In this case study, we present a 30-year-old nulliparous female with subfertility complaints and irregular menstrual cycles, who was initially misdiagnosed with an ovarian cyst. Subsequent comprehensive imaging, including Color Doppler, revealed high vascularity, and prompting suspicion of malignancy. Surgical resection and histopathological evaluation ultimately confirmed the presence of a rare Carcinoid tumor, insular type. This case emphasizes a multidisciplinary approach to the early detection and accurate diagnosis of POCs.
