Male breast cancer comprises of 1% of all and invasive lobular carcinomas (ILC) are even rarer in males. ILC are known to have unusual metastatic sites. We report a case of a 51-year-old male diagnosed with breast cancer, who presented with a recurrent chest wall nodule and icterus after 24 months of disease-free interval. On further investigations, he was found to have pancreatic head mass associated with conjugated hyperbilirubinemia suggestive of obstructive jaundice and a left parasternal soft tissue recurrence. A self-expandable metallic stent was inserted for recurrent cholangitis. Biopsy from the chest wall nodule was recurrence of ILC and pancreatic head mass was suspected to be either a second primary or an isolated pancreatic head metastasis of ILC on imaging. In either case surgical resection if operable and localized was planned. However, on staging laparoscopy, the patient was found to have mild ascites and multiple peritoneal nodules, which on biopsy proved to be metastases from ILC. Patient was treated with second-line hormonal therapy with luteinizing hormone-releasing hormone agonist and an aromatase inhibitor. ILC may present with unusual sites of metastasis leading to diagnostic dilemma. A high index of suspicion of metastases and appropriate biopsies can help one embark upon the most appropriate plan.
