Malakoplakia of endometrium with osseous metaplasia on evaluation of postmenopausal leukorrhea: A rare case report

Abstract

Malakoplakia is a chronic xanthogranulomatous condition that affects the genitourinary tract reported earlier as urinary granulomas and pelvic masses. We report a different clinical manifestation of malakoplakia presenting as postmenopausal pyometra. A 64-year-old postmenopausal female presented with foul-smelling vaginal discharge with a past history of induced abortion, followed by dilatation and evacuation. On examination, abdomen was soft, vaginal examination revealed pus discharge, parous size uterus with free fornices, and pap smear ruled out malignancy. Ultrasonography revealed linear, echogenic structures in the endometrial cavity suspicious of bony spicules with fluid around. Hysteroscopy revealed congested endometrium with multiple pieces of shredded bone-like structures that were removed followed by curettage. Histopathological examination was suggestive of malakoplakia with osseous metaplasia. Retained bony spicules can cause chronic granulomatous inflammation that may become symptomatic postmenopause due to absent cyclical shedding. This is the first reported case of malakoplakia of uterus following retained bony spicules.
