Typically patients are between 50 and 70 years of age, with no recognized gender predilection 6. Clinical presentation Clinical presentation is variable as any part of the orbit can be involved. Pathology Orbital lymphoma is a B-cell non-Hodgkin lymphoma , and in most cases arises from mucosa-associated lymphoid tissue i. It is unclear, however, if MALT exists normally in the conjunctiva of the eye, or whether it represents a sequela of inflammation thus the potential link to chlamydial infection. The orbit is otherwise believed to be bereft of lymphatic tissue or lymphatic drainage 1. Non-OAML tumors are of a variety of histologies, with diffuse large B-cell lymphoma being relatively common 4.

Orbital lymphomas Abstract Ocular adnexa are those structures and tissues surrounding the globe, such as the conjunctiva, the eyelids, the lacrimal gland, extraocular muscles and orbital fat. Most lymphomas occurring in these sites are low-grade b-cell lymphomas.
The most common form of manifestation is by the presence of periorbital edema, a palpable tumor mass, proptosis and diplopia. Biopsy is essential for accurate diagnosis. Most lymphomas of the ocular adnexa are localized at the moment of diagnosis and radiotherapy is a local treatment showing excellent results. Key words: orbital lymphomas, periorbital edema, palpable tumor masses, proptosis, diplopia, Hodgkin. Los LH son extremandamente infrecuentes en los anexos oculares. Figura 1. Figura 2.
