]> C08.1 Sublingual gland C08.8 Overlapping lesion of major salivary glands C08.9 Major salivary gland, NOS Note: Laterality must be coded for C08.1. &commontumorsizetongue; CS Extension Note 1: AJCC considers "in situ carcinoma of salivary gland" an impossible diagnosis. Any case so coded will be mapped to an unknown AJCC stage, in situ Summary Stage. Note 2: Periosteum is a fibrous membrane that wraps the outer surface of bones. Mucoperiosteum is a compound structure of mucous membrane and periosteum. Cortical bone is the dense compact outer layer of bone. Note 3: The assignment of T1 and T2 categories for tumors of major salivary glands without exparenchymal extension is based on tumor size. A physician's statement of the T category may be used to code 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, other than the physician's statement of the T category. Use codes 305, 310, 408, 625, 810, or 815 as appropriate to code CS Extension based on a statement of T when no other extension information is available. Note 4: Use code 300 for localized tumor only if no information is available to assign codes 100 or 305.

The complete definitions are provided in the General Rules, Section 2. Note 2: For head and neck schemas, additional information about lymph nodes (size of involved nodes, extracapsular extension, levels involved, and location of involved nodes above or below the lower border of the cricoid cartilage) is coded in CS Site-Specific Factors 1, 3-9. Note 3: If laterality of lymph nodes is not specified, assume nodes are ipsilateral. Midline nodes are considered ipsilateral. Note 4: For head and neck cancers, if lymph nodes are described only as "supraclavicular", try to determine if they are in Level IV (deep to the sternocleidomastoid muscle, in the lower jugular chain) or Level V (in the posterior triangle, inferior to the transverse cervical artery) and code appropriately. If the specific level cannot be determined, consider them as Level V nodes. Note 5: The description of lymph nodes has been standardized across the head and neck schemas. All lymph node levels and groups listed here are considered regional nodes for AJCC staging. Summary Stage 1977 and Summary Stage 2000 divide these nodes into regional and distant groups. Note 6: Mandibular nodes are included with Facial nodes.
