Primary Diffuse Large B-cell Lymphoma (DLBCL) represents the 2nd most common lymphoma occurring in the orbit, after Mucosal Associated Lymphoid Tissue (MALT) lymphoma. A total of 5 cases of ocular adnexal DLBCL were diagnosed over 25 years of experience at our tertiary eye care center. Two cases involved the lacrimal sac and one case involved the lacrimal gland. In this paper we are presenting the remaining 2 non-lacrimal cases of DLBCL. The first case is a 32 year old male who was referred with a slowly growing, painless mass involving the left medial canthal area as a case of dacryocystitis. The mass was found to be extending into the orbit inferiorly with upward displacement of the left globe. The second case is a 65 year-old lady who presented with unilateral proptosis as a result of a right orbital mass extending to the orbital apex. Histopathologic examination and immunohistochemical analysis of the incisional biopsy in both cases confirmed the diagnosis of Diffuse Large B-cell Lymphoma (DLBCL).
