Extragastrointestinal tumour of rectovaginal septum (rvGIST) is a rare malignancy that affects rectovaginal septum.
We present a case of rvGIST that was initially managed as cervical eGIST based on clinical assessment. A 66-yearold woman presented with postmenopausal bleeding and constipation. Bimanual pelvic examination revealed an
irregular mass occupying the vagina. CT thorax, abdomen and pelvis showed a 9.2 x 10.0 x 14.0 cm pelvic mass
arising from cervix, extending superiorly to involve the uterus. The patient proceeded to undergo total abdominal
hysterectomy, bilateral salpingo-oophorectomy, enucleation of rectovaginal septum mass, rectosigmoidectomy and
permanent colostomy. Intraoperatively, there was a 9 x 7 cm mass arising from rectovaginal septum. Histopathological examination of surgical specimen revealed spindle cell tumour diffusely positive for CD34, CD117 and DOG1.
The final diagnosis was rvGIST. In conclusion, the diagnosis of rvGIST require a combination of clinical assessment
with intraoperative finding and histological assessment of the surgical specimen.
