An unusual orbital metastasis of breast cancer.

In this paper we report the clinical case of a 84 year old female patient with a history of breast cancer diagnosed 14 years before, treated only with hormone therapy for 10 years and with subsequent follow-up oncology which always demonstrated negative results. 14 years after the first diagnosis, the patient presented with an increase in mass markers (CEA), and progressive symptoms of the right eye (diplopia). A CT scan and an MRI of the orbits confirmed the presence of an expansive neoplastic formation of the right orbit of 16 × 9 mm. The orbital metastases are rare locations of metastatic breast cancer which pose problems of differential diagnosis and require prompt and multimodal treatment (chemotherapy, hormone therapy, radiation therapy) aimed at improving the quality of life of the patient.

Matrix-producing carcinoma of the breast: a case report.

Matrix-producing breast cancer (MPC) is a subtype of metaplastic carcinoma of the breast. It is a very rare tumor, which constitutes less than 1% of all malignant mammary tumors. The origin of this tumor is still unclear: there are molecular studies that suggest an origin from myoepithelial cells, whereas other studies underline the neoplastic transformation of a multipotent stem cell. Even the differential diagnosis of MPC and other breast neoplasms (phyllodes tumors and real sarcomas of the breast) is not always easy. In the literature, a certain chemoresistance has been demonstrated, and a standard treatment of this tumor does not exist at this time. We report the case of a 44-year-old, premenopausal, female patient with a 6-cm breast lump. Neither imaging nor fine needle aspiration biopsy was crucial in achieving a diagnosis. The patient underwent a simple mastectomy. In consideration of the negative lymph node status, the patient was not subjected to radiotherapy or adjuvant chemotherapy. Moreover, since the receptor status was negative, hormone therapy was not necessary. The patient has been disease free for 4 years now.

[Quadrantectomy and removal of the sentinel lymph node under local anaesthesia in the day hospital setting]. / Quadrantectomia e asportazione del linfonodo sentinella in anestesia locale in day hospital.

In recent years, breast carcinoma diagnostics and therapy have evolved very considerably, allowing conservative surgery in most cases. These kinds of major operations have been greatly simplified since the introduction of the sentinel lymph node approach, with the possibility of a day surgery operation under local anaesthesia. The aim of this study, after thorough analysis of the axillary lymph nodes with ultrasound and cytological examinations, was to assess whether it would be possible to distinguish between negative and metastatic lymph nodes and whether the operation could be performed under local anaesthesia without hospitalisation. From January 2005 to January 2007, 54 breast carcinoma patients with negative axillary lymph nodes (after ultrasound examination) had a quadrantectomy and sentinel lymph node removal under local anaesthesia together with sedation where appropriate. Eight patients who presented micrometastases or isolated tumour cells in the sentinel lymph node underwent a subsequent lymphadenectomy. Our data show that, thanks to thorough analysis of the axillary cavity, it may be possible to use the sentinel lymph node approach with a good chance of the patient remaining free of distant metastases and of operating under local anaesthesia.
