Recurrent mantle cell lymphoma in the uterine cervix: a case report.

BACKGROUND: Mantle cell lymphoma is one of several subtypes of non-Hodgkin lymphoma. Cervical relapse of non-Hodgkin lymphoma is a very rare condition that has a variable and nonspecific presentation and may resemble other neoplastic or inflammatory conditions. CASE PRESENTATION: Our patient was a 58-year-old Caucasian woman who experienced relapse of mantle cell lymphoma with cervical localization. She complained of postmenopausal vaginal bleeding, bladder pressure, and rapid growth of a cervical lesion. An irregular tumor mass of the cervix was visualized during gynecological examination, with findings highly suggestive of locally advanced cervical cancer. Surprisingly, the biopsies showed an extra nodal relapse of mantle cell lymphoma in the cervix. The rarity of this presentation and the scarcity of clinical studies make this type of recurrence very aggressive and difficult to treat. CONCLUSIONS: Obtaining a definitive histological diagnosis by biopsy or surgical resection and starting appropriate therapy are essential for recovery and treatment of these patients, even if the prognosis is poor.

Structural Variations of Vaginal and Endometrial Microbiota: Hints on Female Infertility.

Microbiota are microorganismal communities colonizing human tissues exposed to the external environment, including the urogenital tract. The bacterial composition of the vaginal microbiota has been established and is partially related to obstetric outcome, while the uterine microbiota, considered to be a sterile environment for years, is now the focus of more extensive studies and debates. The characterization of the microbiota contained in the reproductive tract (RT) of asymptomatic and infertile women, could define a specific RT microbiota associated with implantation failure. In this pilot study, 34 women undergoing personalized hormonal stimulation were recruited and the biological samples of each patient, vaginal fluid, and endometrial biopsy, were collected immediately prior to oocyte-pick up, and sequenced. Women were subsequently divided into groups according to fertilization outcome. Analysis of the 16s rRNA V4-V5 region revealed a significant difference between vaginal and endometrial microbiota. The vaginal microbiota of pregnant women corroborated previous data, exhibiting a lactobacilli-dominant habitat compared to non-pregnant cases, while the endometrial bacterial colonization was characterized by a polymicrobial ecosystem in which lactobacilli were exclusively detected in the group that displayed unsuccessful in vitro fertilization. Overall, these preliminary results revisit our knowledge of the genitourinary microbiota, and highlight a putative relationship between vaginal/endometrial microbiota and reproductive success.
