This video shows a cyst on the eyelid. In this case, the lesion is an epithelial inclusion cyst. These benign growths are fluid-filled entrapments internally lined with epithelial cells that continue to produce excretions. Thus, the cyst is filled with debris … in this case keratin. This bump looks yellow and transilluminates, further supporting this diagnosis.
You can remove these many ways. As this case was a “first time” appearance, it was removed at the slit-lamp by slicing horizontally with a needle and expressing the contents with a 0.3 forcep.
