The clinicopathological significance of cytomegalovirus inclusions demonstrated by endocervical biopsy.
A healthy 20 yr old woman presented for evaluation following a cervical smear which showed viral effects typical of human papilloma virus. Colposcopy showed changes of cervicitis with the main finding on histologic examination of biopsy material being an acute and chronic cervicitis associated with typical features of cytomegalovirus (CMV) infection. Viral identification was confirmed by immunoperoxidase staining, in situ hybridization and electron microscopy. The patient was lost to follow up for 18 mths. Following this, a repeat colposcopy again showed inflammation, with cervicitis, mild dysplasia and CMV inclusions on biopsy. Full immunological work-up, including human immunodeficiency virus (HIV) study, was performed and was normal. Only 11 other cases of endocervical biopsies with histological evidence of CMV inclusions were found in the literature, although the reported rate of detection of genital CMV in women on culture is 4-12%. In the 9 cases where information was available, endocervical inflammation was present. One patient was on immunosuppressive medication for systemic lupus erythematosus and another was found to have Acquired Immune Deficiency Syndrome (17% of total). These cases demonstrate that although histologic examination is an insensitive marker for CMV within the cervix, its presence may signify immunodeficiency and so immunological assessment of a patient with this finding is advisable.
