| Popis: | Highlights • We present a rare case of abdominal sarcomatosis from uterine leiomyosarcoma. • The patient underwent myomectomy for occult STUMP 3 years before. • Risk of relapse, dissemination and malignant transformation of STUMP is uncertain. • STUMPs require a close surveillance especially after conservative surgery. • Laparoscopy may allow timely diagnosis and treatment of STUMP recurrence. Introduction Although rare, cases of abdominal sarcomatosis (AS) after laparotomy/laparoscopic interventions for uterine smooth muscle tumors of uncertain malignant potential (STUMP) have been reported. Presentation of case We describe a rare case of diffuse abdominal sarcomatosis in a patient that some year earlier had undergone myomectomy for a suspected uterine myoma, which was histologically proven to be a STUMP. Once the patient was admitted at our Department, she underwent a diagnostic laparoscopy that confirmed a condition of peritoneal sarcomatosis disseminated through the entire abdomen, and then a laparotomic total hysterectomy, bilateral salpingo-oophorectomy, and total omentectomy, achieving a complete cytoreduction. Histological examination showed high-grade uterine leyomiosarcoma (LMS). Since there is no evidence of any clinical benefit of adjuvant treatment, given the risk of disease recurrence, we decided, with the patient’s agreement, to conduct close follow-up with a Positron Emission Tomography (PET)/Computed Tomography (CT) scan every 3 months and diagnostic laparoscopy every 6 months, even in the absence of PET/CT positivity. After 2 years PET/CT showed a relapse of LMS in the perigastric region and, therefore the patient underwent a diagnostic/operative laparoscopy with complete removal of the neoplastic recurrence. To date, the patient is disease-free. Discussion and conclusion STUMPs should be submitted to a frequent surveillance for their risk of recurrence, dissemination and transformation into LMS, even many years after the first diagnosis. A follow-up including surgical re-exploration with laparoscopy and PET/CT imaging may allow early detection and timely treatment of the relapse with good long-term outcome, as demonstrated by our case. |
