RESUMO
OBJECTIVES: Isolated axillary lymph node metastases is an unusual clinical presentation of breast carcinoma. We studied its different issues. METHODS: This study is a follow-up study of 16patients, treated between 1996 and 2012, presenting with axillary metastases with an occult breast carcinoma, which could not be identified by physical examination nor by a conventional imaging or a breast MRI. Clinical characteristics, histological analysis, treatment, monitoring and five-year survival rate were studied. RESULTS: The incidence of this kind of breast cancer was 0.20%. A breast MRI was performed in 75% of the patients. The histology of these tumors showed a rate of hormono-sensibility of 50% and an HER2 overexpression of 44%. Sixty-nine percent of the patients had no breast surgery or radiotherapy; global five-year survival rate for these women was 77.4%±11.5. CONCLUSION: The survival rates of this study should lead the practitioner to choose a less aggressive breast therapy. Moreover, the histological characteristics explain the high metastatic potential of these tumors, and relate them to the HER2+ subclass of gene expression patterns of breast carcinomas.

Chemotherapy is the reference treatment for gestational trophoblastic neoplasia. In case of chemoresistance, hysterectomy has to be considered even in women wishing to conceive. A 31-year-old nulliparous patient presented a recurrent invasive mole, despite two regimens of chemotherapy. She underwent a partial uterine resection of an intramyometrial choriocarcinoma followed by a third-line regimen. Two years later she gave birth by cesarean section at 32 weeks of amenorrhea to a healthy child after a spontaneous pregnancy. In order to preserve patient's fertility, conservative uterine surgery is an alternative to hysterectomy for selected chemoresistant gestational trophoblastic neoplasia.
