Giant Seborrheic keratosis- A Rare Entity

Abstract

Background: Seborrheic Keratosis (SK) is most common benign epidermal tumor with distinctive “stuck on” appearance. It appears on the sun-exposed sites with equal sex distribution in middle- and old-aged individuals. Head, neck and trunk are the common sites. They often range in size from a few millimetres to a few centimetres.They are usually slow growing, however, clinical changes such as sudden increase in size, color change and ulceration may indicate malignant change.Case Presentation:The purpose of this review is to report a case of an unusually large, seborrheic keratosis on the face, highlighting its clinical and histopathological features.The manifestations pointed towards malignancy and the patient underwent biopsy and complete excision with a favorable outcome. Investigation: Even though they are clinically diagnosed, SK mimickers are well known, with melanoma being the most worrisome. Dermoscopy is used to help with diagnosis when uncertainty arises, as various benign and malignant conditions must be considered in the differential diagnosis due to their morphological diversity.Management: Treatment options include surgical therapy,laser therapy, electrocautery, cryosurgery, shave excisions and laser-assisted removal. Conclusion:Giant SK, an atypical SK is uncommon and can manifest in an unusual way, and histopathological analysis is warranted to look for concomitant malignancy.
