Bilateral Ovarian Mucinous Cystadenocarcinoma in an Adolescent Girl: A Case Report.
Primary epithelial ovarian malignancies in adolescents are extremely rare (<1%). Mucinous cystadenocarcinoma (MCAC), especially bilateral disease, is exceptional and often mimics benign ovarian cysts, delaying the diagnosis.
We report a 16-year-old girl with hypothyroidism who presented with abdominal distension, pain, and 20-kg weight gain. Imaging showed bilateral ovarian masses with omental nodularity despite normal tumor markers. Surgery confirmed FIGO IIIC bilateral MCAC, and she completed six cycles of paclitaxel-carboplatin.
At three‑ year follow‑ up, the patient continues to be disease‑ free. This case highlights the limitations of tumor markers in adolescent ovarian malignancy, emphasizes the importance of cross‑ sectional imaging and clinical correlation, and demonstrates the challenges of management including considerations of future fertility.
