Extrapulmonary inflammatory myofibroblastic tumors (EIMTs) are rare, characterized by spindle cell proliferation. Due to frequent recurrences and potential misdiagnosis with sarcomas, EIMTs warrant careful consideration as neoplastic lesions.

Area of Science:

  • Oncology
  • Pathology
  • Surgical Pathology

Background:

  • Extrapulmonary inflammatory myofibroblastic tumor (EIMT) is a rare entity.
  • EIMTs are characterized by the proliferation of spindle cells with a myofibroblast phenotype.
  • Distinguishing EIMTs from other soft tissue lesions can be challenging.

Observation:

  • The authors describe literature data and three personally observed cases of EIMT.
  • Observed cases presented with characteristic spindle cell proliferation.
  • Morphological similarities between EIMT and soft tissue sarcomas were noted.

Findings:

  • EIMTs exhibit frequent recurrences, suggesting neoplastic behavior.
  • The prognosis for EIMT is often indefinite, necessitating tumor-like classification.

  • Hyperdiagnosis of malignancy is a potential pitfall due to morphological overlap with sarcomas.

    • Implications:

    • Accurate diagnosis of EIMT is crucial to avoid misclassification as benign or malignant.
    • Understanding the neoplastic potential of EIMT informs treatment strategies.
    • Awareness of morphological similarities aids in differentiating EIMT from soft tissue sarcomas.
