CASE REPORT
A 37-year-old man was wading in the shallow ocean
water of a Southern California beach when he felt a
sudden sharp pain in his right foot. Upon exiting the
water, he noticed a small pointed object embedded in the
sole of his foot (Figures 1 and 2). The skin around the
wound appeared mottled (Figure 1). He began to expe-
rience excruciating, throbbing pain in the foot to the
point of near-syncope. On the advice of the beach life-
guard he immediately returned home and submerged his
foot in a bathtub of hot water. This greatly relieved his
pain, but upon removing his foot from the water the pain
returned. After several hours of soaking his foot he was
able to tolerate the pain out of the hot water with oral
analgesics. By the next day he was nearly pain free. He
developed a tender swelling in the right groin over the
next week, but recovered uneventfully, never seeking
professional medical care.
DISCUSSION
The coastal waters of the United States are home to 22
species of stingray (1). These are cartilaginous fish of the
same class as sharks (Elasmobranchii) (1,2). The Urolo-
phidae (round stingrays) and Dasyatidae (whiprays) pre-
dominate the temperate waters of the West and South-
eastern U.S. coasts, respectively (1,3). These wide, flat
fish propel themselves through the water with their wing-
like pectoral fins. Stingrays also possess one or more
sharp spines at the base of a whip-like tail. These spines
