Pathologic features of necrotizing adenoviral prostatitis in an AIDS patient

Adenovirus has been implicated as a cause of opportunistic infections in immuno-compromised patients, frequently with multiorgan involvement and a fatal outcome. We describe a case of necrotizing adenoviral prostatitis in a 35-year-old man with terminal AIDS and generalized adenoviral infection. The histopathologic findings of intraacinar necrotizing inflammation, prominent viral nuclear inclusions in residual epithelium, and mild T-lymphocyte and macrophageal inflammatory reaction were observed in the prostate. The presence of adenovirus was confirmed by electron microscopy and immunohistochemistry. Squamous metaplasia was present in the surrounding acini. This case of adenoviral prostatitis appears to be the first report of its kind in medical literature and demonstrates another aspect of the diversity of organ manifestations seen in this infection. This lesion should be included in the differential diagnosis of necrotizing prostatic diseases.
