Malacoplakia of the Uterine Cervix: A Case Report

Adela Saco et al. Pathogens. .

Abstract

Malacoplakia is an uncommon chronic granulomatous inflammation that rarely affects the female genital tract. A case of a 78-year-old woman with malacoplakia involving the uterine cervix and the vagina is described. The patient complained of vaginal bleeding. Clinically, a 13-mm mass was detected in the cervix, which was confirmed by ultrasound scan and magnetic resonance imaging. Histological examination showed a dense histiocytic infiltrate with abundant Michaelis-Gutmann bodies involving the uterine cervix and the upper vagina. The presence of Escherichia coli was confirmed in the lesion by immunohistochemistry and polymerase chain reaction. Only 12 cases of cervical malacoplakia have been reported to date. This condition should be included in the differential diagnosis of cervical tumors.

Keywords: Michaelis–Gutmann bodies; inflammatory pathology; malacoplakia; uterine cervix.

Pelvic magnetic resonance imaging (MRI). An infiltrative cervical mass (arrow) is seen in axial (A) and sagittal (B) T2 weighted MRI with stromal infiltration as a disruption of the cervical stroma hypointensity and focal infiltration of superior vaginal third (arrow in A). The lesion showed restricted diffusion in high b value (C: DWI b 800) and contrast enhancement (D: Post-contrast axial T1w fat saturated MRI).
