Malignant mixed epithelial tumour of ovary-serous papillary cystadenocarcinoma and transitional cell carcinoma with tubo-ovarian torsion: a rare tumour with rare presentation.

ABSTRACT

Ovarian torsion can be associated with various pathophysiological factors. Most commonly, benign epithelial ovarian tumours present with torsion. We present an unusual case of mixed malignant epithelial ovarian tumour with a predominant component of high-grade serous cystadenocarcinoma (85%) and transitional cell carcinoma (TCC) (15%) in a patient who presented with acute lower abdomen. The tumour was associated with tubo-ovarian torsion.
