Summary
Facial metastasis from colorectal cancer is exceptionally rare, with only two prior reports. This case details the first instance of malar metastasis from colon cancer, highlighting its grave prognostic implications.
Area of Science:
- Oncology
- Surgical Pathology
- Medical Imaging
Background:
- Colorectal carcinoma rarely metastasizes to the face.
- Previous literature documents only two cases of facial metastasis from colorectal cancer.
- Malar metastasis represents an extremely rare manifestation of colorectal cancer.
Observation:
- A 64-year-old woman with a history of colon cancer presented with progressive left facial edema.
- Imaging revealed a large soft tissue mass involving the zygomatic arch and masticator space.
- Biopsy confirmed metastatic adenocarcinoma, histologically consistent with the primary rectal tumor.
Findings:
- This is the first reported case of malar metastasis originating from colon carcinoma.
- The metastasis involved the zygomatic arch and surrounding facial structures.
- Histological analysis confirmed metastatic adenocarcinoma.
Implications:
- Malar metastasis from colorectal cancer is an extremely rare event.
- Its occurrence signifies advanced disease and a grave prognosis.
- Treatment is typically palliative due to widespread metastases.
