76-Year-Old Woman With A Bluish-Purple Lump In Her Left Upper Medial Leg

A woman, aged 76 years, presented with a bluish-purple lump in her mid- to upper medial left thigh. It started initially as a flat rash, and over a 2-month period, it turned into a mass measuring 2.5 cm by 3.1 cm. Work-up, including a PET-CT scan, showed the soft tissue mass on the inner thigh to have a Standardized Uptake Value of 4; there were no other sites of disease. A biopsy of the lesion was performed.
