The coronavirus disease 2019 (COVID-19) pandemic has led to lockdowns for much of the world. In Italy, all health procedures not directly related to COVID-19 were reduced or suspended, thus limiting patient access to hospitals. Any delay in cancer treatment presents the additional risk of tumors progressing from being curable to incurable.

Article Synopsis
  • A multicenter study examined the effectiveness and safety of using 755 nm Alexandrite and 1064 nm ND:YAG lasers to treat various skin vascular lesions in 171 patients, mostly women aged 38 on average.
  • The types of lesions included spider angiomas, facial and leg telangiectasia, and port wine stains, requiring varying numbers of treatment sessions for significant improvement, with facial telangiectasias needing 1 to 4 sessions and port wine stains needing 6 to 9.
  • The study found that the sequential laser treatment led to marked improvement in all cases with minimal side effects, primarily low pain and temporary changes, making it a promising method for treating aesthetic issues caused by vascular lesions.

Granuloma faciale (GF), also known as "eosinophilic granuloma," is a rare benign leukocytoclastic vasculitis which most commonly occurs on the face of middle-aged Caucasian males. Clinically, GF appears as single or multiple, slowly growing, reddish-brown papules, nodules or plaques which may be cosmetically unpleasant. Its pathogenesis is unknown and GF is notoriously resistant to treatments.

Background/purpose: Many aspects of the natural history of malignant melanoma (MM) are still unclear, specifically its appearance at onset and particularly how it changes in time. The purpose of our study was to retrospectively determine objective changes in melanoma over a 3-24-month observation period.

Materials And Methods: Our study was carried out in two Italian dermatology centers.

Various authors have suggested that information from longitudinal observation (follow-up) of dynamic changes in atypical melanocytic pigmented skin lesions (MPSL) could enable identification of early malignant melanoma escaping initial observation due to an absence of specific clinical and dermoscopic features. The aim of our retrospective study was to determine the existence of numerical variables regarding changes in MPSL that could be useful to differentiate early melanomas and atypical nevi. The study was carried out in two Italian dermatology Centres.

Digital dermoscopy analysis (DDA) exploits computerized analysis of digital images and offers the possibility of parametric analysis of morphological aspects of pigmented skin lesions by means of integration with dedicated software. We conducted a study by DDA in 141 melanomas, with the aim assessing whether the numerical variables extrapolated by univariate logistic analysis could be used in a system of multivariate analysis to predict melanoma thickness before surgery. Melanoma images were evaluated for 49 DDA parameters.

Recent studies indicate that mesenchymal stem cells (MSC) exhibit a degree of immune privilege due to their ability to suppress T cell mediated responses causing tissue rejection; however, the impact of allogeneic MSC in the setting of organ transplantation has been poorly investigated so far. The aim of our study was to evaluate the effect of intravenous donor MSC infusion for clinical tolerance induction in allogeneic skin graft transplantations in rats. MSC were isolated from Wistar rats and administered in Sprague-Dawley rats receiving Wistar skin graft with or without cyclosporine A (CsA).

Background: Kaposi's sarcoma (KS) is a lymphangioproliferative tumour. Therapy of KS depends on the characteristics of the disease, especially area and growth rate of lesions, and patient condition. Currently symptomatic resectable lesions are excised, whereas more advanced disease and unresectable lesions are treated with radiotherapy.

Objectives: Pityriasis lichenoides chronica (PLC) is a skin disease of unknown etiology. Uncertainty about the etiopathogenesis of this skin disease is the reason for the unpredictable and non optimal efficacy of therapies available for its treatment. The aim of the present study was to evaluate the efficacy of bromelain, a crude aqueous extract of the stems and immature fruit of pineapple, in the treatment of PLC.

Background: Very few studies have tried to clarify how pregnancy influences the morphology of pigmented skin lesions (PSL). Our purpose was to objectively determine, by digital dermoscopy analysis (DDA), any dermoscopic changes of acquired melanocitic nevi during pregnancy and after 1 year from delivery.

Methods: Thirty-five healthy pregnant women and 35 age-matched female controls were enrolled in the study.

We report the case of a patient who presented with painful nodular subcutaneous lesions on the lower limbs and episodes of high temperature (> 39.5 degrees C). Histologic examination and immunohistochemical study of a biopsy specimen from a nodular lesion were consistent with the diagnosis of subcutaneous panniculitis-like T-cell lymphoma, a rare form of non-Hodgkin lymphoma.

Idiopathic hypereosinophilic syndrome (IHES) is a rare condition of uncertain etiology characterized by marked peripheral blood eosinophilia and organ system dysfunction that cannot be explained by any factor other than the presence of eosinophils or their potentially toxic products. Diagnostic criteria include 1) a sustained eosinophilia greater than 1500/mm for longer than 6 months, 2) absence of other causes of eosinophilia, including parasitic infections and allergic diseases, and 3) multiorgan involvement (ie, lungs, heart, central nervous system, skin, liver, joints). Steroids represent the initial therapeutic approach, although for those patients unresponsive to steroids, cytotoxic chemotherapy should be considered.

Background: Postmortem skin is widely used in the treatment of patients with severe burns. Skin specimens must be screened for transmissible agents including human immunodeficiency virus (HIV), hepatitis B (HBV) and C (HCV) virus, human T-cell lymphotropic virus (HTLV), cytomegalovirus (CMV) and Treponema pallidum.

Methods: Four hundred and sixty-one cadaveric donors underwent serological and molecular microbiological (polymerase chain reaction, PCR) screening at Siena Skin Bank between 2000 and 2004.

The main use of homologous skin grafts or grafts of related bioproducts is in the treatment of severe burns. However, various new clinical and experimental sectors, in which this type of skin substitute can be useful, have recently emerged. The main new clinical indications for skin allografts include: skin loss, surgical wounds and bullous diseases.

Increasing use of suction-socket lower limb prostheses has been associated with an increased frequency of dermatological manifestations, linked to the fact that the skin of the amputation stump must adapt to an entirely new environment. In particular, verrucous hyperplasia and rare cases of acroangiodermatitis (pseudo-Kaposi sarcoma) have been described. We report a case of amputation stump dermatitis, clinically resembling verrucous hyperplasia, but with predominant histological aspects of acroangiodermatitis in a patient with a suction-socket lower limb prosthesis.

Background: In recent years, many non-invasive instruments have been used to examine the correlation between transcutaneous bilirubin (TcB) measurements and serum concentrations of bilirubin (SB) in newborns with a view to reducing the need for blood samples. However, their exact role has not been univocal. The aim of the present study was to determine whether non-invasive measurement of skin colour combined with appropriate clinico-statistical methodology can be used to better quantify SB in the first days of life.
