Examples of retrograde lymphatic spread into ipsilateral parotid lymph nodes in 4 patients with primary tumor resection, ipsilateral or bilateral ND and in all cases ECE + ipsilateral lymph node metastases and R1 or close margin of the primary tumor (A-D). (A) SCC of the left lower alveolar ridge, pT4a pN3b ECE + close margin Pn0 LV0 G2, ND level I-III ipsilateral, recurrence type D intermediate dose. (B) SCC left buccal mucosa, pT4b pN3b ECE + R1 Pn0 LV1 G3, ND level I-III bilateral, recurrence type E. (C) SCC left maxilla, pT4a pN3b ECE + R1 Pn0 LV1 G2, ND level I-III ipsilateral, recurrence type D low dose. (D) SCC left anterior floor of mouth, pT4a pN3b ECE + R1 Pn1 LV1 G2, ND level I-III bilateral, recurrence type E. (E) Example of retrograde perineural spread along the mandibular nerve through the base of skull after resection of a SCC of the right lower alveolar ridge, pT4a pN1 ECE- R1 Pn1 LV0 G2, recurrence type D low dose. ND = neck dissection, SCC = squamous cell carcinoma, ECE = extracapsular extension
