Abstract

Gastrointestinal Stromal Tumors (GIST) are a rare heterogeneous group of non-epithelial neoplasms which originate from gastrointestinal mesenchymal tissue. Very rarely, these tumors arise from extraintestinal site. In these cases they are defined as Extragastrointestinal Stromal Tumors’ (EGISTs). The most common sites are the omentum, the mesentery and the etroperitoneum.
EGISTs represent 1% of all GIST.
We report a rare case of a recurrent EGIST of the Rectovaginal Septum (RVS) considering that identification, incidence, tumor behavior, and surgical treatment is still debated.
In July 2004 a 43-year-old woman underwent local excision for EGIST of RVS in another hospital. Adjuvant Treatment (AT) with Imatinib and a follow-up every 4 months was scheduled. In February 2011 Local Recurrence (LR) occurred. Low anterior resection of the rectum extended to the lesion was undergone. Imatinib was resumed with closed follow-up. In April 2017 a second LR of the
vaginal canal occurred. A new pharmacological trial based on Sunitinib and Masitinib was started. In June 2018 by CT scan and pelvic-MRI, a third LR closed with the neo-rectum and the vagina’s distal portion was identified. Clinically the patient presented a voluminous and painful mass of the perineal region and Rectovaginal Fistula (RF) with loss of stool. By the Multidisciplinary Team
(MDT) meetings debulking surgery was planned and performed through a multivisceral resection of the LR by three Surgical Teams (ST) with a combined abdominal-perineal approach. MDT and specialized ST are mandatory in the management of these rare tumors that must be provided in cancer center.
