Axillary nodal metastasis of operated gallbladder carcinoma: remote site of aggression—a case report

Abstract

Abstract Background Gallbladder cancer is a very aggressive type of biliary tract cancer. The only curative treatment is complete surgical excision of the tumour. However, even after surgery, there is still a risk of recurrence of the cancer. Case presentation A 63-year-old gentleman presented with the complaint of a non-healing ulcer at upper abdomen for the last 1 month. He had undergone a laparoscopic cholecystectomy at a private centre 4 months ago. Investigations confirmed the diagnosis of epigastric port site metastasis from a primary from gall bladder adenocarcinoma. After undergoing completion radical cholecystectomy with wide local excision of the epigastric ulcer, he received 6 cycles of concurrent chemoradiotherapy. Eighteen months later, he presented to us with bilateral axillary swellings. Investigations confirmed isolated bilateral axillary metastasis and the patient underwent a bilateral axillary lymphadenectomy (Level 3). However, PET scan after 6 months showed widespread metastasis and the patient succumbed to the illness 1 month later. Conclusion Axillary metastasis probably occurs due to the presence of microscopic systemic metastasis at the time of development of port site metastasis. An R0 resection of the malignancy is the only viable option for effective therapy. The present case highlights the rare involvement of isolated bilateral axillary lymph nodes as a distant metastatic site with no evidence of disease in the locoregional site. However, the prognosis after metastasis remains dismal despite multiple treatment modalities.
