Ocular Adnexal IgG4-Producing Mucosa-Associated Lymphoid Tissue Lymphoma Mimicking IgG4-Related Disease

Abstract: IgG4-related disease is a recently proposed clinical entity with several unique clinicopathological features. A chronic inflammatory state with marked fibrosis, which can often be mistaken for malignancy, especially by clinical imaging analyses, unifies these features. In the present report, we describe a case of IgG4-producing mucosa-associated lymphoid tissue lymphoma mimicking IgG4-related disease. The patient was a 55-year-old male who was being followed for right orbital tumor over 1.5 years. The lesion h… Show more

“…Although IgG4 expression has been described in a single case of a nodal marginal zone lymphoma, 21 few cases of ocular adnexae marginal zone lymphomas, [17][18][19]22 as well as in a subset of marginal zone lymphomas of the dura, 16 the rate of 39% IgG4-positive cases among our primary cutaneous marginal zone lymphomas is striking. Only two IgG4-rearranged primary cutaneous marginal zone lymphomas, identified by RT-PCR, were previously reported.…”

“…This scenario raises the question of a secondary skin involvement by an originally noncutaneous marginal zone lymphoma. 2,6 Given some recent reports that particular subsets of marginal zone lymphomas, specifically epidural and ocular marginal zone lymphomas, [16][17][18][19] show increased frequencies of IgG4 expression and based on the known fact that primary cutaneous marginal zone lymphomas predominantly express IgG in contrast to other marginal zone lymphomas, we were interested to study the prevalence of IgG4 expression in primary cutaneous marginal zone lymphomas in comparison with various noncutaneous marginal zone lymphomas. The concept of IgG4-related diseases has attracted major attention in recent years comprising an ever increasing amount of manifestations of various organs (autoimmune pancreatitis type 1, Mikulicz's disease, Kuttner's tumor, and retroperitoneal fibrosis).…”

“…In such cases, numerous non-neoplastic, IgG4-positive cells can be found among the malignant tumor cells. In contrast, we previously described marginal zone B cell lymphomas in which the tumor cells produced IgG4, which suggests that the infiltrating IgG4-positive cells observed in IgG4-RD can become malignant [10].…”

“…Therefore, symptomatic therapy, such as the appropriate administration of eye drops, in the management of IgG4-related ocular adnexal disease may be appropriate, unless progressive deterioration of eye symptoms is observed. A case of ocular adnexal malignant lymphoma developing in a patient with IgG4-RD during the follow-up period has been reported (28). Therefore, conducting periodical physical examinations, laboratory tests and imaging tests is warranted.…”
