AJCC 7th Edition includes a T3 category for head and neck skin primaries only. Note 2: In the case of multiple simultaneous tumors, code the tumor with the greatest extension. Note 3: Skin ulceration does not alter the AJCC T category. Note 4: The assignment of the T1 category for cutaneous squamous cell carcinomas with one or no high-risk features is based on tumor size. A physician's statement of the T1 category may be used to code both CS Tumor Size and/or CS Extension if this is the only information in the medical record regarding one or both of these fields. However the two fields are coded independently; for example, the record may document size but not extension. Use codes 510, 520, 600, and 810 as appropriate to code CS Extension based on a statement of T when no other extension information is available. Note 5: Use code 400 (Localized, NOS) when no further information is available to assign code 100, 500, 510, or 520.

Distant nodes are coded in CS Mets at DX. Note 2: Bilateral or contralateral nodes are considered regional nodes for head, neck, and truncal tumors with bidirectional drainage to primary nodal basins, as shown on lymphoscintigraphy. Truncal tumors may also drain to both cephalad and caudal primary nodal basins as shown on lymphoscintigraphy. Clinical assessment of bilateral/contralateral or cephalad/caudal regional nodal involvement is required for tumors where lymphoscintigraphy is not performed. Note 3: Contiguous or secondary nodal basins are the next nodal drainage basins beyond the primary nodal basins. Secondary basins are considered regional for AJCC staging but may be distant for Summary Stage. Use code 270 for involvement of nodes in secondary nodal basins not specified in codes 150 and 160.
