Overview
Laboratory findings consistent with the diagnosis of merkel cell cancer include immunohistochemistry, cytogenetic and molecular analysis, and lymph node biopsy. .
Laboratory findings
Laboratory findings consistent with the diagnosis of merkel cell cancer include:
Lymph Node Biopsy
- Sentinel lymph node biopsy is the gold standard test for the diagnosis of merkel cell cancer.[1][2][3][4][5]
- Sentinel lymph node biopsy plays a crucial role in:
Immunohistochemistry
- Epithelial markers play an important role in the diagnosis of merkel cell cancer which include:[6][7]
- Cytokeratin AE1/AE3
- CAM 5.2
- Pan-cytokeratin
- Epithelial membrane antigen
- Ber-EP4
- Merkel cell carcinoma may also shows positive for neuroendocrine markers such as:[8][9]
- Chromogranin
- Synaptophysin
- Calcitonin
- Vasoactive intestinal peptide
- Somatostatin receptors (SSTRs)
Cytogenetic and molecular analysis
- Many chromosomal abnormalities have been detected in merkel cell cancer but most commonly affected are:[10][11][12][13]
- Chromosome 1: Especially involving p and q arms
- Chromosome 5
- Chromosome 6
- Chromosome 8
- Chromosome 13
