Summary
Sister Mary Joseph's nodules are rare umbilical metastases, typically from abdominal cancers. This case report details the first known instance of lymphoma presenting as an umbilical nodule, challenging historical observations.
Area of Science:
- Oncology
- Pathology
Background:
- Metastatic tumors to the umbilicus, known as Sister Mary Joseph's nodules, are uncommon.
- These metastases are usually associated with intra-abdominal adenocarcinomas.
- Lymphomas have historically not been reported as a cause of umbilical metastases.
Observation:
- This case report describes a patient with lymphoma presenting as an umbilical nodule.
- The umbilical nodule was the initial presentation of the lymphoma.
Findings:
- This represents the first documented case of lymphoma manifesting as an umbilical nodule.
- This finding expands the known differential diagnosis for Sister Mary Joseph's nodules.
Implications:
- The umbilicus can be a site for lymphoma metastasis, contrary to previous understanding.
- Clinicians should consider lymphoma in the differential diagnosis of umbilical nodules, even in the absence of typical intra-abdominal malignancy.
- This case highlights the importance of thorough diagnostic evaluation for unusual presentations of cancer.
