Task: Answer Verification
Input (English): Question: Does cutaneous PEComa harbour TFE3 gene fusions : immunohistochemical and molecular study of 17 cases?
Answer: Cutaneous PEComas are mostly composed of clear cells, and, unlike a subset of visceral and deep-seated PEComas, cutaneous PEComas consistently lack TFE3 expression. Owing to the lack of SOX-10 expression, a neural crest origin could not be shown.
Output (English): no
