Basal cell carcinoma (BCC), the most common human malignancy, accounting for 75% of all non-melanoma skin cancer, is uncommon on unexposed skin such as the perianal and genital regions. We describe a woman with BCC of the vulva treated with local resection. All margins of excision were free of disease. The patient recovered without complication and there have been no recurrences after 2 years of follow-up. Approximately 200 cases of BCC on perianal and genital skin have been reported in the literature. Although the aetiology of vulvar BCC is not known, early diagnosis is important. Because BCC in these sites sometimes seems innocuous, biopsy of all suspect lesions is advisable.

Peripheral eosinophilia is almost invariably observed during the course of interleukin-2 (IL-2) therapy and is frequently accompanied by the development of a capillary leak syndrome characterized by edema, weight gain, and oliguria. We studied five patients with advanced malignancy treated with IL-2. Eosinophilia was not present initially but developed in all patients late in the course of therapy, with counts ranging from 2,328/mm3 to 15,958/mm3. In all patients, there was a temporal relationship between the infusion of IL-2 and the appearance of elevated plasma concentrations of IL-5, a growth factor for eosinophils. Granulocyte-macrophage colony-stimulating factor was not detectable in plasma. IL-4 and gamma-interferon plasma levels were variably elevated. Plasma concentrations of major basic protein, a toxic eosinophil granule protein, began increasing before eosinophil counts increased. By the time of the third IL-2 infusion, high concentrations of major basic protein were present in all five patients (up to 5,600 ng/mL) and skin biopsies showed major basic protein deposition in the dermis. Four patients developed significant capillary leak syndrome and all of these patients showed markedly elevated major basic protein levels. The lowest peak plasma concentration of major basic protein (1,751 ng/mL) was observed in the one patient who did not develop edema and weight gain. These results suggest that IL-2 induces IL-5 leading to marked peripheral eosinophilia and extravascular eosinophil degranulation. The release of toxic eosinophil products at extravascular sites and in the circulation may contribute to the pathogenesis of the capillary leak syndrome complicating IL-2 therapy.

On January 30, 2020, World Health Organization (WHO) stated that a new coronavirus disease outbreak [COronaVIrus Disease - 19 (COVID-19)] was an international public health emergency. Many news, often fake ones, about the derived pandemic rapidly spread along the media, thus leading many dermatological patients to identify as “risk category” and sometimes discontinue treatments by themselves. The Dermatology Units in Grosseto and Pordenone simultaneously carried out a data collection by remote-conducted visits, evaluating the incidence of COVID-19 in psoriatic patients. Only 1 patient (close contact of a case) as part of the psoriasis analyzed group was tested and turned out to be positive for SARS-CoV-2, developing no symptoms during the observation period. The collected information may suggest that psoriasis, biotechnologically treated or not, cannot promote or aggravate the clinical trend of the SARS-CoV-2 infection, hence stopping systemic therapy in negative or clinically free SARS-CoV-2 patients is not recommended in general.

Genital involvement is a rare manifestation in discoid lupus erythematosus (DLE) and systemic lupus erythematosus (SLE), and there are few reports on vulvar clinical features. We describe a 41-year old Caucasian woman with bilateral vulvar DLE. Although vulvar lesions in lupus are probably more common than is realized, the present report is the first case of genital DLE documented in a female.
