Area of Science:

  • Pulmonology
  • Oncology
  • Pathology

Background:

  • Pulmonary hemangiopericytoma is a rare tumor originating from pericytes.
  • Malignant variants are exceptionally uncommon, posing diagnostic and therapeutic challenges.

Observation:

  • A 45-year-old woman presented with chronic cough and exertional dyspnea.
  • Imaging revealed a primary pulmonary mass, diagnosed as malignant hemangiopericytoma.

Findings:

  • The patient underwent surgical resection of the primary tumor.
  • A metastatic lesion in the contralateral lung was identified and removed one year post-resection.

Implications:

  • This case underscores the potential for late metastasis in malignant pulmonary hemangiopericytoma.
