What Researchers Did
Researchers presented the case of a 55-year-old woman with intraosseous adenoid cystic carcinoma (ACC) in the mandible that later developed multiple distant metastases.
What They Found
Three years after initial treatment, the patient developed multiple lung metastases, followed by new metastatic lesions in the pancreas, mammary gland, and kidney five years post-resection. This case uniquely describes the manifestation of intraosseous ACC metastases in the breast and kidney, with the mammary gland metastasis staining positive for epithelial growth factor receptor.
What This Means for Canadian Patients
Canadian patients with adenoid cystic carcinoma should be aware of the potential for distant metastases, even years after initial treatment. This case highlights the importance of long-term follow-up and considering unusual sites for recurrence in ACC.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
As a case report, the findings are limited to a single patient and cannot be generalized to a broader population.
