| Summary points: | A 33-year-old woman is admitted to an outpatient endoscopic unit with a history of secondary infertility and with a regular menstrual cycle. She reported a miscarriage at 12 weeks of gestation 7 years previously and subsequent dilatation and curettage in another medical facility. No examinations were performed until this admission, when the patient presented complaining of secondary infertility. Vaginal ultrasound, biopsy, pathological findings, and diagnostic and operative hysteroscopies are described. The authors discuss an endometrial ossification associated with secondary infertility after a miscarriage at 12 weeks, suggesting osseous metaplasia, and present a literature review. |
