A 34-Year-Old Woman Comes to the Office with Several Months

A 34-year-old woman comes to the office with several months of vision problems, difficulty chewing, and trouble speaking.  The symptoms fluctuate, but the patient has noticed that they are worse after a long day.  She works as a telemarketer and has been putting in increasingly long hours to meet her quotas.  Regarding her symptoms, she says, "It's probably just exhaustion; an ice pack to my face seems to help."  During physical examination, the patient is asked to keep her eyes focused on a spot on the ceiling, and after 2 minutes, her vision becomes blurry.  The remainder of the examination is normal.  Further evaluation shows that the patient's symptoms are reversible on administration of an acetylcholinesterase inhibitor.  The pathogenesis of this patient's disease is most similar to which of the following conditions?

A) Atopic dermatitis
B) Contact dermatitis
C) Goodpasture syndrome
D) Hypersensitivity pneumonitis
