title: A Pigmented Subcutaneous Nodule on the Scalp.
abstract: A 52-year-old man presented to his primary doctor with a slow-growing cystic lesion on his occipital scalp. His primary care doctor diagnosed the lesion as a pilar cyst and recommended observation because the lesion was asymptomatic at that time. The patient had no significant medical or surgical history. There was no family history of skin cancer or other malignancies.
