A Huge Malignant Ovarian Tumor: A Case Report.

BACKGROUND Huge ovarian tumors are rare. In developing countries, many women with huge ovarian tumors only seek consultation when the tumor has become very large. Most cases are benign, and only a few cases were reported to be malignant. This case report presents a case of huge malignant ovarian tumor with a final diagnosis of stage III epithelial ovarian cancer. The tumor was completely removed. The huge malignant ovarian tumor in this case report was completely excisable. CASE REPORT A 43-year-old woman visited the tertiary hospital in Surabaya Indonesia in early September 2020 with a complaint of an enlarged abdomen. The patients had 3 children and normal menstrual periods. Her bowel function was normal. The patient started to notice the abdominal enlargement at 3 months prior to seeking treatment. Ultrasound examination showed a unilocular cystic mass with a diameter of >25 cm, and a solid nodule with normal vascularity was seen. No ascites was noted. Histopathologic examination showed an ovarian mass weighing 9700 g with a size of 30×28×14 cm. The final result showed that the tumor was malignant; specifically, the tumor was a sero-mucinous adenocarcinoma of the left ovary, grade II, which had metastasized to the omentum. CONCLUSIONS Huge malignant ovarian tumors tend to be at an early stage when the diagnosis is made, and they are completely excisable.
