Dermoscopic features of seborrheic keratosis and it’s prevalence in sulaimani city

Background: Seborrheic keratosis is one of the common benign epidermal tumors. Although most cases of seborrheic keratosis can be diagnosed clinically, knowing the dermoscopic features of it is of paramount importance to differentiate it from other clinically similar diseases (pigmented actinic keratosis, pigmented basal cell carcinom and malignant melanoma). Objectives To describe the morphological features of Seborrheic keratosis as seen by dermoscope and to investigates their prevalence. Patients and methods A cross sectional study that enrolled 60 patients with seborrheic keratosis using macrophotography and dermoscopy for the documentation of the cases. Results: A total of 8 morphological dermoscopic features were identified. The most common features were milia-like cyst (73.3 %) followed by comedo-like opening (31.7 %) and well demarcation (31.7 %). Conclusion: Seborrheic keratosis may present with a variety of dermoscopic features. Although the classical dermoscopic features (milia-like cyst and comedo-like opening) were the commonest features of seborrheic keratosis in this study, the presence of other features like fissure and ridges, fat finger, moth eaten border and hairpin vessels increase the diagnostic accuracy of seborrheic keratosis.
