Histopathology report

Final reports of resection specimens of tumour should include details on:

• the type of tumour present (and grade if relevant).

Figure 16.1. Resection of parotid and submandibular salivary glands. Recommended siting and orientation of blocks for resection of parotid (a) and submandibular (b) glands.

• the distance of the tumour from the nearest cutaneous/mucosal margin (if appropriate).

• the distance of the tumour from the nearest deep margin.

• the presence or absence of perineural and vascular invasion.

• the presence or absence of lymph node metastasis (if appropriate).

• TNM classification of tumour spread of salivary glands:

pT1 tumour < 2 cm, without extraparenchymal extension*. pT2 tumour <2 to < 4 cm, without extraparenchymal extension*. pT3 tumour > 4 cm, and/or extraparenchymal extension*.

pT4 tumour invades skin, mandible, ear canal, facial nerve base of skull, pterygoid plates or encases carotid artery. * Extraparenchymal extension is clinical or macroscopic evidence of invasion of soft tissues or nerve, except those listed under pT4. Microscopic evidence alone is not sufficient.

Regional lymph nodes:

pN0 no regional lymph nodes involved.

pN1 metastasis in ipsilateral single node < 3 cm diameter.

pN2 metastasis in:

a. ipsilateral single >3 to 6 cm.

b. ipsilateral multiple < 6 cm.

c. bilateral, contralateral < 6 cm.

pN3 metastasis in a lymph node > 6 cm diameter.
