]> C69.5 Lacrimal sac, lacrimal duct Note 1: CS Site-Specific Factor 25 is used to discriminate between lacrimal gland, staged by AJCC, and lacrimal sac, not staged by AJCC. Both sites are coded to ICD-O-3 code C69.5. Note 2: Laterality must be coded for this site. CS Tumor Size Code Description 000 No mass/tumor found 001-988 989 989 mm or larger 990 Microscopic focus or foci only and no size of focus given 991 Described as "less than 1 centimeter (cm)" 992 Described as "less than 2 cm," or "greater than 1 cm," or "between 1 cm and 2 cm" 993 Described as "less than 3 cm," or "greater than 2 cm," or "between 2 cm and 3 cm" 994 Described as "less than 4 cm," or "greater than 3 cm," or "between 3 cm and 4 cm" 995 Described as "less than 5 cm," or "greater than 4 cm," or "between 4 cm and 5 cm" 996 Described as "greater than 5 cm" 999 CS Extension Note 1: The lacrimal sac is the upper dilated end of the nasolacrimal duct, lodged in a deep groove formed by the lacrimal bone and frontal process of the maxilla. The sac connects the lacrimal canaliculi, which drain tears from the eye's surface, and the nasolacrimal duct, which conveys this fluid into the nasal cavity. The most common epithelial tumors of the lacrimal sac are squamous cell and transitional cell carcinomas. Note 2: Periosteum is a fibrous membrane that wraps the outer surface of bones. Note 3: AJCC excludes lacrimal sac tumors from 7th Edition staging for the lacrimal gland. Lacrimal sac tumors were not explicitly excluded from AJCC 6th Edition staging. Note 4: AJCC considers "in situ carcinoma of lacrimal gland" an impossible diagnosis. Cases with extension code 000 are mapped to TX in AJCC staging. Cases with extension code 000 are mapped to in situ in Summary Stage.
