Metastização uterina de carcinoma mamário – Relato de caso

Metastatic disease involving the uterus is rare. Typically it is the ovaries that are involved and the primary tumor is usually the breast or the gastrointestinal tract.

Case report

We describe a case of metastatic breast carcinoma involving the uterus in a patient who had had a bilateral mastectomy due to invasive carcinoma NOS more than thirty years ago. Histological assessment of the hysteroscopy biopsy specimen including immunohistochemistry staining confirmed the breast carcinoma as the primary lesion, however it was classified as lobular carcinoma. The patient refused surgery or other invasive procedures, having complied nevertheless to follow up with clinical and ultrasound evaluation.

Conclusion

Metastatic breast disease to the feminine genital tract is more frequently due to lobular invasive carcinoma. We present a case of uterine metastization of invasive lobular carcinoma more than thirty years since the primary tumor, which was classified as invasive carcinoma NOS and confirmed by histological revision. It is of great importance to give the pathologist the correct information about the patient, namely of any oncologic background, so differential diagnosis can be made.
