SOX10 and epithelioid cell melanoma: SOX10 as a Diagnostic Marker for Melanoma:SOX10 staining is highly effective in identifying melanoma cells, with a 100% positivity rate in both epithelioid melanoma and melanoma with a predominantly spindle cell appearance;Given its high detection rate and strong staining intensity, SOX10 is a valuable marker for detecting melanoma cell metastasis in locations like the cerebrospinal fluid (CSF), where a large number of cells are not expected. However, a more sensitive melanoma stain should be used for confirmation, considering SOX10 is not exclusively specific for melanoma
