Background: Midline nodal cancer of unknown primary (CUP) has varying definitions and an unclear natural history compared to that of extragonadal germ cell cancer (EGCC) and neuroendocrine tumors. Methods: We systematically ...

Cancer of unknown primary (CUP) is a common, well-recognized and heterogeneous clinical syndrome. Patients with CUP present with metastatic disease in the absence of an identifiable primary tumour despite a diagnostic ...

Merkel cell nodal carcinoma of unknown primary (MCCUP) is a rare neuroendocrine tumour with distinct clinical and biological behaviour. We conducted a review of retrospective data extracted from 90 patients focusing on the ...

Neuroendocrine carcinomas of the bladder (small cell, large cell, typical and atypical carcinoids) are rare and usually co exist with urothelial carcinoma. As in small cell carcinoma of the lung, various paraneoplastic ...
