A 27-year-old dental radiographer presented to a clinic with red lesions on his palate, right lower and mid-upper lip, as well as one of his fingers. These lesions were accompanied by slight pain, and the patient had a low-grade fever 1 week before the appearance of the lesions. The patient touched the affected area repeatedly, which resulted in bleeding. Two days prior to his visit, he observed a small vesicular eruption on his right index finger, which merged with other eruptions and became cloudy on the day of the visit. He has not had similar symptoms previously. He did not report drug usage. A Tzanck smear was prepared from scrapings of the aforementioned lesions by the attending physician, and multinucleated epithelial giant cells were observed microscopically. According to the clinical presentation and histologic finding, which viral infection should be suspected in this case?
