]> M-8720-8790 C69.0 Conjunctiva Note: Laterality must be coded for this site. &generalsize; CS Extension Note 1: The substantia propria is the stromal tissue of the conjunctiva underlying the epithelium. The bulbar conjunctiva covers the eyeball, the palpebral conjunctiva lines the eyelids, and the forniceal conjunctiva covers the junction of the eyelid and eyeball. The caruncle is the fleshy prominence at the inner corner of the eye lined by conjunctival epithelium. Note 2: Tumors confined to the epithelium are staged as Tis in AJCC 7th Edition. Unless corneal extension is present, they are staged as T1 in AJCC 6th Edition. Note 3: Quadrants of involvement are coded in CS Site-Specific Factor 2.

This is not the same as the histologic grade defined in the ICD-O, designating degrees of differentiation from normal tissue such as "well differentiated" or "poorly differentiated", which is coded in the traditional grade field. Note 2: Tumors of Grade 0, Primary acquired melanosis without cellular atypia, and Grade 1, Conjunctival nevus, are not reportable to the cancer registry. Tumors of Grade 2, Primary acquired melanosis with cellular atypia (epithelial disease only) are reportable and may be coded as 8741/2. Note 3: Code this field only from a statement of grade describing PAM with atypia or de novo melanoma, documented by the managing physician or the pathologist in the record. Do not interpret or attempt to assign grade based on the histologic diagnosis of the tumor.
