Abstract:
Lung cancer was the most often
diagnosed cancer and the leading cause of death among men. it is usually
discovered in the late metastatic stage. Metastasis of lung cancer to
axillary lymph nodes is extremely
rare. This case report presents A
73-year-old male with a productive cough and shortness of breath
admitted to the emergency department. Physical assessment revealed
tenderness in the upper chest and lower sternal area, as well as other
symptoms. Lab results were normal, but a scan showed various lesions in
the lungs, lymph nodes, liver, and spine. A biopsy confirmed metastatic
squamous cell carcinoma originating from the lungs, and the patient
started immunotherapy. Metastasis of lung cancer to
axillary lymph nodes is rare.
Normally, lymphatic drainage to the axillary lymph nodes comes from the
upper limbs and chest wall instead of the lungs. There have been many
theories hypothesized to explain the unusual pattern of ALN metastases
from lung cancer. Lung cancers, including squamous cell carcinoma,
rarely metastasize to axillary lymph nodes, but should be considered in
cases with chest wall invasion.
