Summary
Melanoma metastasis rarely occurs in the colon and is hard to diagnose. This case highlights how it can appear as a non-pigmented polyp during endoscopy.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Colonic metastases from melanoma are uncommon.
- Diagnosis of these metastases is challenging due to asymptomatic presentation.
- Metastatic melanoma can manifest endoscopically as a non-pigmented polyp.
Observation:
- A 56-year-old woman presented with an unusual-looking polyp during colonoscopy.
- The polyp was removed via polypectomy for further examination.
Findings:
- Histopathological analysis confirmed the polyp to be a metastasis of melanoma.
- This case demonstrates a rare presentation of metastatic melanoma in the colon.
Implications:
- Highlights the importance of considering metastatic melanoma in the differential diagnosis of colonic polyps, even if non-pigmented.
- Emphasizes the role of endoscopic polypectomy in diagnosing rare gastrointestinal malignancies.
- Suggests the need for increased awareness among clinicians regarding unusual endoscopic findings potentially representing metastatic disease.
