Dermatological aspects of ticks in Australia: An update.

Ticks are ectoparasites that cause dermatologic reactions directly by their bites and indirectly as vectors of bacterial, protozoal and viral diseases. Consequences vary from minor local reactions to significant systemic sequelae and are therefore of clinical relevance to dermatologists. In this article, Australian ticks of medical importance are reviewed through the lens of dermatology.

Late-onset eccrine syringofibroadenoma of the feet in a patient with hypohidrotic ectodermal dysplasia.

A 56-year-old woman with hypohidrotic ectodermal dysplasia presented with a 10-year history of persisting wart-like skin lesions on her feet. Biopsy revealed changes of eccrine syringofibroadenoma. These lesions are rare, with only nine case reports describing an association with ectodermal dysplasia of hidrotic type (Clouston and Schopf's syndrome).
