"Patients who do not have conjunctival involvement (75% of cases) present with an orbital mass, usually in the superior lateral quadrant, in proximity to the lacrimal gland 1,6:"
"An association between Chlamydia psittaci infection and orbital adnexal MALT lymphoma has been described 1,2. Infection by Chlamydia psittaci is usually the result of exposure to infected birds and household pets. Patients may go on to develop psittacosis, usually with respiratory tract manifestations 3."
"Orbital adnexal MALT lymphoma (OAML) has a better prognosis than other types of orbital lymphomas and are, not surprisingly, more often conjunctival. The identification of Chlamydia psittaci as a likely important causative factor in the increasing incidence of orbital lymphomas has lead to antibiotic therapy being used to reduce the size of the tumour and in some cases results in remission 1-3."
"Generally the mass is painless; however, a subset of patients demonstrates inflammatory-like changes, including pain, erythema, and swelling 1."
