Background: Of all GP consultations, 15% are for dermatological conditions-4% of these require referral to a dermatologist.In this study we assess the value of polaroid photography in helping a dermatologist manage patients referred from GPs. Our objective was to determine whether a polaroid photograph(s), with a clinical history, enables a final diagnosis & management plan to be made without the patient having to see the dermatologist face to face.

Of the 27 photo-diagnosis patients who needed to be seen, 20 attended their out-patient appointment and in 19 (95%) of these the face-to-face diagnosis was identical to the photo-diagnosis.In one case the diagnosis was changed from eczema to psoriasis.
