Abstract
We report a case of total hyperpigmentation of the skin, severe itching, muscle weakness and thrombocytosis. Laboratory investigation showed white blood cell (WBC) 8.2 × 106/L, Hb 125 g/L, platelets 1221 × 106/L and urinary lead after DMSA mobilization test 2684 mcg/g creatinine (normal <5). Chelation therapy with DMSA resulted in complete recovery of the hyperpigmentation, itching and thrombocytosis. Lead poisoning should be considered in the differential diagnosis of obscured thrombocytosis.
