Endometrial stromal nodule: A rare case report

Abstract

Introduction: Endometrial stromal tumors represent less than 2% of uterine tumors, they are among the least common neoplasms of the uterine body. They can be divided into four main categories: endometrial stromal nodule, low-grade endometrial stromal sarcoma, high-grade endometrial stromal sarcoma and undifferentiated uterine sarcoma. This paper describes the case of a patient with a diagnosis of endometrial stromal nodule. Clinical case: A 50-year-old female patient, who reported the onset of the disease in March 2022, characterized by abnormal uterine bleeding with anemia and increased abdominal volume, for which she went to a foreign physician, where they indicated paraclinical tests. On July 12, 2022, he presented abdominal pain of sudden onset of moderate to severe intensity. Which is why she came to our center. Anemia and leukocytosis are determined. Imaging studies report a voluminous mass, mixed density, well delimited. Another hyperechoic lesion, which corresponds to a unicameral cyst of the right ovary. Surgical resolution was decided by performing an exploratory laparotomy + endometrial protocol, with satisfactory evolution of the patient. Conclusion: Hysterectomy is the treatment of choice. The anatomopathological study is fundamental for its final diagnosis and differentiation of stromal sarcomas, since its prognosis, treatment and follow-up are different.
