Summary
This case report details a rare instance of isolated splenic metastasis originating from ascending colon cancer in a 59-year-old male. The study highlights the importance of monitoring carcinoembryonic antigen levels for early detection of colon cancer spread.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Oncology
Background:
- Primary spleen tumors are rare, with lymphoma being the most common malignancy affecting the spleen.
- Metastasis to the spleen from other organs is uncommon, particularly isolated splenic metastasis.
Observation:
- A 59-year-old male patient presented with isolated splenic metastasis from ascending colon cancer.
- The patient had undergone a right hemicolectomy for a T3N1M0 ascending colon tumor.
- Postoperative follow-up revealed elevated carcinoembryonic antigen levels and a 4 cm splenic tumor on CT scan.
Findings:
- The patient underwent a curative splenectomy for the splenic tumor.
- Pathologic examination confirmed the splenic metastasis to be adenocarcinoma originating from the colon.
- This represents the third reported case of isolated splenic metastasis from right colon carcinoma in medical literature.
Implications:
- This case underscores the possibility of isolated splenic metastasis from ascending colon cancer, even after curative surgery.
- Elevated carcinoembryonic antigen levels can serve as an important indicator for detecting such rare metastatic events.
- Further research may be warranted to understand the specific mechanisms and risk factors associated with splenic metastasis from right-sided colon cancers.
