A 32 year old sports teacher presented via her puzzled general practitioner complaining of a gradual progression of shortness of breath when exerting herself at work. She also had an annoying cough and was uncharacteristically tired. Her only other complaint was of a sore red right eye that kept watering. On examination a small, non-tender lump was noted in the right supraclavicular fossa.
A chest radiograph shown here was taken.
