INTRODUCTION: @entity3038 in @entity1 is a very rare entity. CASE REPORT: The authors present a case of @entity3038 in a 23-month-old @entity1 . The @entity1 was admitted to our hospital with persistent @entity10 and frequent @entity391 . MR imaging demonstrated a large frontal well-circumscribed lesion with a heterogeneous @entity2287 enhancement. Although macroscopically the @entity5 was totally extirpated, the @entity1 died of rapid @entity5 regrowth 2 months after surgery. The surgical specimens obtained from the @entity5 showed an admixture of two distinctive neoplastic tissues. One was a malignant mesenchymal feature. Its fibrosarcomatous nature was characterized by spindle-shaped cells with fine fibers that were deeply stained in @entity575 preparations for reticulin. The other was gliomatous tissue forming islands surrounded by the sarcomatous tissues. Its glioblastomatous nature was obvious, as it was characterized by endothelial proliferation and perinecrotic pseudopalisading. Both tissues were histologically malignant, as evidenced by mitotic figure, high cellularity, atypical features, and variability. DISCUSSION: The literature concerning @entity5 is reviewed, and pathological and clinical features of the @entity5 are briefly discussed.
