摘要
Lymphomas are known as neoplasm’s caused by clone proliferation of B and T lymphocytes. Extranodal lymphoma arises from tissues other than lymph nodes or even from sites which normally doesn’t contain lymph tissues. Orbital adnexal lymphoma arises from eyelid, orbit, lacrimal glands or conjunctivae and it is totally different from intraocular lymphoma. Wide range of differential diagnosis including infectious inflammatory orbital disease, preseptal and orbital cellulitis, orbital idiopathic inflammatory disease-pseudotumors, especially dacryoadenitis and myositis and thyroid associate orbit disease makes the diagnosis of orbital adnexal lymphoma even more difficult. We represent the case of diagnostic delay of very aggressive form orbital non-Hodgkin lymphoma occurred because of the unspecific signs and symptoms as well as not indicative imaging investigation and laboratory tests.
