Introduction
PWCA is an haematologic disorder characterized by agranulocytosis with
absence of myeloid precursors in bone marrow with an eritropoiesis and
megacariopoiesis preserved. It has been associated with drugs,
infectious diseases and autoinmunity1. Thymomas and
thymic carcinomas may present autoinmune phenomena fundamentally:
miastenia gravis (MG) up to 50% of the cases and pure red cell aplasia
(PRCA) up to 5% of the cases 2. However, the
incidence of thymoma and PWCA is extremly rare by existing few
reports3.
