Among the 191 genes demonstrating significant differential expression between prognostic groups, keratin 20 and neurofilament protein have previously been identified in studies of MCC and were significantly upregulated in tumors from patients with a poor prognosis.
To establish the identity of the tumor and further characterize the tumor cells, staining with a broad panel of immunohistochemical stains (pankeratin, synaptophysin, chromogranin, CD56, neuron-specific enolase, smooth muscle actin, desmin, CD117 [c-KlT], CD34, S100, human melanoma black-45 [HMB-45], melanocyte differentiation antigen [Melan-A], microphthalmia-associated transcription factor [MiTF], TFE3, neurofilament protein, glial fibrillary acidic protein, estrogen receptor, and progesterone receptor) and electron microscopy were performed.
The tumor cells were strong diffusely immunostained with both neuron-specific enolase and neurofilament protein and partially for synaptophysin.
