Metastases to extraocular muscles from breast cancer: case report and up-to-date review of the literature.

BACKGROUND: Unilateral or bilateral metastases to extraocular muscles are very rare in breast cancer. CASE PRESENTATION: We describe a case of inferior rectus extraocular muscle involved by ductal luminal B/Her-2 neu negative breast cancer, observed in a cohort of 580 patients. Our patient had received chemotherapy and hormonal therapy (tamoxifen for 3 years and letrozole in the following 3 years) for her primary cancer and developed an orbital metastasis while she was under aromatase inhibitor-based therapy. Diagnosis was confirmed by MRI and biopsy. Orbital radiotherapy, combined with fulvestrant, resulted in shrinking of the secondary mass. A third line hormonal therapy using palbociclib was then started. Twelve-months later, MRI showed no residual tumor mass. Currently, the patient is alive and in good general conditions after 20 months. CONCLUSIONS: Literature review yielded 57 patients with extraocular muscle metastases from breast cancer, mostly due to the invasive lobular subtype of carcinoma. In addition to the present case, only 4 other extraocular muscles metastases from invasive ductal carcinoma has been reported, pointing out to the rarity of ductal type spread to the orbit in the natural history of breast cancer. Surgery may be used as a single treatment, despite no improvement of symptoms. Radiotherapy alone or combined with chemotherapy, or with chemotherapy plus hormonal therapy are available options. Results are, however, missing or poor. The present case is the first one with complete and stable response after 20 months to radiotherapy, antiestrogen drug fulvestrant and selective inhibitor of CDK4 /CDK6 palbociclib. In this subset of patients, with unusual metastatic sites and frequent multi-organ metastatic impairment, a multidisciplinary approach is indicated in order to achieve the best therapeutic management and long-term surveillance.

Laparoscopic stripping versus endometrioma ethanol sclerotherapy in women with endometrioma awaiting IVF: a long-term analysis of ovarian reserve and pregnancy outcome.

BACKGROUND: The aim of this study was to compare ovarian reserve, oocytes quality and pregnancy outcome of endometrioma treatment by laparoscopic stripping (LS) versus endometrioma ethanol sclerotherapy (EST) in infertile women awaiting in-vitro fertilization (IVF). METHODS: Retrospective analysis was performed. Twenty-three women underwent EST and 26 women LS. Intra- and postoperative complications were recorded. The women were followed-up for 36 months for cyst recurrence, oocytes quality and pregnancy outcome. Serum anti-Müllerian hormone (AMH) levels after treatment were measured to observe the impact on the ovarian reserve. Women's satisfaction was investigated with PGI-I. RESULTS: During follow-up, there were 3 endometriomas recurrences after LS and none after EST. Six months after treatment AMH was 3.17±2.15 in EST vs. 2.22±1.97 in LS, P=0.045. Symptoms' improvement was comparable. No intraoperative complications occurred. In the LS group the postoperative complications were significantly higher. After IVF cycles, the quality of the retrieved oocytes was the same. In EST group, clinical pregnancy (48.1% vs. 19.6%) and live birth rates (36.5% vs. 14.3%) were significantly increased compared to LS. Women's satisfaction was comparable at PGI-I. Both EST and the presence of an endometrioma sized 6 cm or less proved to be independent factors of a better live birth rate in multivariate analysis. CONCLUSIONS: EST efficacy was greater than LS for endometrioma. Ovarian function was well preserved. Hospital stay was shorter, fewer complications occurred. Pregnancy outcome was better after EST.

Mature Ovarian Teratoma: Neurological Implications in a Young Woman.

Anti-NMDAR encephalitis is an autoimmune syndrome associated with antibodies against NMDA receptors. In some cases, it is associated with various tumors; one of them is ovarian teratoma, which mostly affects women below the age of 30 years. Here, we report a case of ovarian teratoma associated with anti-NMDAR encephalitis treated with both laparoscopic surgery and immunotherapy. Multidisciplinary approach is the cornerstone for the management of this syndrome.
