A 73-year-old man presents with an 18-month history of a pigmented lesion on his left cheek. Patient History:  He had not paid much attention to it and had assumed it to be a ‘sun spot’. However, his daughter is concerned that it has been enlarging slowly and appears to be getting darker in color. She had taken her father to the GP who had then referred him to the dermatology out-patient department. The patient is a retired roofer and keen gardener. He takes aspirin and an antihypertensive medication.
