In PRCA, the [[bone marrow]] ceases to produce red blood cells. ==Causes== Pure red cell aplasia is regarded as an [[autoimmune disease]]. It may also be a manifestation of [[thymoma]]. It may also be as a result of viral infections such as [[HIV]], [[Herpes simplex virus|herpes]], [[parvovirus B19]] ([[Fifth disease]]), or [[Hepatitis#Viral|hepatitis]]. Association of pure red cell aplasia with T large granular lymphocyte leukemia is also well recognized, especially in China.<ref>{{cite web |url=http://jcp.bmj.com/cgi/content/abstract/51/9/672 |title=Association of pure red cell aplasia with T large granular lymphocyte leukaemia -- Kwong and Wong 51 (9): 672 -- Journal of Clinical Pathology |accessdate=2007-11-07 |format= |work=}}</ref> Many cases of PRCA are considered [[idiopathic]] in that there is no discernible cause detected. It can be associated with the administration of [[erythropoietin]].<ref name="pmid15459301">{{cite journal |author=Bennett CL, Luminari S, Nissenson AR, ''et al'' |title=Pure red-cell aplasia and epoetin therapy |journal=[[N.
