DAMASCENO, Juliana Annete et al. Parvovirus and severe anemia in an immunocompetent patient. J. Bras. Patol. Med. Lab. [online]. 2012, vol.48, n.2, pp.117-120. ISSN 1676-2444.

A 16-year-old human immunodeficiency virus (HIV) negative male patient without hematological disease developed acute anemia due to parvovirus B19 infection. The disease showed a biphasic evolution: clinical remission and return of symptoms after 15 days. Physical examination revealed paleness and fever, neither adeno nor organomegalies, and signs of heart failure. The bone marrow aspiration showed megaloblasts with aberrant nucleoli. As far as histology is concerned, giant cells with aberrant nucleoli and the presence of intranuclear inclusions typical of Parvoviruses were observed. Immunohistochemistry revealed positivity for specific Parvovirus antibody. Serology confirmed parvovirus B19 infection.
