Endometrial Metastasis from Ductal Breast Carcinoma: A Case Report with Literature Review

Uterine Metastasis Presenting as Abnormal Uterine Bleeding in a Case of Primary Breast Cancer Identified on 18F-FDG PET/CT

Metastases to the female genital tract are rare, especially from extragenital primaries. The most common extragenital sites associated with genital metastasis are the gastrointestinal tract (37.6%) followed by the breast (34.9%). It is crucial to differentiate primary from metastatic involvement of the uterus for appropriate patient management. We present one such case of endometrial metastasis in a patient who presented clinically with abnormal uterine bleeding and was diagnosed with primary breast cancer via 18F-FDG PET/CT.

An Unusual Occurrence of Uterine Metastases in a Case of Invasive Ductal Breast Carcinoma

Breast cancer is the most frequent cancer in women and has a high proclivity for metastasizing, yet it seldom affects gynaecological organs. We present a case of invasive ductal carcinoma of the breast that metastasized to the uterus following initial curative treatment. Our patient was taking tamoxifen, which can induce endometrial hyperplasia and make diagnosis more complicated.

Uterine metastasis from invasive ductal breast carcinoma: A case report with literature review

Breast cancer is the leading cause of cancer death in women, and most breast cancer related deaths are due to metastases. Uterine metastases from breast cancer are uncommon and rarely reported in the literature. We described the case of a 50 years-old-woman who developed a uterine metastasis, 6 years after the diagnosis of an invasive ductal breast carcinoma. Indeed, although the patient was asymptomatic, the monitoring imaging examinations, particularly the computed tomography (CT) and the positron emission tomography/computed tomography (PET/CT), showed a myometrial lesion. Non-conservative total hysterectomy was performed. The anatomo-pathological examination revealed a myometrial metastasis from an invasive ductal breast carcinoma. Seventeen months after surgery, the patient had no pelvic recurrence, but lungs and bones metastases progressed despite chemotherapy. In the lack of guidelines of uterine metastases from breast cancer's management, we reviewed the existing literature with the aim to provide a rational framework for clinical presentation, diagnostic approach, histological findings and treatment of this rare and heterogeneous pathology. Uterine metastases of breast cancer are frequently revealed with metrorrhagia. They occur preferentially in tumours with initial lobular carcinoma, initial lymph node involvement and positive hormonal receptors.
