Acute mercury poisoning (acrodynia) mimicking pheochromocytoma in an adolescent

J Pediatr. 1993 Feb;122(2):252-3. doi: 10.1016/s0022-3476(06)80125-3.


A 14-year-old boy was seen because of irritability, insomnia, lethargy, and profuse sweating, together with hypertension (blood pressure: 160/120 mm Hg), tachycardia, and a diffuse erythematous rash with desquamation of the palms and soles. Initial biochemical investigation suggested a diagnosis of pheochromocytoma, but subsequently a history of exposure to mercury vapor was obtained. This case emphasizes the clinical and biochemical similarities between mercury poisoning (acrodynia) and pheochromocytoma.
