[Benign skin tumours]

Benign skin tumours are commonly seen by general practitioners. They are important to differentiate from skin malignancies. Most benign skin lesions are diagnosed based on the history and clinical features. However, if the clinical diagnosis is uncertain, a skin biopsy, e.g. excisional or punch for histopathological examination is necessary to rule out malignancy. Seborrheic keratoses are the most common benign skin tumours with an increasing incidence with age. Other common benign skin lesions include melanocytic naevi, acrochordons and dermatofibromas, which may resemble malignant neoplasms.
