A Unusual Case of Slowly Enlarging Hyperpigmented Lesion Over Abdomen- A Case Report.

A non malignant neoplasm arising from epithelium is seborrheic keratosis, which can manifest as one or several tumors. It's an skin tumor that's commonly seen in the elderly. Benign tumors, malignant tumors and premalignant lesions can clinically present as seborrheic keratosis (SK).[1] Here, a patient presented with a large longstanding hyperpigmented raised lesion over the abdomen, suspected to be Seborrheic keratosis. Most Seborrheic Keratosis show distinct , asymptomatic clinical features but some studies have reported malignant changes including sudden growth of lesion, ulcerations, color changes,[2] All things considered, SK might resemble other lesions grossly and even a chance to turn malignant. Thus, it is essential to carry out proper histological examinations and then administer appropriate treatments, especially to individuals who have a strong suspicion of malignancy.[3] A biopsy is most accurate and diagnostic in distinguishing Seborrheic keratosis from benign premalignant lesions and other malignant lesions like squamous cell carcinoma,Malignant melanoma etc [4]
