Paratubal Cyst Recurrence in Children and Adolescents.

Abstract

To examine the association between patient characteristics and risk for recurrence risk of paratubal cysts (PTC) in children and adolescents. Retrospective chart review at a single institution. Single academic children's hospital. Pediatric patients presenting to Texas Children's Hospital between July 2007 and March 2019. Patients were identified for the study by reviewing pathology reports and were included if they met inclusion criteria of a pathologic diagnosis of a paratubal or paraovarian cyst removed during any surgical procedure between July 2007 and March2019. Subjects with pathologic diagnoses of a paratubal cyst during the study period underwent chart review for the following data points: age at presentation, ethnicity, pathologic recurrence of paratubal cysts, pubertal status, body mass index (BMI), diagnosis of polycystic ovary syndrome (PCOS), size of cyst, laterality of cysts, and number of cysts. Recurrence, Pathology types. Of the 627 patients that met inclusion criteria, the incidence of recurrence was 11.3%. Group 1 included those with recurrence of PTC (N=70). Group 2 was identified as those without recurrence of PTC (N=557). There were no differences related to age, BMI, ethnicity, history of PCOS, cyst size, laterality or number of cysts present. PTC NOS and serous PTC occurred most frequently. Of the unique cases involving recurrence, 70.1% recurred on the ipsilateral side. There were no cases of paratubal cyst malignancies in this cohort. The range of pathology diagnoses included pathologies that may occur in ovarian cysts. This is particularly interesting, given the known origins of ovarian cancer from fallopian tube transformations. Rare pathology diagnoses likely did not occur with frequency to determine definitive risks of recurrence in these cases. There appears to be a baseline recurrence risk for PTC, for which patients can be counseled. Recurrence does not appear to be associated with any particular pathology type, cyst size, number of cysts, BMI, PCOS, or puberty stage. Recurrence, should it occur, appears to occur more commonly on the ipsilateral side.
