Evaluation of quantitative changes in regulatory T cells in peripheral blood of kidney transplant recipients with skin cancer after conversion to mTOR inhibitors.

Introduction: Immunosuppressive therapy, necessary for graft survival, has its clinical consequences with an increased risk of developing malignancies being one of them. It seems that the maintenance of a proper balance between cytotoxic and regulatory activity of the immune system may prevent graft rejection, and with a lower risk of cancer.

Aim: To assess the quantitative changes in regulatory T cells (Tregs) in peripheral blood of kidney transplant recipients with post-transplantation skin neoplasm after conversion to mTOR inhibitors (mTORi) and to assess the incidence of secondary skin cancer in that group of patients.

Efficacy and Safety of Three Cryotherapy Devices for Wart Treatment: A Randomized, Controlled, Investigator-Blinded, Comparative Study.

Introduction: Cutaneous warts are common skin lesions, caused by human papillomavirus. For years, liquid nitrogen is the cryogen of choice for wart treatment. Alternatively, several cryogenic devices for home treatment are commercially available.

Atopic dermatitis-like pre-Sézary syndrome: role of immunosuppression.

We describe here 4 patients with Sézary syndrome masquerading as adult-onset atopic dermatitis. The patients presented with a clinical picture compatible with wide-spread atopic dermatitis and did not fulfil the criteria for Sézary syndrome (lack of lymphoadenopathy and blood involvement, skin histology without presence of atypical cells). In our patients, overt Sézary syndrome developed after immunosuppressive treatment (including cyclosporine).
