A woman in her early 70s was referred to the dermatology department for evaluation of a solitary, asymptomatic lump on her scalp. She was born with the lesion but noticed some growth following a minor local trauma a couple of months prior to seeking medical evaluation. The patient denied local inflammation, purulent discharge, and systemic symptoms. Her medical history was unremarkable apart from an allegedly benign breast nodule resection in her teenage years. In addition, her father died of metastatic cutaneous melanoma at 83 years old.
