Abstract： To the editor:We present a fast growing conjunctival melanoma within 3 weeks after injury from the earthquake,which from a rice-size (about 3.0 mm x 4.0 mm) one proliferated rapidly into a giant mass with a size of 5.7 cm x 3.4 cm.A 76-year-old female who lived in Dujiangyan city,Sichuan,China,near the epicenter of the Wenchuan earthquake,was admitted into hospital for a fast growing big mass in the right orbit within 3 weeks.More than half a year ago,the patient found "a painless,rice-size,brown spot" (about 3.0 mm × 4.0 mm) in the temporal surface of right conjunctiva,and it did not change much.Three weeks ago,the Wenchuan earthquake happened,she fell down,the "rice-size brown spot" abrasion,and subconjunctival hemorrhage in the right eye occurred.Two weeks ago,the original rice-size spot grew into a big mass with discharge on the surface.
