[Ovarian Burkitt lymphoma as the primary manifestation: A case report and literature review].

Ovarian involvement as the initial manifestation of a Burkitt lymphoma without detectable extra-ovarian disease is rare, which is why it is usually not included in the differential diagnosis when an ovarian tumor is detected. A missed diagnosis will lead to the wrong treatment being given, and this can compromise any future reproductive wishes of the patient. In this article, a patient presents a Burkitt lymphoma with ovarian involvement as an initial manifestation and an unusually rapid systemic progression of the disease.

[Non-surgical management of rectovaginal fistula: a case report].

Background: The rectovaginal fistula is a rare disease whose treatment is extremely difficult.

Objective: To present the expectant management of rectovaginal fistula as an alternative to surgery for those cases in which the surgical risk is not an acceptable option.

Clinical Case: We report the case of a rectovaginal fistula in an 85-year-old woman with significant comorbidity that avoided the performance of any surgical technique.
