Summary
Sentinel lymph node biopsy for breast cancer can reveal unusual lymphatic drainage patterns. Accurate nodal staging requires careful examination of all potential sites, including unexpected locations like Level III axilla.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Accurate nodal staging is crucial for breast cancer treatment.
- Sentinel lymph node biopsy (SLNB) is standard for staging.
- Anomalous lymphatic drainage can complicate SLNB.
Purpose of the Study:
- To report a case of unexpected sentinel lymph node location.
- To highlight the importance of thorough nodal basin examination in breast cancer staging.
Main Methods:
- A case presentation of a 40-year-old female with ductal carcinoma in-situ (DCIS).
- Preoperative lymphoscintigraphy and intraoperative isosulfan blue dye injection.
- Sentinel lymph node biopsy with identification of nodes in Level I and Level III axilla.
Main Results:
- Two sentinel lymph nodes were identified and biopsied.
- One sentinel lymph node was found in an anomalous location (Level III axilla).
- Both sentinel lymph nodes were negative for metastasis.
Conclusions:
- Sentinel lymph node biopsy can identify unexpected lymphatic drainage patterns.
- Comprehensive preoperative imaging and intraoperative assessment are vital for accurate nodal staging.
- Meticulous examination of all nodal basins is essential to avoid understaging breast cancer.
