First case of intracaval recurrence of high‐grade endometrial stromal sarcoma: A case report
Abstract
Intravascular tumor thrombus (ITT) is a dangerous condition defined as tumor extension into a blood vessel. Endometrial stroma sarcomas (ESS) rarely involve the great vessels [1]. ESS are rare, indolent tumors that account for 25% of uterine sarcomas [2], and they are usually classified as low-grade (LG) or high-grade (HG) [3]. Whilst 29 LG-ESS cases of ITT have been described in the literature since 1986 (Table 1), no cases of ITT from HG-ESS have been reported yet. The present study reports the case of a 57-year-old patient with a recurrence of HG-ESS. Five years before presenting at our institution, the patient underwent total abdominal hysterectomy with bilateral adnexectomy and systematic pelvic lymphadenectomy, followed by chemo-radiotherapy for HG-ESS (FIGO stage III C) [4]. During routine follow-up, a computed tomography (CT) scan diagnosed a recurrence of HG-ESS at the para-caval lymph nodes.
