Final answer:
Given the symptoms of a 59-year-old woman with facial pain and swelling, Systemic Lupus Erythematosus is a likely diagnosis, considering its characteristic symptoms including a butterfly rash and widespread inflammation.
Step-by-step explanation:
A 59-year-old woman presenting with pain and swelling of the face may be suffering from several possible conditions.
However, given the age and symptoms, Systemic Lupus Erythematosus (SLE) is a likely diagnosis. SLE is an autoimmune disorder that can cause a characteristic butterfly rash on the face, as well as symptoms like fever, photosensitivity, and joint arthritis, according to Figure 20.6.6. The autoimmune nature of SLE means that the body incorrectly targets its own tissues, leading to widespread inflammation, which could explain the facial swelling.
