Histopathologic examination revealed epidermal spongiosis and liquefactive necrosis of the upper dermis admixed with numerous amebic trophozoites (Figure 2). The trophozoites were identified by the eccentric small nuclei with a central karyosome and abundant cytoplasm with vacuolation and ingested erythrocytes (Figure 3). The patient was thought to have a disseminated cytomegalovirus infection and was treated with intravenous ganciclovir sodium for 2 weeks. She also received intravenous meropenem. Her condition deteriorated, however, and she died before the diagnosis of invasive amebiasis was made by means of histopathologic examination and tissue culture.
