At the beginning of the pandemic, pulmonary issues were the most discussed and studied. However, now 3 years later, the role of the dermatologist has become increasingly central. Often the diversity in the presentation of these manifestations has made it difficult for the dermatologist to recognize them. In addition to the common symptoms involving fever, cough, dyspnea, and hypogeusia\/hyposmia that have been widely discussed in the literature, much attention has been paid to dermatologic manifestations in the past year. The vaccination campaign has been the most important strategy to combat the COVID-19 pandemic. Specifically, two viral vector-based vaccines [Vaxzervria\u00ae (AstraZeneca; AZD1222) and COVID-19 Janssen\u00ae vaccine (Johnson &amp; Johnson; Ad26.COV2. S)] and two mRNA-based vaccines [Comirnaty\u00ae (Pfizer\/BioNTech; BNT162b2) and Spikevax\u00ae (Moderna; mRNA-1273)]. However, several cutaneous adverse reactions have been reported following vaccination, making the dermatologist\u2019s role critical. It is possible to group these adverse reactions according to a classification with six main clinical pictures: urticarial rash, erythematous\/maculopapular\/morbid rash, papulovesicular rash, chilblain-like acral pattern, livedo reticularis\/racemose-like, and purpuric \u201cvasculitic\u201d pattern. Beyond this classification, there are several reports of other dermatologic manifestations associated with the infection, such as pityriasis rosea, herpes zoster, or, particularly, the worsening of pre-existing chronic inflammatory dermatologic diseases. Here we report the case of a 61-year-old patient who presented at our clinic with a diffuse psoriasiform eruption mixed with a concomitant blistering rash induced by COVID-19. The uniqueness of our case has two features: the first is the concomitance of the two events after infection that seems to be unprecedented; the second is the management of the patient that could help dermatology colleagues in the management of these conditions during infection.<\/jats:p>","DOI":"10.3390\/tropicalmed8020107","type":"journal-article","created":{"date-parts":[[2023,2,8]],"date-time":"2023-02-08T05:37:31Z","timestamp":1675834651000},"page":"107","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Concomitant Severe Psoriasis and Bullous Pemphigoid Induced by COVID-19"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2523-050X","authenticated-orcid":false,"given":"Fabrizio","family":"Martora","sequence":"first","affiliation":[{"name":"Dermatology Unit, Department of Clinical Medicine and Surgery, University of Naples Federico II, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teresa","family":"Battista","sequence":"additional","affiliation":[{"name":"Dermatology Unit, Department of Clinical Medicine and Surgery, University of Naples Federico II, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriella","family":"Fabbrocini","sequence":"additional","affiliation":[{"name":"Dermatology Unit, Department of Clinical Medicine and Surgery, University of Naples Federico II, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1803-2046","authenticated-orcid":false,"given":"Matteo","family":"Megna","sequence":"additional","affiliation":[{"name":"Dermatology Unit, Department of Clinical Medicine and Surgery, University of Naples Federico II, 80131 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"71","DOI":"10.1111\/bjd.19163","article-title":"Classification of the cutaneous manifestations of COVID-19: A rapid prospective nationwide consensus study in Spain with 375 cases","volume":"183","year":"2020","journal-title":"Br.
