Combination of phototherapy for treatment of labial necrotizing lesion: case report

Lip necrotizing lesions are painful, complex to heal, and negatively impact the patient's orofacial condition. The present study reports a clinical case of a necrotizing lesion on the lower lip in a 38-year-old male patient, previously healthy, five days after receiving the first dose of the SARS-COV-2 vaccine, with an initial diagnosis of labial herpes zoster, with secondary infection and unsatisfactory response to clinical treatment. After debridement of the necrotic tissue, followed by a combination of antimicrobial photodynamic therapy (aPDT), photobiomodulation therapy (PBMT) and hydrofiber dressing with silver, the patient evolved with complete healing of the lip lesion and satisfactory restoration of orofacial functions after 7 days. According to the present case report, this combination of phototherapy modalities suggests to be a promising tool for the treatment of necrotizing labial lesions.

High-risk mucosal HPV types associated with squamous cell carcinoma on the nose tip in an immunocompetent young man

Abstract: The oncogenic role of high-risk HPV in anogenital, head and neck, and cervical cancer is well recognized, but not in skin cancer in the general population. Some authors have demonstrated their appearance mainly on the hands and feet, particularly in the area of the nail bed, which could be due to contamination with HPV types from anogenital regions. Here, we describe a case of genital HPV associated with SCC on the nose tip in an immunocompetent young man, which was confirmed by histopathological findings and in situ hybridization. The importance of this report is to highlight the potential role of HPV in the etiology of skin cancer in an immunocompetent individual.
