A 72-year-old woman presented with a painful scalp mass that had initially been diagnosed as a scalp hematoma after a fall that had occurred 5 months earlier. The mass had rapidly enlarged and started to bleed. The patient then developed a left parotid mass and multiple new satellite lesions adjacent to the scalp mass. Physical examination revealed a 9 × 10-cm nodular ulcerated mass located on the posterior aspect of the scalp with 3 additional 2-cm satellite lesions (Figure 1). Multiple ipsilateral enlarged cervical lymph nodes were also observed.
