WEDNESDAY July 15, 2020 (HealthDay News) – While rashes on the skin have long been linked to COVID-19, doctors in Spain report that rashes inside the mouth also occur in some cases.
The rashes are clinically known as enanthem, and it’s no surprise that they show up with COVID-19, a U.S. dermatologist unrelated to the new study said.
“An enanthem is a rash [small spots] on mucous membranes, “explained Dr. Michele Green, who practices at Lenox Hill Hospital in New York.” It is very common in patients with viral infections like chickenpox and foot-and-mouth disease. It is characteristic of many viral rashes to affect the mucous membranes. “
The new Spanish study was published on July 15 in JAMA Dermatology. Researchers led by Dr. Juan Jimenez-Cauhe, from the Ramon y Cajal University Hospital in Madrid, examined 21 patients diagnosed in early April with COVID-19 and associated rashes.
Among these patients, six patients (29%) had an enanthemum inside the mouth. Affected patients were between 40 and 69 years old, the team said, and four of the six were women.
The mouth rash appeared between two days before the onset of other COVID symptoms and 24 days after, with an average delay of about 12 days after the onset of symptoms.
In most cases, the enanthemum did not appear to be related to any medication that the patients were taking, which further reinforced the notion that it was a disease with the new coronavirus causing the appearance of reddish spots.
It is still unknown how common this symptom is with COVID-19, because “due to safety concerns, many patients with suspected or confirmed COVID-19 do not have their oral cavity examined,” the group noted. Jimenez-Cauhe.
