The thyroid gland is a rare site for cancer metastasis. We report a 75-year-old man who was referred with a history of hematuria and generalized bone pain for the past few months. He had a past history of partial left lobe thyroidectomy for follicular adenoma. Subsequently he was referred for a thyroid mass and a subtotal thyroidectomy showed a poorly-differentiated carcinoma. On the latest admission, the patient underwent resection of a bladder tumour with malignant histology and an immunohistochemical profile of CK7+/CK20+/34 Beta E12+/CEA-/PSA-. Re-examination of thyroid sections with immunohistochemical stains revealed the malignant cells to be CK7+/CK20+/34 Beta E12+/CEA-/TTF1-. The findings were compatible with metastasis of the bladder transitional cell carcinoma to the thyroid gland.Scans revealed multiple liver and bone metastases. The patient died 2 months after the diagnosis.

Concurrent laryngeal squamous cell carcinoma and intrahepatic cholangiocarcinoma is rare and no prior report has been found through a PubMed search. Here we report such a case of a 51-year old obese male presenting with hoarseness and trouble swallowing for 2 to 3 months. Imaging findings of computer tomography (CT) and magnetic resonance imaging (MRI) with and without contrast were suspicious for a T3N2 supraglottic laryngeal cancer. Laryngeal biopsy showed a well differentiated squamous cell carcinoma (SCC). As part of the evaluation of the laryngeal SCC, MRI abdomen showed an enhancing mass (4.6 cm in the greatest dimension) with diffusion restriction and capsular retraction in the right lobe of the liver. Ultrasound-guided percutaneous biopsy of the liver revealed a moderately differentiated adenocarcinoma, that was strongly and diffusely positive for CK7 and CK19, weakly positive for CDX2, and negative for HepPar 1, glypican 3, CK20, PSA and TTF1. The immunohistochemistry profile was consistent with cholangiocarcinoma. This is a unique case of laryngeal squamous cell carcinoma with concurrent cholangiocarcinoma. The prognosis was poor and the patient was placed in hospice care in two months after the diagnoses. To the best of our knowledge, this is the first documented case of synchronous laryngeal squamous cell carcinoma and intrahepatic cholangiocarcinoma. The pathogenesis, diagnosis and treatment of the diseases are discussed.
