Final answer:
The symptoms described by the 52-year-old woman are indicative of lichen planus, an autoimmune condition. On physical examination, white, lacy patches on the mucous membranes, as well as erosions on the vulva and possibly bald patches on the scalp, are likely findings.
Step-by-step explanation:
The 52-year-old woman's symptoms of vulvar irritation, burning, dyspareunia (painful intercourse), contact bleeding, oral lesions, and bald patches are suggestive of an autoimmune disease. Based on the presentation, the likely diagnosis is lichen planus, which can affect the skin, mucous membranes, and genitals, leading to a variety of symptoms as mentioned above. On physical examination (PE), one may find white, lacy patches on the vulva or in the mouth, as well as possible erosions or ulcerations. In addition, areas of alopecia (bald patches) on the scalp may be noted.
