- a 25 year old sixth year medical student, 3 weeks into her last rotation in the internal medicine department, complained of an annoying scratching sensation at the back of her neck. She was otherwise healthy and was not taking any medication. Physical examination revealed a wet and edematous rash with sharply demarcated, weeping, eczematous plaques distributed over the neck [Figure, arrows]. A thorough history-taking revealed that the student was wearing her stethoscope around her neck during the day-to-day work in the ward. She removed the stethoscope from her neck, keeping it in the right pocket of her white coat during her work on the ward. Within one week after the offending agent was removed, the eruption was resolved without the need for other treatment.
