Cervical Metastasis From Colorectal Cancer

Area of Science:

• Oncology
• Gynecologic Oncology
• Gastroenterology

Background:

• Colorectal cancer (CRC) is a common malignancy worldwide.
• Metastasis of CRC to the uterine cervix is an exceptionally rare event.
• Accurate diagnosis is essential for appropriate management of cervical masses.

Observation:

• A case of metastatic adenocarcinoma from the right colon to the uterine cervix with vaginal extension is presented.
• The metastasis occurred 3 years after the initial treatment for primary colon cancer.
• The patient presented with symptoms related to cervical and vaginal involvement.

Findings:

• Histopathological examination revealed adenocarcinoma.
• Immunohistochemical analysis was critical in determining the primary site of origin as the colon, distinguishing it from a primary cervical neoplasm.
• Specific markers confirmed the colorectal origin of the metastatic cells.

Implications:

• This case underscores the importance of considering metastatic disease in the differential diagnosis of cervical adenocarcinoma, especially in patients with a prior history of colorectal cancer.
• Immunohistochemical staining plays a pivotal role in accurate diagnosis and can significantly influence therapeutic strategies.
• Early and precise diagnosis can lead to tailored treatment plans, potentially improving patient outcomes.
