Final Diagnosis -- Right Cheek Mass (Squamous Cell Carcinoma)
- FINAL DIAGNOSIS:
- PART 1: TISSUE FROM RIGHT DEEP NECK, BIOPSY -
- Dense fibroconnective tissue with foreign body (suture) granulomas.
- PART 2: LYMPH NODE, RIGHT POSTERIOR TRIANGLE, BIOPSY -
- Benign lymph node.
- PART 3: RIGHT NECK MASS AND HEMIMANDIBLE, HEMIMANDIBULECTOMY -
- A. Recurrent well to moderately differentiated
squamous cell carcinoma involving perimandibular
soft tissues and skin with direct extension into
periosteum of mandibular bone (section 3F).
- B. History of previously resected squamous cell
carcinoma of the right buccal mucosa.
- C. No perineural invasion seen.
- D. All soft tissue and bony resection margins free of tumor.
The exact nature of this tumor is difficult to discern. The previous biopsy specimen is from the buccal mucosa, but shows tumor also surrounding the right submandibular gland. The current specimen is from the skin of the right cheek/submandible and most likely represents direct extension of the primary tumor to the region of the submandibular gland. The periosteal invasion seen is at the region of a previous tooth extraction.
