ESR >19.5 mm/1/2 h and CRP >11.5 mg/L were the best predictors of TOA. The high level of CRP and ESR was associated with longer duration of hospitalization and disease severity, and these levels were statistically significantly associated with TOA size of ≥5 cm.

HighlightsAppendiceal tumors are rare, late-diagnosed neoplasms that may not be differentiated from adnexal masses.Pre-operative diagnosis remains difficult and it can be mimicking adnexal mass.It may be asymptomatic and remain undiagnosed until surgery.Appendiceal tumor kept in mind in a patient with diagnosed adnexal mass, especially patient had a non-specific clinical symptoms, laboratory and radiologic findings.

Although limited by small sample size and retrospective nature, age under 50 years, stage of disease, and adjuvant chemotherapy are significant prognostic factors for survival for uterine sarcomas.

Adnexal masses are formations seen in women of all ages; they most often include cystic elements. Medical history, physical examination, different imaging methods, and tumor marker determinations must be used together for preoperative evaluation of an adnexal mass. Both benign and malignant tumors of the small intestine are more rarely encountered than malignant tumors of other gastrointestinal system components; although advanced imaging methods and other diagnostic techniques are used, they do not always allow these tumors to be differentiated from adnexal masses. We report here on two cases operated on with the preliminary diagnosis of an adnexal mass, in which the presence of a gastrointestinal stromal tumor and a leiomyoma of the ileum, respectively, was established.
