The Community of Madrid installed a provisional hospital at the IFEMA trade show and conference center that provided care to over 4500 COVID-19 patients between March 21 and April 30, 2020. A group of voluntary dermatologists conducted a cross-sectional study in which they examined the mucous membranes of all patients admitted to IFEMA from other hospitals in Madrid. They included patients with pneumonia and a positive polymerase chain reaction test for SARS-CoV-2 or radiological images of COVID-19 without evidence of other causes of pneumonia. The examination of patients was facilitated by the fact that the investigators did not need to change personal protective equipment (PPE) between contacts, as all the patients were examined in a dedicated COVID-19 room.

Enanthema was among the first manifestations to be described. Several cases were mentioned by Galván-Casas et al.,<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> who classified the cutaneous manifestations of COVID-19 into 5 patterns. Jimenez-Cahue et al.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a> later described enanthema in 29% of COVID-19 patients with a skin rash, which mostly took the form of papulovesicular, purpuric, or erythema multiforme–like eruption.</p><p id="par0060" class="elsevierStylePara elsevierViewall">The most frequently described oral manifestation associated with COVID-19 to date is dysgeusia, with rates ranging from 5.6% in early reports from China<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">10</span></a> to 88.8% in a study conducted by ear, nose, and throat specialists.<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">11</span></a> Taste disturbances are highly specific to SARS-CoV-2 infection and may or not be accompanied by a loss of smell.<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">11</span></a> Dry mouth is also very common and is possibly linked to the destruction of salivary glands caused by the binding of the virus to ACE-2 receptors on the glands.<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">12</span></a></p><p id="par0065" class="elsevierStylePara elsevierViewall">We also observed what we consider to be tongue-specific manifestations, such as swelling with characteristic indentation on both sides due to the increased size of the tongue and its pressing against the teeth. This swelling also causes inflammation of the anterior papillae, leading to what we have termed <span class="elsevierStyleItalic">transient U-shaped lingual papillitis</span>. One group of authors reported a case of macroglossia associated with COVID-19 that required treatment with corticosteroids.<a class="elsevierStyleCrossRef" href="#bib0065"><span class="elsevierStyleSup">13</span></a> Tongue swelling and irritated papillae can be caused by multiple factors, including direct inflammation of the oral mucosa by SARS-CoV-2, drying of the mucosa due to viral activity or oxygen therapy, or even poor oral hygiene due to the patient’s situation.</p><p id="par0070" class="elsevierStylePara elsevierViewall">Another highly characteristic finding was glossitis with patchy depapillation, observed in 3.9% of patients in our series. Díaz Rodríguez et al.<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">14</span></a> also reported a case of depapillation, interestingly associated with a burning sensation in the mouth. Another more recently described oral manifestation is COVID tongue,<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">15</span></a> which is similar to geographic tongue but characterized by an increased incidence in patients with SARS-CoV-2 infection. It might be caused by direct binding of the virus to ACE-2 receptors on the tongue or by an increased expression of interleukin 6, which has been described in patients with COVID-19 and patients with geographic tongue. Further studies are needed to better understand this association and its possible etiology and pathogenesis.</p><p id="par0075" class="elsevierStylePara elsevierViewall">Mouth ulcers and aphthous stomatitis have also been described in patients with COVID-19, and in some cases as an early sign of infection<a class="elsevierStyleCrossRefs" href="#bib0080"><span class="elsevierStyleSup">16,17</span></a>; mucositis and aphthous lesions in the mouth have been linked to infections by other viruses, such as herpes simplex and cytomegalovirus.</p><p id="par0080" class="elsevierStylePara elsevierViewall">The sensation of a burning tongue or burning mouth syndrome has also been previously described in association with COVID-19. One Italian study of oral manifestations in 20 COVID-19 patients found that 15% had the sensation of a burning mouth<a class="elsevierStyleCrossRef" href="#bib0090"><span class="elsevierStyleSup">18</span></a>; this rate is somewhat higher than that of 5.3% detected in our series. The authors of an Iranian study reported a prevalence rate of 68% for oral manifestations of COVID-19 classified into pain, burning, and pruritus.<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a> These manifestations could have a neurological origin as palmoplantar erythrodysesthesia has also been described in COVID-19.<a class="elsevierStyleCrossRef" href="#bib0095"><span class="elsevierStyleSup">19</span></a> A burning sensation in the mouth or on the palms and soles could be a sign of SARS-CoV-2 infection.</p><p id="par0085" class="elsevierStylePara elsevierViewall">Oral manifestations in patients with COVID-19 might be due to SARS-CoV-2-mediated hemolysis (erythrocytes have ACE-2 receptors). The virus might compete with hepcidin, causing increased levels of serum ferritin and, paradoxically, anemia and iron deficiency. Like patients with iron deficiency, they could experience ulcers and a burning sensation in the mouth.<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">20</span></a></p><p id="par0090" class="elsevierStylePara elsevierViewall">There have also been reports of new-onset halitosis in patients with COVID-19. Using a halimeter, one group of authors found that patients had increased sulphur compound levels during active SARS-CoV-2 infection and normal levels afterwards.<a class="elsevierStyleCrossRef" href="#bib0105"><span class="elsevierStyleSup">21</span></a> As possible reasons, the authors proposed primary, virus-mediated, alterations to the oral mucosa or secondary alterations related to dry mouth and decreased salivary flow.</p><p id="par0095" class="elsevierStylePara elsevierViewall">Possible sources of bias in our study are its cross-sectional design (we do not know the history or outcomes of the lesions identified) and our exclusive focus on patients with pneumonia (we do not know whether patients with few or no symptoms might have developed similar lesions).
