Summary
Intranodal myofibroblastoma, a benign tumor, can occur in lymph nodes outside the groin. This case highlights the submandibular region as a common site for this rare tumor.
Area of Science:
- Head and Neck Pathology
- Surgical Oncology
- Cytopathology
Background:
- Intranodal myofibroblastoma is a rare benign mesenchymal tumor.
- Typically found in the inguinal region, its occurrence in other lymph node sites is less documented.
Observation:
- A case of intranodal myofibroblastoma originating within a submandibular lymph node is presented.
- This represents an unusual location for this type of tumor.
Findings:
- The fine-needle aspiration cytology revealed characteristic features.
- These included benign spindle cells, pale fibrillary matrix, and hemosiderin granules.
Implications:
- This case confirms that intranodal myofibroblastomas can arise in extrainguinal locations.
- The submandibular region may be a more frequent site for this tumor than previously recognized.
- Cytologic findings are crucial for diagnosing this condition in this region.
