Abstract

We describe an extremely rare case of advanced pure primary ovarian squamous cell carcinoma (SCC), treated by adjuvant chemotherapy with dose-dense paclitaxel combined with carboplatin (dd-TC) plus the combination chemotherapy with irinotecan and cisplatin (CPT-P), with long-term recurrence-free survival. A 71-year-old woman complaining of lower abdominal pain was referred to our hospital and a 7-cm-diameter solid tumor was identified. She was diagnosed with a left ovarian tumor that was highly suspicious for malignancy based on ultrasonography, magnetic resonance imaging, and contrast-enhanced computed tomography. Bilateral salpingo-oophorectomy, low-anterior colon resection, and colostomy were performed. Intra- and post-operative histopathological diagnosis revealed International Federation of Gynecology and Obstetrics stage IIIc well-differentiated pure ovarian SCC. As adjuvant chemotherapy, 2 courses of dd-TC were administered, followed by 3 courses of CPT-P; the patient then underwent 4 additional courses of dd-TC. Both regimens were effective and there has been no recurrence or metastasis thus far in the 5 years since the operation.

Figure

  • Fig. 1 Magnetic resonance (A-C) and contrast-enhanced computed tomography (D) images revealed a solid tumor of the left ovary, 70×50 mm in diameter. Malignancy and adhesion to the adjacent intestine were highly suspected.

  • Fig. 2 Macroscopic findings of the left ovary (A) and sigmoid colon (B). Squamous cell carcinoma (SCC) directly invaded the submucosal layer of the sigmoid colon (C). Histopathologic findings of the left ovarian tumor (D, E) (objective magnification ×4 and ×20) revealed well-differentiated pure ovarian SCC.
