What are small, white epithelial cysts found on a baby's skin known as?

Small, white epithelial cysts found on a baby's skin are known as Epstein's Pearls. These cysts are formed from the accumulation of keratin and are typically located along the midline of the hard palate or on the gums. They are benign and common among newborns, often appearing shortly after birth. While they may look concerning, Epstein's Pearls usually resolve on their own without treatment and are completely harmless.

The other terms relate to different skin features or conditions: nevi refer to moles or birthmarks, hemangiomas are vascular tumors commonly seen in infants, and vernix caseosa is the thick, white, cheese-like substance that coats the skin of a newborn before birth. Each of these has its own specific characteristics and implications, distinguishing them from Epstein's Pearls.
