Core Tip

Core Tip: Tumor-to-tumor metastasis is an unusual occurrence. We present a case in which tumor metastasis has been observed, stemming from colorectal adenocarcinoma to a mature ovarian teratoma. This serves as a reminder for clinicians to remain vigilant. While mature ovarian teratomas are typically benign, it is essential to contemplate resection when a patient presents with concurrent colorectal adenocarcinoma. This is due to the potential risk of tumor-to-tumor metastasis.
