A,C,D,E,F aint the ans. 2 to go. pure rbc aplasia? due to thymoma. and renal cell ca. renal cell ca will produce erythropitin and pt will have raised rbc count. but in case of thymoma pt can present with weaknes and dyspnea and pallor. only thing to be asked is why she has no jaundice developed? still i think B is a reasonable ans.

b.-Thymic tumor is the right answer cos a very few present with Pure REd Cell Aplasia which is the clinical picture here. Although not a very prominent finding but th epts do present with Weakness and only 5% will have Pure Red Cell Aplasia The REst of the Choices Cause Polycythemia

 B Pure red cell aplasia(PRCA) is a rare form of marrow failure characterized by marked hyoplasia of marrow erythroid elements in the setting of normal granulopoiesis and thrombopoiesis. PRCA is associated with Thymoma and Parvovirus B19 infection
