Chapter 20 Lower limb pain
Case 20.1
A 40-year-old man presents with a number of lesions on his foot which have been present for nearly a year. He states that the dark coloured lesions were originally skin coloured, with the same type of surface, but have changed over the last few weeks. They tend to be painful when he walks. The lesions are shown in Figure 20.1.
Case 20.2
A 28-year-old woman presents with a 1-week history of malaise, fever and arthralgia. She thought she had the flu, but 3 days ago a rash appeared on her legs. During this time, it has become redder, firmer and more tender. Her joint pain is predominantly involving her ankles and knees. Three weeks earlier she had an upper respiratory tract infection with a sore throat and a mild fever, but has otherwise been quite healthy. She takes no medications, does not smoke and is a social drinker. There has been no history of trauma. The rash is shown in Figure 20.2.
