Metastatic Large Cell Neuroendocrine Carcinoma of the Lung Mimicking a Merkel Cell Carcinoma

of the lung is a newly recognized clinicopathologic entity and defined as a poorly differentiated and high-grade neuroendocrine tumor that stands morphologically and biologically between atypicall carcinoid and small cell lung carcinomal. Histopathologically, most LCNECs revealed a marked decrease in or a loss of organoid architecture and could be mistaken for poorly differentiated adenocarcino...

Neuroendocrine differentiation in primary Merkel cell carcinoma--possible prognostic significance.

BACKGROUND The aim of this study was to examine the level of neuroendocrine differentiation to determine its association with clinicopathological parameters. PATIENTS AND METHODS Twenty-five primary MCC samples were evaluated for neuroendocrine differentiation profiles by immunohistochemistry using antibodies to chromogranin-A, microtubule associated protein-2 and synaptophysin. The data were...

Digital Merkel cell carcinoma.

Merkel cell carcinoma (MCC) is a rare and biologically aggressive neuroendocrine tumour of the skin. Recent analysis of a surveillance, epidemiology and end results program has shown a statistically significant increase of 8% per year in the age-adjusted rates for MCC of the skin over the past 15 years. MCC commonly presents as a painless, rapidly growing, single red or purple cutaneous nodule....
