An audit of pigmentation disorders due to infection seen at a private dermatology clinic in Western Australia

Pigmentation disorders have multiple causes ranging from endocrinopathies, medications, malignancies and infections. Infection related pigmentation changes of the skin may be the presenting complaint of several conditions including tuberculoid leprosy, Pityriasis versicolor, Tinea nigra and progressive macular hypomelanosis. Recognizing and considering an underlying infective process is important as effective treatment is achievable. For our audit, we aimed to determine the proportion of pigmentation disorders mediated by an infectious process among dermatology patients at a private dermatology clinic in Western Australia. In the initial part of the audit, records of a 3 month period was analysed.
Clinical correspondence letters of all patients who have been seen at our target dermatological clinic over a 3 month period from July to September 2016 were included in the audit. Only patients who were receiving an initial consultation were included in the study. Details regarding primary and secondary diagnoses were collected and analysed to determine the incidence of pigmentation related presentations and subsequent diagnoses.
We hope to assert, through our audit, the importance of considering an infective cause where relevant for pigmentation disorders seen in clinical practice.
