Clinical features and symptoms of IgG4-related ophthalmic disease: a multicenter study.

Purpose: The aim of this study was to elucidate the clinical features and symptoms of IgG4-related ophthalmic disease (IgG4-ROD).

Study Design: Retrospective, multicenter study.

Methods: The medical charts of 378 patients with IgG4-ROD diagnosed at 9 hospitals in Japan were reviewed.

Treatment outcomes of IgG4-producing marginal zone B-cell lymphoma: a retrospective case series.

IgG4-producing marginal zone B-cell lymphomas (MZLs) have been recently proposed as a subtype of MZLs. Despite the abundant literature on pathophysiological features of this type of lymphoma, only a few retrospective studies pertaining to the treatment outcomes have been reported, and its prognosis remains unclear. We retrospectively analyzed seven patients with IgG4-producing MZLs diagnosed at our institute, with specific reference to treatment and outcomes.

Ocular adnexal marginal zone lymphoma arising in a patient with IgG4-related ophthalmic disease.

A 41-year-old man was diagnosed with immunoglobulin G4-related disease (IgG4-RD) in both eyelids 4 years ago and exhibited good response to steroid therapy. However, rapid swelling of the right eyelid lesion was recently observed. As IgG4-RD progression was suspected, biopsy was performed.

Location and frequency of lesions in patients with IgG4-related ophthalmic diseases.

Background: It is well-known that the lacrimal gland (LG) may be affected in IgG4-related ophthalmic disease (IgG4ROD). Recently, IgG4-related ophthalmic lesions other than those of the lacrimal gland have been reported. However, no study to date has revealed the details of these lesions.

A case of conjunctival follicular lymphoma mimicking mucosa-associated lymphoid tissue lymphoma.

Ocular adnexal lymphoma may involve the eyelids, conjunctiva, orbital tissue, or lacrimal structures. The majority are non-Hodgkin's B-cell lymphomas of mucosa-associated lymphoid tissue (MALT) lymphoma type. Follicular lymphomas represent a small percentage of ocular adnexa lymphomas, particularly in Japan.

Pathological findings of infraorbital nerve enlargement in IgG4-related ophthalmic disease.

Purpose: We report a case of bilateral infraorbital nerve enlargement (IONE) associated with immunoglobulin (Ig)G4-related ophthalmic disease and describe the associated histopathologic findings.

Case: An otherwise healthy 59-year-old man presented with bilateral exophthalmos and right visual disturbance. Orbital magnetic resonance imaging showed bilateral IONE and a soft tissue mass in the right orbit.

The usefulness of infraorbital nerve enlargement on MRI imaging in clinical diagnosis of IgG4-related orbital disease.

Purpose: To investigate the frequency of infraorbital nerve enlargement (IONE) in orbital lymphoproliferative disorders, and to show that IONE can contribute to the clinical diagnosis of IgG4-related orbital diseases (IgG4-ROD).

Subjects And Methods: 71 cases in which orbital lymphoproliferative disorders were diagnosed at Okayama Medical Center and Mitoyo General Hospital from April, 2004 to March, 2011 were investigated. The male-to-female ratio was 39:32, and the age range 27-87 years old (average age 64.
