Primary extra nodal gynaecological lymphomas are rare, but their diagnosis is crucial since their treatment differs from the treatment of primary gynaecological malignancies. Throughout presentation of three case reports and a literature review, clinical, radiologic, pathologic and therapeutic aspects of primary extra nodal gynaecological lymphomas will be discussed. The first case is about a 50-yearsold woman diagnosed with a cervical DLBCL successfully treated with R-CHOP chemotherapy. The second case concerns 30-years-old, 3G 0P, woman diagnosed with endometrial lymphoma after a third spontaneous miscarriage. The third is an 80-years-old woman diagnosed with right breast cancer and simultaneous left MALT lymphoma. Large homogenous masses and unusual presentation mode, especially among young patients, should raise the attention towards lymphoma. Biopsy is the key examination for the diagnosis of lymphoma. Once primary extranodal gynaecological location is confirmed, treatment essentially consists of chemotherapy, with or without radiotherapy, and thus widely differs from the treatment of primary gynaecological tumors.
Breast cancer is the most frequently diagnosed malignancy and the leading cause of death in women [1]. A small portion of cases occur in young patients with 6.6% of all cases diagnosed below the age of 40 years, 2.6% below the age of 35 years and 0.65% below the age of 30 years [2]. Genetic and familial cancer syndromes are more prevalent in young patients compared to older counterparts. BRCA1 and BRCA2 mutations account for about 10% of all breast cancer cases in young women. Nevertheless, very early onset breast cancer might be the initial presentation of Li-Fraumeni syndrome (LFS). LFS is also known as sarcoma, breast, leukemia and adrenal gland (SBLA) cancer syndrome and is caused by the germline mutation of the TP53 gene, responsible for a wide spectrum of early-onset malignancies [3]. Its transmission is autosomal dominant with a prevalence of around 1/100000 in the general population and 1% of all breast cancers. Half of affected women will develop a cancer by the age 30 and the penetrance of the germline TP53 mutation reaches 100%. Breast cancer is the most common adult malignancy among patients with LFS [4]. Throughout this case report, we aim to illustrate clinical history and special considerations once the diagnosis of Li-Fraumeni syndrome is made. Case Description A 25-year-old primipara patient presented in May 2015 with a high grade invasive ductal carcinoma of the left breast (cT-2N1aM0). The hormonal receptors were positive, HER2/neu was amplified, and Ki-67 was expressed in 30% of tumor cells. She underwent anthracycline-based neoadjuvant chemotherapy with Trastuzumab and subsequently breast-conserving surgery with complete axillary lymph node dissection (ypT1bN0). The patient received adjuvant breast and axillary irradiation (64Gy), postoperative Trastuzumab and hormonal therapy by Tamoxifen and LHRH agonist. The patient's mother was diagnosed with breast cancer at age 44. Genetic testing for BRCA1 & 2 mutation was negative (Figure 1).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
