Late stage tumors may present with signs of orbital invasion, such as proptosis and nonaxial globe displacement, lymphadenopathy, overlying skin ulceration, and rarely, distant metastasis. Pathology Inflammatory. T stage was retroactively determined where possible using extent of disease and collaborative stage staging codes for tumor size and location following the classification protocol determined by the American Joint Committee on Cancer; tumors were defined as T1 for size less than 2 cm with no extraglandular extension, T2 for size between 2 and 4 cm with no extraglandular extension, T3 for size … 9 In 227 of 260 patients (87%) the lacrimal gland lymphoma was unilateral, whereas 33 patients (13%) had bilateral lacrimal gland involvement .
