Several studies have investigated the prevalence and diversity of HPV types in the three main types of skin warts: common, plantar, and flat warts. Using different methodological approaches and diverse populations, several HPV types were detected in skin warts, but often the etiological link remained unconfirmed. This review addresses recently improved multiple strategies for investigating the presence of HPVs in skin warts, covering proper sampling techniques for HPV testing, choice of molecular method(s) for HPV detection, and assignment of the etiological causality of the tested skin wart to a causative HPV type using cellular viral load estimation. These novel approaches provide useful insight into the range of HPV types causing skin warts and support a refined understanding of their etiology. In addition, we conducted a literature review of the main studies examining HPV prevalence and genotype distribution in common warts, plantar warts, and flat warts.

We present the case of a 70-year-old man with CLL in remission (previously treated with two 6-month cycles of fludarabine-cyclophosphamide plus rituximab, 2 and 5 years earlier) with an acute, disseminated polymorphic skin eruption.

The pathologist reported giant spongiform vesicle formation with eosinophils with dermal and hypodermal inflammatory infiltrate composed of lymphocytes (predominantly T cells, fewer B cells) and eosinophils. Secondary neoplasm dissemination and sarcoidosis were excluded by means of immunohistochemistry. A diagnosis of eosinophilic eruption of hematoproliferative disease in the CLL patient post-chemotherapy and without active disease was established. Two weeks after skin remission, the patient worsened with enlarged lymph nodes and a leukocyte count of 291 × 10^9/l. CLL relapse was confirmed.

The use of PPE has been associated with mask-related acne due to microbiome dysbiosis and disruption of skin homeostasis, leading to the emergence of new acne or exacerbation of preexisting acne. Chilblain-like lesions, erythema multiforme-like eruptions, and cutaneous manifestations of multisystem inflammatory syndrome related to SARS-CoV-2 are the most commonly described skin manifestations of SARS-CoV-2 infection.
