Unexplained growth of mysterious goo on woman's tongue baffles experts

A woman in Mexico developed a rare lump on her tongue caused by oral focal mucinosis (OFM), a connective tissue disorder that typically forms masses on the gums or hard palate. OFM of the tongue is even more unusual. The lump was caused by an excessive production of hyaluronic acid, resulting in a buildup of gelatinous goop. The woman underwent surgery to remove the lump, and it did not recur after 10 months of monitoring. The cause of OFM is still unknown, but some scientists believe it may be triggered by physical trauma.
