Report of Three Cases of Osteoid Metaplasia of the Endometer at the CampusTeaching Hospital in Lome

Introduction: Endometria Osteoid Metaplasia (EOM) is a rare case characterized by the presence of bone tissue in the endometrium. It is a pathology poorly known, insufficiently researched and consequently little diagnosed and poorly treated It is often diagnosed when exploring a female secondary infertility. Patients and methods: We reported three cases of osteoid metaplasia of the endometrium observed at the Obstetrics and Gynecology Clinic of the Lome University Hospital. Two cases concern a 30 and 26-year-old nulliparous primigest women who had consulted for secondary infertility the first in 2015 and the second in 2016. The third patient, aged 32, was examined in January 2017 for pelvic pain and menorrhagia. The transvaginal ultrasound had noted in all patients a highly echogenic persistent, and linear in uterus cavity image with a posterior shadow cone. Diagnostic and surgical hysteroscopy were performed in all patients. The first started a spontaneous pregnancy in 2016 after treatment; this pregnancy ended in spontaneous miscarriage at 13SA. Then she conceived spontaneously in 2017 and carried this pregnancy to its term with a baby boy born vaginally. The second was nowhere to be found after a first clinical checkup that was normal. The third woman had a cessation of the menometrorrhagia and pelvic pain. Conclusion: Osteoid metaplasia of the endometrium is real fact in Togo. All the patients had abortion history voluntary or not. The transvaginal ultrasound and Hysteroscopy were used for diagnostic and the treatment. We got good results with surgical hysteroscopy.
