摘要

<h4 class="h4">Introductionh4>

Bone marrow necrosis is a very rare condition which is characterized by a necrosis of hematopoietic progenitors, adipocytes and reticulin network.<h4 class="h4">Case reporth4>

We report a 62-year-old woman admitted to an intensive care unit for an essential thrombocytemia associated with bone marrow necrosis complicated by septic shock and progressive multi-organ failure. To our knowledge, this is the second case reported in the literature. The clinical presentation of bone marrow necrosis includes non-specific symptoms such as fever, bone pain and sometimes a clinically significant medullar insufficiency syndrome. Biology can reveal cytopenias, elevated LDH and alkaline phosphatase serum levels. The diagnosis is confirmed by bone marrow trephine biopsy. Bone marrow necrosis is classified as extensive if more than 50%of the bone marrow biopsy show necrosis. Haematological malignancies (particularly leukaemia), and solid malignant tumours (particularly gastro-intestinal or lung cancers) represent up to 90%of aetiologies and must be actively researched. Also, sickle cell disease and catastrophic anti-phospholipid syndrome must also be investigated. Essential thrombocytemia remains an exceptional cause of bone marrow necrosis.<h4 class="h4">Conclusionh4>

Overall the prognosis of bone marrow necrosis is poor unless appropriate and intensive treatment, especially for sickle cell disease in which complete medullar regeneration has been observed.
