Spindle cell hemangioendothelioma (HE) is a rare vascular tumor. This case highlights its aggressive, multifocal nature and potential for severe disfigurement despite treatment.

Area of Science:

  • Vascular Oncology
  • Dermatopathology
  • Surgical Pathology

Background:

  • Hemangioendothelioma (HE) classification evolved significantly since the 1980s.
  • Epithelioid HE identified a distinct group of vascular tumors with intermediate malignancy.
  • HEs are now classified into distinct subtypes, including spindle cell HE.

Observation:

  • A case of spindle cell HE presented as an interdigital nodule.
  • The tumor became multifocal, affecting the right upper extremity and chest wall.
  • The patient experienced severe disfigurement despite multiple surgical interventions.

Findings:

  • Spindle cell HE demonstrated aggressive, multifocal growth.
  • The tumor exhibited resistance to surgical excision.

  • The clinical course was characterized by progressive disease and significant morbidity.

    • Implications:

    • This case underscores the importance of recognizing spindle cell HE as a distinct entity.
    • Aggressive and multifocal presentations require careful management strategies.
    • Further research into the pathogenesis and treatment of spindle cell HE is warranted.
