Mullerian adenosarcoma of the uterus with MASO: a case report of cervical adenosarcoma in a young female that never had sexual behavior.

BACKGROUND: Cervical mullerian adenosarcoma is a rare uterine sarcoma, especially in young women. Its pathological features are low-grade malignant tumors with bidirectional differentiation, and the degree of malignancy is similar to that of low-grade endometrial stromal sarcoma. This paper reports the case of a young asexual patient who has been closely followed up after tumor resection and has not had any recurrences. CASE PRESENTATION: A 20-year-old, young asexual woman was diagnosed with cervical mullerian adenosarcoma with sarcomatous overgrowth (MASO). Cervical tumor resection was performed after admission, and the resection margin was negative. After the operation, she refused to undergo secondary surgery due to fertility requirements and did not receive adjuvant treatment. The patient was closely followed up after the operation and has not yet relapsed. CONCLUSION: A young woman with cervical MASO did not receive adjuvant treatment after cervical tumor resection. For women with fertility requirements, close follow-ups should be conducted after the operation to guard against tumor recurrence and radical tumor resection should be performed as early as possible after the patient no longer requires their fertility.

Nonpuerperal uterine inversion caused by an adenosarcoma: A case report.

INTRODUCTION: Eighty-five per cent of uterine inversions are puerperal. Non-puerperal uterine inversion is usually caused by tumours that exert a traction force on the fundus of the uterus. This causes the uterus to be partially or completely inverted. It is commonly related to benign tumours like submucosal leiomyomas. Nevertheless, malignancies are an infrequent association. CASE PRESENTATION: We report a case of a 35-year-old female patient, medically and surgically free, gravida0 para0, complaining of menometrorrhagia associated with pelvic pain for 2 years. A suprapubic ultrasound scan showed an enlarged, globular uterus with a heterogeneous, undefined mass of 49 mm in size. MRI scan showed the appearance of a U-shaped uterine cavity and a thickened inverted uterine fundus with an endometrial infiltrating mass of 25 mm. Intraoperative exploration showed uterine inversion involving the ovaries; the fallopian tubes and the round ligaments and a necrotic intracavitary mass. The malignancy of the tumor was confirmed through anatomopathological examination as Adenosarcoma. CONCLUSIONS: Uterine inversion is rare outside the puerperal period, and malignant etiology must not be overlooked. Therefore, comprehensive care with meticulous etiological investigation is crucial.

Adenosarcoma de ovario asociado con elevación del antígeno sérico Ca-125: informe de caso y revisión de literatura / Ovarian adenosarcoma with elevated CA125 antigen: case report and literature review

BACKGROUND: Adenosarcomas are rare tumors usually derived from the endometrium. About 50 cases of adenosarcomas of the ovary have been reported. The relationship between adenosarcoma and CA125 has not been described. The authors present a case of adenosarcoma with elevated CA125 because of the unusual presentation of this pathology and also because elevation of the CA125 antigen has not been reported in the literature. CLINICAL CASE: A 42-year-old woman presented for consultation for incidental right ovarian tumor and CA125 of 1100 U/mL. Histology revealed a homologous Müllerian adenosarcoma of the right ovary with sarcomatous overgrowth. CA125 decreased to 16 U/mL after surgery. Sixteen months post-surgery, the patient is disease free and with normal CA125. DISCUSSION: Ovarian adenosarcomas are more aggressive than adenosarcomas of the uterus. Because of the embryological origin, ovarian adenosarcomas are able to produce CA125 antigen, especially in the presence of sarcomatous overgrowth. With these facts, CA125 antigen may be useful as a prognostic factor because it may represent an indirect marker of sarcomatous overgrowth. CONCLUSIONS: CA125 may be useful for follow-up of ovarian adenosarcomas. Elevated CA125 antigen in adenosarcomas of the ovary may be indicative of sarcomatous overgrowth and poor prognosis.
