Unexpected parasitosis.

Neotrombicula autumnalis is an arthropod living in the soil and parasitizes animals only in its larval stage. Depending on climatic conditions, one to five life cycles can take place in a single year. Human infestation is probably underestimated and can be easily missed due to non-pathognomonic cutaneous manifestations in absence of systemic signs. We describe a case of human trombiculiasis and discuss the diagnostic and therapeutic management of this ‘synanthropic’ dermatosis.
