We present a clinical, histologic, and photographic record of a not uncommon dermatologic entity caused by the bite of a small marine crustacean.
These organisms of the order Isopoda, sub-order Cymothoidea, frequent the shoal waters of temperate and tropical seas.4
Cymothoids usually feed upon higher marine animals but will indiscriminately attack man.
