscopic findings of the lesions were defined. Incisional biopsy of 77 lesions and excisional bopsy of three lesions were taken and histopathological subtypes were determined.
Results. There was not a significant correlation between histopathological subtypes and some dermatoscopic findins, including comedo-like openings, milia-like cysts, fissures, polimorpheus vessels, dots/globules and blue-white structures (p>0.05). Sausage fingers were more frequent in hyperkeratotic irritated type of seborrheic keratosis (p<0.05). Milia-cloud was more frequent in irritated type, and pseudostreaks and pseudoreticular pattern was more frequent in reticular type of seborrheic keratosis (p<0.05).
Conclusion. Dermatoscopy as a diagnostic tool may be used for the identification of some histopathological subtypes of seborrheic keratosis.
