假肉瘤性筋膜炎(PseudosareomatousFas(?)itis)或结节性筋膜炎(Nodular Fasc-iitis),为发生于软组织的一种原因不甚明确的瘤样病变,具有一定的临床及病理特征,常易误诊为软组织的肉瘤。我科自1974年至今共有30例,报告如下。资料与方法复查该期间诊断为假肉瘤性筋膜炎的全部病理切片,剔除3例原诊断为假肉瘤性筋膜炎而实属真皮纤维组织细胞瘤。对符合诊断的30例病史进行复查,并对部分病例重新切片作VG、网收纤维、AB/PAS染色。 Pseudosareomatous Fas (?)itis or Nodular Fasc-iitis is a type of neoplastic lesion that occurs in soft tissue and is not well defined. It has certain clinical and pathological features. Often misdiagnosed as a soft tissue sarcoma. A total of 30 cases of our department since 1974 have been reported as follows. Materials and methods All pathological sections diagnosed as pseudosarcomatous fasciitis during the period were reviewed, and 3 cases of pseudosarcomatous fasciitis originally diagnosed were actually dermal fibrous histocytomas. A review of the history of the 30 patients who were eligible for the diagnosis was performed and some of the cases were re-sectioned for VG, fibrosis, and AB/PAS staining.
