A 16-year-old girl presented with a tan, painless indurated nodule on her right shoulder. The lesion had developed several years before presentation and was reported to have increased in size over time. The patient's medical history was unremarkable.
Physical examination revealed a well-circumscribed, 2-cm, tan, indurated nodule on the posterior aspect of the right shoulder (Figure 1). Manipulation of the nodule elicited no discomfort. There was no supraclavicular or axillary lymphadenopathy. A punch biopsy specimen was obtained (Figure 2 and Figure 3).
