[57] are now understood as ultrastructural variants of GIST [60], based on their histologic and immunohistochemical simi-larity with GISTs, KIT-positivity and occurrence of GIST-spe-cific KIT-mutations. [ 7 ] reported that several benign tumors, including a leiomyoma of the uterus, took up enough 18 F-FDG to produce false-positive results for melanoma. We try to investigate potential immunohistochemical parameters that could be essential to distinguish cases of malignant smooth muscle tumors and those of uncertain or borderline histology.
