Influence of chronic arsenic poisoning on bone marrow morphology. A case report.

Arsenic is widely used for the production of insecticides, paints, ceramics and for the preparation of textiles, leather and furs. Nevertheless hematologists are almost unaware of the influence of arsenic on bone marrow morphology. In the case described here we have found slight megaloblastic hemopoiesis, typical karyorrhexis in erythropoietic accompanied by basophilic stippling and impairment of mitoses in megakaryocytes and granulopoietic cells.
