A 52-year-old woman attends clinic for investigation of abdominal pain and constipation. On examination you note blue lines on the gum margin. She mentions that her legs have become weak in the past few days. What is the most likely diagnosis? A. Acute intermittent porphyria B. Lead poisoning C. Constipation D. Guillan Barre syndrome E. Rectal carcinoma
This is not a good question. What's the patients pmhx, hpi, living conditions, etc.. we need more info. The blue line on the gums is Burton's line, which is indicative of chronic lead poisoning, and constipation is also a symptom. more symptoms point toward lead poisoning but we need a more detailed medical history and exam to make a clinical dx.
