Treatment outcomes and their determinants of IgG4-related ophthalmic disease: a territory-wide cohort study.

Background: Oral corticosteroid remains the first-line treatment of IgG4-related ophthalmic disease, but steroid-dependence is common and serious. Factors associated with steroid dependence and relapse have to be further explored.

Study Population: A city-wide, biopsy-proven, Chinese cohort.

Radiological Determinants of Complicated Immunoglobulin G4-Related Ophthalmic Disease: A Territory-Wide Cohort Study.

Purpose: To evaluate the presenting radiological features of immunoglobulin G4-related ophthalmic disease (IgG4-ROD) and their associations with IgG4-related optic neuropathy (IgG4-RON), and IgG4-related ocular adnexal lymphoma (IgG4-ROL).

Methods: A territory-wide, biopsy-proven, Chinese cohort. Masked review of orbital images, medical records, and histopathology reports.

Malignancies in Immunoglobulin G4-related ophthalmic disease.

Purpose: Clinical phenotypes in Immunoglobulin G4-related disease (IgG4-RD) according to the patterns of affecting organs have different risks of malignancies. We attempt to determine the association of malignancies with IgG4-related ophthalmic disease (IgG4-ROD).

Design: Retrospective cohort study.

Ocular PEComas are frequently melanotic and TFE3-translocated: report of two cases including the first description of PRCC-TFE3 fusion in PEComa.

Ocular perivascular epithelioid cell tumor (PEComa) is exceedingly rare. We reported two examples involving the choroid and subconjunctival tissue, respectively, in patients aged 17 and 20 years. Both tumors comprised packets and sheets of large polygonal cells with moderately pleomorphic nuclei and prominent nucleoli, traversed by delicate fibrovascular septa.

Muir-Torre Syndrome in a Middle-Aged Chinese Patient with Sebaceous Carcinoma of the Eyelid.

Muir-Torre syndrome is a rare, autosomal dominant condition characterized by the presence of a skin tumor of sebaceous differentiation and visceral malignancies. We reviewed the case of a 46-year-old Chinese man who had a bleeding mass over the right upper eyelid. He had a history of colon cancer and a family history satisfying the Amsterdam criteria for hereditary non-polyposis colorectal cancer syndrome with germline mutation in the MutS homolog-2 gene.
