An Unusual Case of Extranodal Rosai-Dorfman Disease Manifesting as an Epibulbar Mass.

Purpose: To report an unusual presentation of a 48-year-old man with a salmon-colored epibulbar mass, whose pathology was consistent with extranodal Rosai-Dorfman disease (RDD).

Method: We conducted a retrospective and interventional case report.

Results: A 48-year-old white man presented with progressive left eye irritation, redness, and multiple large subcutaneous nodules on his arms and torso over the past year.

Characterization of retinal and blood mitochondrial DNA from age-related macular degeneration patients.

Purpose: To determine mitochondrial (mt)DNA variants in AMD and age-matched normal retinas.

Methods: Total DNA was isolated from retinas (AMD, n = 13; age-matched normal, n = 13), choroid (AMD, n = 3), and blood (AMD, n = 138; normal, n = 133). Long-extension-polymerase chain reaction amplified the full-length ( approximately 16.
