What causes may-hegglin?
The May-Hegglin anomaly (MHA) is a rare autosomal dominant disease due to MYH9 gene mutation characterized by neutrophils with abnormal cytoplasmic inclusions, large platelets, and variable thrombocytopenia.
What is the result of May-hegglin anomaly in PAS staining?
The mutation results in disordered production of nonmuscle myosin heavy chain type IIA. This leads to macrothrombocytopenia secondary to defective megakaryocytic maturation and fragmentation. Leukocyte inclusions are precipitates of myosin heavy chains. Neutrophil and platelet function is considered to be normal [3].
What is MHA disease?
May-Hegglin anomaly (MHA) is an autosomal dominant disorder characterized by various degrees of thrombocytopenia that may be associated with purpura and bleeding; giant platelets containing few granules; and large, well-defined, basophilic, cytoplasmic inclusion bodies in granulocytes that resemble Döhle bodies (see …
Is GPS curable?
There is no specific treatment for GPS, but management involves anticipating and preventing risks of bleeding (e.g. possible platelet transfusions before surgery). Treatment may also include administration of desmopressin.
What is Quebec platelet disorder?
Quebec platelet syndrome (QPS) is a platelet granule disorder characterized by moderate to severe bleeding after trauma, surgery or obstetric interventions, frequent ecchymoses, mucocutaneous bleeding and muscle and joint bleeds.
Is pancytopenia curable?
Most cases of pancytopenia are minor and often due to nutritional deficiencies. In many cases, these are treatable and not serious. However, a more serious condition could be responsible.
What is treatment for pancytopenia?
Treatments for pancytopenia include drugs that suppress the immune system (immunosuppressant drugs) and bone marrow stimulant drugs, blood transfusion, bone marrow transplant, and stem cell replacement therapy. In some cases, symptoms of pancytopenia can be severe or life-threatening.
Is there any treatment for May-Hegglin anomaly?
In mild cases, treatment for May-Hegglin anomaly is not usually necessary. In more severe cases, transfusions of blood platelets may be necessary. May-Hegglin anomaly is a rare blood platelet disorder that affects males and females in equal numbers.
What is May Hegglin anomaly MHA?
May Hegglin Anomaly The May-Hegglin anomaly (MHA) is a rare autosomal dominant disease due to MYH9 gene mutation characterized by neutrophils with abnormal cytoplasmic inclusions, large platelets, and variable thrombocytopenia. It is part of myosin heavy chain (MHC) single gene defect group that also includes Fechtner …
Do people with May-Hegglin anomaly need blood transfusions?
There also might be fewer platelets than normal (mild thrombocytopenia). In severe rare cases, people with May-Hegglin Anomaly may require transfusions of platelets. People with Chediak-Higashi Syndrome, a form of Albinism, have cellular inclusions that are very similar to those of May-Hegglin Anomaly.
When is a hematologist consulted in the treatment of May Hegglin anomaly?
A hematologist should be consulted to assist in the management of patients who are undergoing surgery or vaginal delivery and patients who have experienced severe trauma. Fatima S. May hegglin anomaly: rare entity with review of literature. Indian J Hematol Blood Transfus. 2012 Mar. 28 (1):58-60.
