Swamp stone powder is also known as carrion stone. It may be sold as a material for removing the smell of underarm odor and sweaty feet. After local use of carrion stone for underarms, lead oxide compound presented in this material, is absorbed to the body due to its high absorption through the skin. In this study, middle-aged woman who has been diagnosed with lead poisoning following consumption of swamp stone is introduced.
A 44-year-old woman was admitted to emergency unit of clinical toxicology department because of abdominal pain that began 40 days before admission. Vital signs were PR = 84 / min, SBP / DBP = 131/80 mmHg, RR = 18 / min and SPO2 = 96% on admission. The patient was completely alert and able to answer questions. She had a feeling of drowsiness and vague pain in the abdomen Since two months before admission. Physical examination, generalized abdominal tenderness was detected and several air fluid levels were seen in PA and AP supine abdominal XRs. The abdominal ultrasonography that was performed one month before admission reported grade one fatty liver; results of spiral abdominal and pelvic CT scan showed several hyper dense particles in ascending colon and cecum two days before admission. This finding was suspicious to lead poisoning. Blood Lead level (approximately 113 μg /dL) was high. Chelating therapy by British anti-Lewisite (BAL or dimercaprol) and EDTA was performed during a 5 days course in hospital, and after the end of treatment, abdominal pain was improved.
