  • Title: Concomitant malacoplakia and granuloma inguinale of the cervix in acquired immune deficiency syndrome.
    Author: Ramdial PK, Sing Y, Chotey NA, Bagratee JS.
    Journal: Int J Gynecol Pathol; 2008 Apr; 27(2):282-7. PubMed ID: 18317211.
    Abstract:
    We describe concomitant granuloma inguinale (GI) and malacoplakia of the cervix in 2 acquired immune deficiency syndrome (AIDS) patients aged 27 and 36 years. Both patients presented with a bloody foul-smelling vaginal discharge. Speculum examination confirmed cervical ulceration, prompting the diagnosis of cervical carcinoma in both patients. Cervical punch biopsies confirmed the characteristic features of GI; granulation tissue containing a dense plasma cell infiltrate, aggregates of neutrophils, and vacuolated enlarged histiocytes containing Donovan bodies were noted. Many of these histiocytes and sheets of von Hansemann cells contained intracytoplasmic Michaelis-Gutmann bodies, confirming concomitant malacoplakia. Michaelis-Gutmann bodies were also present in extracellular locations. Ultrastructural examination confirmed these histopathologic findings. One patient died of disseminated tuberculosis before treatment was initiated. The other patient did not return for a follow-up visit of her cervical lesion. Concomitant GI and malacoplakia is unreported in genital and extragenital sites; Klebsiella granulomatis must therefore be added to the list of bacteria associated with malacoplakia. Malacoplakia of the female genital tract is documented rarely and remains unreported, to date, in AIDS patients. Similar to the pathogenetic mechanisms described for AIDS-associated malacoplakia in extragenital sites, it is hypothesized that, in addition to abnormal macrophage functioning and an inability to degrade bacteria, special constituents of K. granulomatis are undigestable by lysosomal enzymes in human immunodeficiency virus-infected patients.
