]> C69.6 Orbit, NOS Note 1: Laterality must be coded for this site. Note 2: AJCC uses this scheme only for sarcomas of the orbit. &commontumorsizeorbit; CS Extension Note 1: The orbital tissues are the support systems of the globe, confined to the space within the surrounding bony structure. The tissues include fat, striated and smooth muscle, and fibroconnective, vascular, lymphoid, peripheral nerve, and optic nerve tissue. Note 2: AJCC stages only sarcomas of the orbit. AJCC values are derived as NA for all non-sarcoma histologies coded to this site. Note 3: Code 000 may be used only for non-sarcoma histologies coded to this site. Sarcomas do not present as in situ or noninvasive tumors.
