Abstract
|
|
|
The case was described of a 31 year old female who developed fusiform swelling of the right third finger at the site of puncture by sea urchin spine. We observed a radiopaque linear material suggesting a remnant spine which the size was 2.4 mm in
sonography and mammography. We confirmed that it exhibits a urchin spine and distinct caseous necrosis with central calcification.
Sea urchins(Echinoidea) are ubiquitous marine creatures that resemble pincushions and are covered by calcareous skeletons surrounded by numerous movable calcium carbonate spines. The sharp spines are brittle and easily detach when touched by the
victim.
Contact with sea urchin spines produces intense pain, some localized erythema and edema. Inflammation develops in response to retained fragments. Granulomas 1-5 mm in diameter develop rarely 2-12 months after envenomation.
In treatment, hot water immersion and thorough wound cleansing are advisable. Analgesics may be necessary after hot water immersion. Attempts to remove these spines should be performed with good lighting sources, preferably with radiological
direction.
Chronic granulomas usually require complete excision. Acetone has been suggested for rapid resolution of pain. No antidotes are available.
