| anonymous | Merkel cell carcinoma (95%) Metastatic small cell carcinoma (5%) | Merkel cell carcinoma is positive for CK20 and negative for Thyroid Transcription Factor (TTF-1). | 100 |
| anonymous | Merkel cell carcinoma (100%) | Immunohistochemical study to exclude metastatic small cell carcinoma. Merkel cell carcinoma is CK20 positive. Metastatic small cell carcinomas are almost always CK20 negative. | 100 |
| anonymous | Small cell carcinoma, consistent with Merkel cell carcinoma. Need to rule out metastatic small cell carcinoma. 100% | nil | 100 |
| anonymous | Merkel cell carcinoma | Confirm by positive staining for CK20 and synaptophysin. Exclude lymphoma/leukemia by LCA negativity. | 100 |
| anonymous | Merkel cell carcinoma. 100% | nil | 100 |
| anonymous | Merkel cell carcinoma. (100%) | nil | 100 |
| anonymous | Skin - Merkel cell carcinoma (100%) | Covering skin also features verrucous hyperplasia resembling a wart. Immunostain CK20 positivity confirms the diagnosis. | 100 |
| anonymous | Merkel cell carcinoma, 100% | To be confirmed with cytokeratin 20 (CK20) immunohistochemically. Merkel cell carcinoma is CK20 positive. | 100 |
| anonymous | Merkel cell carcinoma 100% | nil | 100 |
| anonymous | Neuroendocrine carcinoma (Merkel cell carcinoma), margins involved. (100%) | Immunostaining for CK20 and neurofilament will differentiate Merkel cell carcinoma from metastatic small cell carcinoma. It is also necessary to exclude other primary sites of neuroendocrine carcinoma (small cell carcinoma), in particular the lung. | 100 |
| anonymous | Merkel cell carcinoma (100%) | nil | 100 |
| anonymous | Merkel cell carcinoma, would perform CK20, also other markers to exclude leukaemia and lymphoma. Probability: 100% | nil | 100 |
| anonymous | Merkel cell carcinoma (100%) | Confirm by immunostain for CK20. | 100 |
| anonymous | Merkel cell carcinoma | TTF1 and CK20 to exclude a metastatic small cell carcinoma and LCA to exclude lymphoma | 100 |
| anonymous | Merkel cell carcinoma | nil | 100 |
