A – Z of Skin

Information for Skin, Hair and Nail Conditions


The A to Z of Skin information has been developed to help you understand more about common skin conditions and problems, and how these may be treated.

Both common and medical names have been included to help your search, as well as the names of medications and treatments. There are also a number of cosmetic topics which explain the latest treatments for cosmetic concerns related to the skin. Many College dermatologists have contributed to the information on this site.

The process has been overseen by a committee of dermatologists to ensure that the final versions are both accurate and user friendly. Particular thanks go to Dr Pam Brown, Dr Peter Berger, Dr Davin Lim, Dr Michelle Rodrigues, Dr Yin Vun, Conjoint Associate Prof Orli Wargon and Dr Eleni Yiasemides (Chair). The A to Z information is currently under development. Please check back on a regular basis for updates and the addition of new topics.

  • Sand-worm eruption

    Sand-worm eruption also known as cutaneous larva migrans, is an itchy localised skin infestation caused by the penetration and migration of animal hookworm larvae through the skin.

  • Sarcoidosis

    Sarcoidosis most commonly affects the lungs but can also affect the skin and other organs. It is characterised by the formation of “granulomas” in affected areas. These are organised collections of histiocytes (a special type of inflammatory cell).

  • Scabby mouth

    Scabby mouth also known as Orf is an infection caused by the parapox virus which primarily infects sheep and goats. The condition is most commonly seen in animal handlers, butchers and farm workers. Anyone can become infected by touching the affected animals or by contact with infected pastures. Orf occurs worldwide.

  • Scabies

    Scabies is a condition that occurs as a result of infestation with a tiny mite (parasite) called Sarcoptes scabei var hominis.

  • Scar treatments

    Scars can result from injury to the skin through disease and trauma. Common examples include burn scars, acne scars and surgical scars. Individual scars can be further classified as raised (hypertrophic or keloid), depressed or atrophic. Inflammation to the skin can also result in skin colour changes including red scars and scars that are darker than the surrounding skin known as post-inflammatory hyperpigmentation.
