Area of Science:

  • Oncology
  • Pathology
  • Pulmonology

Background:

  • Malignant granular cell tumors (MGCTs) are exceptionally rare neoplasms.
  • Only 41 cases of MGCT have been documented globally.
  • Pulmonary involvement is exceedingly uncommon.

Purpose of the Study:

  • To report the first case of a resected primary pulmonary Malignant Granular Cell Tumor (MGCT).
  • To review the diagnostic considerations for pulmonary MGCT.
  • To discuss the differential diagnosis of granular cell tumors in the lung.

Main Methods:

  • Case presentation of a patient with primary pulmonary MGCT.
  • Review of preoperative evaluation and pathological features.
  • Histological and immunohistochemical analysis for diagnosis.

Main Results:

  • The case presented is the first documented instance of a resected primary pulmonary MGCT.
  • Diagnostic confirmation relied on histology, immunohistochemistry, and exclusion of mimics.
  • The tumor exhibited characteristic features necessitating careful pathological assessment.

Conclusions:

  • Diagnosis of MGCT requires definitive histology and immunohistochemistry.
  • Exclusion of other tumors that may resemble granular cell tumors is critical.
  • This case highlights the importance of recognizing rare pulmonary neoplasms.
