The ear in the acquired immunodeficiency syndrome: I. Temporal bone histopathologic study.
A postmortem histopathologic investigation of temporal bones of patients with the acquired immunodeficiency syndrome (AIDS) was performed after microslicing, acid decalcification of the slices and paraffin embedding. Histopathologic changes in 49 temporal bones from 25 patients included severe otitis media in five patients (20%), low-grade otitis media in fifteen (60%), labyrinthine cryptococcosis in two, Kaposi's sarcoma deposit in the eighth nerve of one, and cytomegalovirus (CMV) inclusion-bearing cells in the inner and middle ear of six (24%). It was possible to identify the CMV genome by in situ hybridization in only two bones and expression of CMV antigen by immunohistochemistry in none, probably because of prolonged decalcification in acid. The ear is no less susceptible to AIDS-associated diseases than any other organ, and is particularly prone to CMV infection.
