For example, disease entities that resemble well-differentiated neuroendocrine tumors, such as pseudoendocrine sarcoma, mesenchymal neoplasms with GLI1 gene alterations described as “distinctive nested glomoid neoplasm,” gastroblastoma, and plexiform fibromyxoma have been reported (1–7). The gene discussed is GLI1; the disease is mesenchymal cell neoplasm.
