Environmental dermatology: skin manifestations of injuries caused by invertebrate aquatic animals.

Haddad V - An Bras Dermatol (2013 Jul-Aug)

Bottom Line: Contact between humans and coastal areas has increased in recent decades, which has led to an increase in injuries from aquatic animals.The majority of these present dermatological manifestations, and some of them show typical lesions.The highest percentages of injuries that occur in marine environments are associated with invertebrates such as sea urchins, jellyfish and Portuguese men-of-war (echinoderms and cnidarians).

ABSTRACT
Contact between humans and coastal areas has increased in recent decades, which has led to an increase in injuries from aquatic animals. The majority of these present dermatological manifestations, and some of them show typical lesions. The highest percentages of injuries that occur in marine environments are associated with invertebrates such as sea urchins, jellyfish and Portuguese men-of-war (echinoderms and cnidarians). In this review, we discuss the clinical, therapeutic and preventive aspects of injuries caused by marine and freshwater invertebrates, focusing on first aid measures and diagnosis for dermatologists and professionals in coastal areas.

Mentions: Echinoderms are animals with rounded bodies and some species exhibit hollow spicules ofcalcium carbonate on the surface, capable of causing severe traumatic accidents (Figure 9). Some species of starfish (such as thespecies "crown-of-thorns") and sea urchins are venomous. In sea urchins, the venom hashypotensive and hemolytic neurotoxic and cardiotoxic effects, due to toxins present inthe pedicelaria, small tentacles that are located among the spikes.2,30Sea cucumbers (Holothuria) produce holothurin, a toxin that irritatesthe skin and mucous membranes.
