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 x 10(6)/L, Hb 125 g/L, platelets 1221 x 10(6)/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.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
