[Pruritus of dark skin in hookworm infection].

Using the example of a young man from Senegal we would like to point out that in cases of pruritus without an underlying skin disease an intestinal parasitosis might be the cause of the pruritus should the patient come from the tropics. However, it is important to use concentration methods when examining stool specimens so as to be able to diagnose the parasitosis. The causal connection between a pruritus and an intestinal parasitosis needs to be confirmed by a successful treatment.
