Vaginal tumours in childhood: a descriptive analysis from a large paediatric medical centre

Clinical Review: Prepubertal Bleeding

BACKGROUND

Prepubertal bleeding is a common presentation in the pediatric office and can be distressing for patients and families. A comprehensive approach to diagnosis and management allows clinicians to identify patients at risk for worrisome pathology and arrange timely care.

OBJECTIVE

We aimed to review the key features of clinical history, physical exam, and diagnostic workup of a child presenting with prepubertal bleeding. We reviewed potential pathologies requiring urgent investigations and management, such as precocious puberty and malignancy, as well as more common etiologies, including foreign bodies and vulvovaginitis.

CONCLUSION

Clinicians should approach each patient with the goal of excluding diagnoses that require urgent interventions. A thoughtful clinical history and physical exam can inform appropriate investigations to optimize patient care.

Vaginal yolk sac tumors in infants and children: A case report and literature review

A vaginal yolk sac tumor (YST) is a rare malignant germ cell tumor for infants and children, and it has been >50 years since the first case was reported. The treatment strategy has changed markedly in the past 50 years, from radical surgical treatment to conservative surgery combined with chemotherapy, and then to combined chemotherapy alone. The present study reports the case of a primary vaginal YST in a 13-month-old girl that was successfully treated by tumor resection combined with chemotherapy. The clinical symptoms, imaging features and treatment characteristics are described in detail, as well as the postoperative treatment. There was no local recurrence or metastasis for the 2 years of follow-up to date. A literature review was also conducted to investigate the clinicopathological features, treatment and prognosis of this tumor. Overall, surgery combined with bleomycin, etoposide and carboplatin combination chemotherapy can be an effective option for vaginal YST.

Primary vaginal endodermal sinus tumor in infants and children: experience from a tertiary center

Background

The objective of the study was to analyze the clinical features, treatment, and outcomes of primary vaginal endodermal sinus tumor (EST) in infants and children treated in a tertiary center.

Methods

Clinical data of patients with pathologically confirmed primary vaginal EST in our hospital from January 1997 to December 2017 were retrospectively reviewed and analyzed.

Results

A total of 21 patients were included in this study. The median age at diagnosis was 11 months (range, 4–44 months). The most common manifestations were abnormal vaginal bleeding, and a polypoid mass protruding from the vagina. Chemotherapy based on PEB (cisplatin, etoposide, bleomycin) regimen was given, and serum alpha-fetoprotein (AFP) levels dropped to normal levels after 2 to 4 cycles of chemotherapy (median, 2 cycles). After 3 to 13 cycles of chemotherapy, with a median of 5 cycles, 20 patients achieved complete remission (95.2%). The median follow-up time was 80 months (range, 4-281months). At the time of the last follow-up, 19 cases were alive without disease, and the survival rate was 90.5%.

Conclusion

Vaginal EST is a very rare malignant germ cell tumor and is sensitive to chemotherapy. Conservative surgery combined with PEB chemotherapy is an effective way of treatment. Serum AFP and imaging examinations can monitor the treatment response and recurrence.
