Parvovirus B19-triggered Acute Hemolytic Anemia and Thrombocytopenia in a Child with Evans Syndrome.

Background: Human parvovirus B19 (HPV-B19) is the etiologic agent of erythema infectiosum, of transient aplastic crises in individuals with underlying chronic hemolytic disorders, and of chronic pure red cell aplasia in immunocompromised individuals.

Case Report: We describe a 14-year-old girl with long-standing Evans syndrome, who presented with severe anemia, reticulocytopenia and thrombocytopenia. A bone marrow aspirate revealed severe erythroid hypoplasia along with the presence of giant pronormoblasts, while serological studies and real-time PCR of whole blood were positive for acute parvovirus B19 infection.

Extensive cutaneous anthrax in an immunocompetent patient.

Bacillus anthracis disease constitutes an extremely important worldwide epidemiological problem. Interest in cutaneous anthrax resides in its skin manifestations, course, diagnostic methods and management. An extensive cutaneous anthrax of the whole left upper arm, accompanied by lymphadenopathy and high fever, in a 60 year-old male patient, a shepherd by profession, is reported.
