Onyalai (Pronunciation: ō′nē-al′ā-ē) is a form of thrombocytopenia that affects some of the population in areas of central Africa.

[1]  Onyalai exhibits similarities to idiopathic thrombocytopenic purpura (ITP) but differs in pathogenesis.

Although the cause of onyalai is not known at this time, inadequate nutrition and/or the consumption of tainted food are suspected.

[1] Onyalai is an acute disease that results in the development of hematoma on oral mucous membranes.

Epistaxis, petechiae and ecchymoses are common symptoms, as are subconjunctival bleeding and menorrhagia.
