An uncommon presentation of non-small-cell lung cancer with acrometastases to the great toe and index finger

Abstract

A 71-year-old white woman was referred to the emergency department by her primary care physician for necrosis and swelling of the left great toe for work-up of possible osteomyelitis (Figure 1). Before she presented to her physician, she had been complaining of severe pain, swelling, and erythema of the left great toe that had lasted for 1-2 months. Infection was initially suspected. She completed 2 courses of oral antibiotics with no improvement. She was also complaining of similar symptoms on the left index finger and attributed her symptoms to an injury a month earlier (Figure 2). The pain was so severe that she was not able to bear weight on her left foot. An outpatient X-ray of her left great toe raised her physician's concerns that it might be osteomyelitis so she was referred to the emergency department.
