Melanoma in private practice: do dermatologists make a difference?
Malignant melanoma is a major contributor to Australian morbidity and mortality. In this era of resource rationalisation, we seek to address the issue of whether routine full-skin examination by a dermatologist, rather than focussed examination of flagged lesions, will increase melanoma diagnosis. A retrospective chart review was undertaken between 1 July 2007 and 30 June 2008 in a private dermatology group practice in order to ascertain the number and characteristics of incidentally detected melanomas on routine skin examination. A total of 94 melanomas were detected during this 12-month period. Of these, 57 (60.6%) were incidentally detected by the dermatologist, 41 (71.9%) were in situ melanomas and 16 (28.1%) were invasive melanoma. Of the invasive lesions, 15 (94%) were 'thin' (less than 1.0 mm Breslow thickness). The majority of melanomas were found in men, and were distributed in areas of high cumulative sun exposure. Nine (9.6%) lesions were clinically misdiagnosed by the dermatologists and picked up on histopathology. This audit reaffirms the usefulness of routine full-skin examination by dermatologists in detecting de novo melanoma as part of the global strategy in reducing the burden of melanoma in Australia.
