Necrotizing granulomatous inflammation in an ipsilateral axillary lymph node in a patient with invasive ductal carcinoma of the breast.

A patient presented with flu-like symptoms and a warm, tender area in the left axilla after working with an ancient piece of Cyprus wood. Antibiotics prescribed failed to improve symptoms. Followup physical examination and subsequent ultrasound found suspicious left-breast mass and an enlarged lymph node in the left axilla. Biopsy and lumpectomy of the left-breast mass revealed invasive ductal carcinoma. Biopsy and excision of the enlarged lymph node in the left axilla revealed necrotizing granulomatous inflammation without evidence of metastatic breast carcinoma. To our knowledge, this is the first case report to show the coexistence of breast cancer with necrotizing granulomatous inflammation in the ipsilateral axillary lymph node, likely due to exposure to ancient wood.
