The skin reaction caused by the penetration of larval schistosomes in humans has been designated in different ways depending on the geographical area. However, ‘cercarial dermatitis’, a term coined by Vogel in 1930 [1], is widely used for this worldwide emergent disease. Although currently highlighted due to non-human parasites, especially avian schistosomes [2], this name is also used for species of Schistosoma that cause human schistosomiasis in some tropical developing countries. The adequacy of ‘cercarial dermatitis’ to define the condition was firstly questioned by Cort in 1950 [3] and the nomenclatural discussion recently restarted by Morley in 2015 [4] is an extremely relevant issue.
