Recurrent Invasive Adenocarcinoma after Hysterectomy for Cervical Adenocarcinoma in Situ

Abstract

Background. Unlike its squamous counterpart, therapy for cervical adenocarcinoma in situ with positive endocervical cone margin remains controversial.Case. A 52-year-old gravida 2, para 1,0,1,1, presented with vaginal bleeding. Gynecologic history was significant for cervical cold knife conization with a positive endocervical margin and endocervical curettage with atypical endocervical cells. Repeat cone biopsy was considered unsafe given the large initial cone specimen. An extrafascial hysterectomy was performed 5 weeks later and pathology confirmed a disease-free cervix. Pap smear performed 1 year later was interpreted as recurrent adenocarcinoma but later downgraded to inflammation. Inspection and random biopsies of the vaginal cuff revealed only inflammation. Two subsequent Pap smears also returned inflammation. Seventeen months after the hysterectomy physical examination revealed a 2 × 3-cm smooth mass at the vaginal cuff. Biopsy revealed invasive adenocarcinoma. The patient underwent an upper vaginectomy followed by postoperative pelvic radiation.Conclusion. This case suggests that despite extrafascial hysterectomy for presumed adenocarcinoma in situ of the cervix, a residual focus could remain and present later as invasive adenocarcinoma.
