A Case of Lung Cancer with Isolated Skip Metastasis to an External Iliac Lymph Node

Deanna Ng, Grace Tan, Angela Takano, Melissa Teo


Introduction: Isolated skip metastases to intra-abdominal lymph nodes from lung cancer are rare and management of such disease remains controversial. 

Presentation of case: We report a case of lung adenocarcinoma in the right upper lobe with isolated lymph node metastasis to an external iliac lymph node detected by Positron Emission Tomography (PET) scan which was confirmed histopathologically.  Conclusion: Isolated intra-abdominal lymph nodes from lung cancer are a rare occurrence.  In these patients, lymphadenectomy can be considered together with definitive treatment of the lung primary.
