[Atypical urticaria disclosing acute basophilic leukemia. Apropos of a case associated with hyperhistaminemia]. / Urticaire atypique révélatrice d'une leucémie aiguë à basophiles. A propos d'un cas associé à une hyperhistaminémie.

ABSTRACT

Acute basophilic leukaemia (ABL) is a rare disease characterized by high fever, anaemia and haemorrhagic diathesis. Its prognosis is somber and its response to therapy mediocre. Death is mainly due to cerebral or digestive hemorrhage and coronary disease. In a very small number of cases ABL, like all diseases accompanied by an increase in basophils, may be associated with hyperhistaminemia responsible for cutaneous and gastric symptoms.
