摘要

横纹肌肉瘤是一类异质性恶性软组织肿瘤，其特点是横纹肌分化不成熟。上皮样和纺锤形细胞横纹肌肉瘤是最近才被描述的一种实体瘤，主要发生在骨内，且主要见于年轻患者。这种肿瘤诊断较晚，且具有高度侵袭性，预后较差，因此强调早期识别和适当治疗的重要性。我们在此通过一例误导性病例，从临床、组织病理学、免疫组化和分子学等方面介绍了这种肿瘤。

[Of muscle and bone: Diagnostic challenge of an uncommonly located rhabdomyosarcoma].

Rhabdomyosarcomas form a heterogeneous group of malignant soft tissue tumors characterized by immature striated muscle differentiation. Epithelioid and spindle cell rhabdomyosarcoma is a recently described entity, mainly localized intraosseously and predominantly found in young patients. Its late diagnosis and high aggressiveness confer a grim prognosis to this tumor, highlighting the importance of early recognition and appropriate management. We present herein the clinical, histopathological, immunohistochemical, and molecular aspects of this entity through a case of misleading presentation.
