A still image of a transient rash captured by a mobile phone.

ABSTRACT

The diagnosis of adult onset Still's disease (AOSD) can be difficult as the differential diagnosis is broad, it is based on clinical criteria and the signs, for example rash, can be transient. Clinical photography has an obvious role, and with modern technology, is now in the hands of physicians. We report a case of AOSD where an image of a transient rash taken with a camera phone allowed the diagnosis to be established. Further, we discuss the controversies around hospital bans on mobile phones (due to potential incompatibility with medical devices) and the reality of their widespread use. We conclude that, providing safeguards of consent and data storage are in place, the camera phone is a useful tool in rheumatology practice.
