Malignant granular cell tumor recurred in the breast, mimicking carcinoma. Diagnosis was confirmed using electron microscopy and immunohistochemistry, highlighting the importance of identifying true metastases.

Area of Science:

  • Oncology
  • Pathology

Background:

  • Malignant granular cell tumors (MGCTs) are rare soft tissue neoplasms.
  • Chest wall MGCTs can present with aggressive behavior and metastatic potential.

Observation:

  • A case of chest wall MGCT recurred in the right breast with axillary lymph node involvement.
  • The recurrent tumor presented clinically and grossly resembling breast carcinoma.

Findings:

  • Electron microscopy and immunohistochemical techniques were crucial for accurate cytologic and histologic diagnosis.
  • Confirmation of true metastases is vital for diagnosing malignant granular cell tumor.

Implications:

  • This case underscores the importance of considering MGCT in the differential diagnosis of breast masses, especially with a history of soft tissue malignancy.
