Those proteins are responsible for the intercellular contact between epidermal keratinocytes and adhesion of the basal keratinocytes to the dermis. Therefore, AIBDs are divided into two main groups: intraepidermal (the pemphigus group) and subepidermal (the pemphigoid) groups. The diagnostic methods for AIBDs have made tremendous progress in the last 2 decades due to the availability of standardized serological assays that allow precise diagnosis in most patients. If left untreated, these diseases are potentially life-threatening due to superinfections and loss of body fluids, and in some severe cases due to restricted food intake.

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.

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.
