ABSTRACT
INTRODUCTION: Ovarian cancer has few subjective symptoms, so approximately 40%-50% of cases have already reached stage III or IV by the time of diagnosis. These are advanced stages of the disease and have poor prognosis. Among these cases, less than 3 % are reported to exhibit inguinal lymph node metastasis. This report documents a rare case of advanced ovarian cancer that we detected due to an inguinal metastasis in the canal of Nuck. The work has been reported in line with the SCARE criteria. PRESENTATION OF CASE: The patient was a 43-year-old, married, premenopausal woman (G2P1). She was examined by her local practitioner for a chief complaint of a mass in the right inguinal region and was found to have a right inguinal mass. Magnetic resonance imaging (MRI) scans revealed a left ovarian tumor, and she was referred to our department. Rapid intraoperative diagnosis showed a highly atypical serous carcinoma present in both the left ovary and the right inguinal region mass, where the tumor had extended into the canal of Nuck. DISCUSSION: In this case, the right inguinal mass was ovarian cancer that had metastasized to a cyst in the canal of Nuck via the round ligament of the uterus. Though, many adult women with these types of inguinal hydrocoeles sometimes undergo fine-needle aspiration. CONCLUSION: This finding may highlight the need for a careful search for metastasis to the inguinal region in cases of ovarian cancer.
ABSTRACT
AIM: To examine the effect that human papillomavirus (HPV) vaccination has had in Akita Prefecture, by comparing cervical cytology results from women aged 20-24 years with or without HPV vaccination. METHODS: We examined cervical cytology results from 2425 subjects who underwent cervical cancer screening under the jurisdiction of the Akita Foundation for Healthcare between January 2014 and October 2016. We compared the prevalence of cytologic abnormalities among women aged 20-24 years with or without HPV vaccination. RESULTS: The rate of atypical squamous cells of undetermined significance (ASC-US) or worse was 0.242% (1/413) with HPV vaccination, and 2.04% (41/2012) without HPV vaccination. Overall, the prevalence of abnormal cytology results was significantly lower in women aged 20-24 years who had received an HPV vaccination than in those who had not (P = 0.011). The reduction in the rate of abnormal cervical cytology results by HPV vaccination was 88.1%. CONCLUSION: Within a 4-year-5-year period following vaccination, women aged 20-24 years who received an HPV vaccination had significantly lower rates of abnormal cervical cytology results than those who did not receive the vaccine.
