This study details a rare ethmoid sinus myofibroblastoma, an uncommon mesenchymal tumor. It is the first reported case, offering insights into diagnosis and management.

Area of Science:

  • Pathology
  • Oncology
  • Otorhinolaryngology

Background:

  • Myofibroblastomas are rare mesenchymal tumors.
  • They are characterized by spindle cells with myofibroblast features.
  • Occurrence in the ethmoid sinus is exceptionally rare.

Observation:

  • A unique case of myofibroblastoma in the ethmoid sinus is presented.
  • The tumor exhibited typical myofibroblast ultrastructural and immunohistochemical characteristics.
  • Clinical presentation and diagnostic findings were documented.

Findings:

  • Histological examination confirmed the diagnosis of myofibroblastoma.
  • Immunohistochemistry supported the myofibroblastic differentiation.
  • The ethmoid sinus location is a novel finding in the literature.

Implications:

  • This case expands the known anatomical sites for myofibroblastomas.
  • It highlights the importance of considering rare diagnoses in sinonasal lesions.
  • Further understanding of ethmoid sinus myofibroblastomas may improve patient management.
