Intraneural perineurioma in a child with Beckwith-Wiedemann syndrome.

To the authors' knowledge, this is the first report of an intraneural perineurioma in a child with Beckwith-Wiedemann syndrome. Intraneural perineurioma, previously known as localized hypertrophic neuropathy, is a rare benign peripheral nerve sheath tumor arising from perineurium. This report adds a new entity in the spectrum of tumor formation in Beckwith-Wiedemann syndrome.

Cardiac aspergillosis in patients with acquired immunodeficiency syndrome: a case report and review of the literature.

Cardiac aspergillosis is uncommon in patients with acquired immunodeficiency syndrome (AIDS) in the absence of open heart surgery. We report a unique case of a 62-year-old man with AIDS who developed Aspergillus pancarditis with Aspergillus vegetations on mitral valve without evidence of pulmonary aspergillosis. There was extensive embolization to the brain and multiple foci of Aspergillus infection in kidneys and adrenal glands. There are only 10 documented cases of cardiac aspergillosis in the literature (1966-2003) in severely immunocompromised AIDS patients with CD4 T-lymphocyte counts ranging from 10 to 121 cells/muL. The cardiac aspergillosis could result from invasive pulmonary aspergillosis, either by hematogenous dissemination or by direct invasion, and skin Aspergillus infection can be carried through the bloodstream to the right heart in intravenous drug abusers. Most of the reported cases of cardiac aspergillosis were diagnosed at autopsy. Mortality among AIDS patients with cardiac aspergillosis is 100%, despite appropriate therapy.
