Essential Thrombocytosis in a Postmenopausal Female a Rare Cause of Aquagenic Pruritus

Abstract

Essential thrombocytosis (ET) is a hematopoietic stem cell disorder in which the overproduction of platelets without a definable cause occurs. Its incidence is 1–2 per 100,000 population with female preponderance. These myeloproliferative disorders are associated with many dermatological manifestations such as pruritus and erythromelalgia. Here, we are reporting the case of a 61-year-old female with ET with aquagenic pruritus (AP), although AP is associated more with polycythemia vera.
