This paper reports two cases of endometrial osseous metaplasia, suspected by ultrasound and diagnosed/treated via hysteroscopy, and reviews literature suggesting it stems from stromal stem cell differentiation and superoxide dismutase deficiency.

The paper presents two clinical cases of endometrial osseous metaplasia in women referred for infertility and chronic pelvic pain, where transvaginal ultrasound showed hyperechogenic endometrial images. Hysteroscopy identified multiple floating osseous formations in the endometrial cavity, which were removed and whose histologic sections confirmed the diagnosis; one patient achieved a healthy full-term pregnancy 8 months later, while the other had two pregnancies ending in complete early abortions. The authors also review the literature from the prior 15 years and describe the condition as a differentiation disorder involving secondary endometrial stromal stem cells attributed to superoxide dismutase deficiency. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Objetivo: presentar dos casos y revisar la literatura acerca de la etiología de la enfermedad y los métodos utilizados para su diagnóstico. Casos clínicos: los casos fueron atendidos en el Hospital de San José, Hospital Universitario de referencia de tercer nivel de atención, a donde llegaron remitidas, por infertilidad y dolor pélvico crónico, dos pacientes. Sus ecografías mostraban imágenes hiperecogénicas en endometrio. Se les realizó histeroscopia, encontrando múltiples formaciones óseas flotantes en cavidad endometrial, extraídas con pinza grasper, cuyos cortes histológicos confirmaron el diagnóstico de metaplasia ósea endometrial. La primera mujer quedó en estado de embarazo 8 meses después de la intervención, finalmente tuvo un recién nacido a término sano. La segunda mujer inició dos embarazos que terminaron en abortos tempranos completos. Materiales y métodos: se realizó una búsqueda electrónica en las bases de datos Medline vía PubMed, SciELO y Ovid, en donde se incluyeron artículos publicados en los últimos 15 años. Conclusión: la metaplasia ósea es un problema de diferenciación celular, de las células madre estromales del endometrio secundario, a raíz de una deficiencia de superóxido dismutasa. Esta entidad se sospecha por ecografía transvaginal y se debe diagnosticar y tratar con histeroscopia.Objective: presenting two cases and reviewing the pertinent literature concerning the methods used in diagnosing the entity and its etiology. Clinical cases: the cases were attended in the third-level San José teaching hospital where they had been referred due to infertility and chronic pelvic pain. Their echographies revealed hyperechogenic images in the endometrium. Hysteroscopy was performed, revealing multiple osseous formations floating within the endometrial cavity; these were extracted with grasper tweezers and their histological sections confirmed a diagnosis of osseous metaplasia of the endometrium. The first woman became pregnant 8 months later, delivering a healthy newborn at full-term; the second woman became pregnant twice but her attempts ended in complete early abortions. Materials and methods: a search was made of MEDLINE databases via PUBMED, SciELO and Ovid, including articles published during the last 15 years. Conclusion: osseous metaplasia is a cause of infertility involving cellular differentiation of secondary endometrial stromal (stem) cells leading to superoxide dismutase deficiency; this is suspected by transvaginal echography (ultrasound) and should be diagnosed and treated with hysteroscopy.
