Introduction: An adnexal mass may be diagnosed after a routine pelvic ultrasonographic examination or an emergent hospital admission due to rupture of ectopic pregnancy, adnexal torsion or rupture of tuboovarian abscess. It is necessary to evaluate the origin of the mass initially and to classify patients who need further evaluation and treatment for an urgent condition. Case presentation: We report a case of sigmoid colon rupture due to sigmoid colon adenocarcinoma presenting as acute abdomen with left adnexal mass in a 28 years old woman. Abdominopelvic computed tomography revealed a left adnexal mass with suspicion of tuboovarian abscess. In laparatomy, rupture of sigmoid colon was observed and resection of sigmoid colon was performed. Histological examination of resection part revealed diagnosis of sigmoid colon adenocarcinoma due to familial adenomatous polyposis. Conclusion: This case may be interesting for clinicians because pelvic pain, fever, increased infection markers in the laboratory and mass at ultrasonography or other screening methods could cause a misdiagnosis of tubaovarian abscess especially in reproductive age women. Before the operation of the pelvic mass of all age women with the diagnosis of tuboovarian abscess other causes of the pelvic abscess should come into mine and necessary preparation for operation must be done.
