There is little evidence regarding the impact of COVID-19 lockdown on skin tumour burden. The COVID-19 lockdown resulted in a reduction in surgery for melanoma and cutaneous squamous cell carcinoma and an increase in the proportion of tumours with a worse prognosis. The increase was due to patient-dependent factors; in particular, fear of SARS-CoV-2 infection. Therefore, health education programmes targeting the general population are needed to ensure the prompt treatment of patients with skin cancer. The aim of this study was to compare tumour burden in patients who underwent surgery for melanoma and cutaneous squamous cell carcinoma during nationwide lockdown inSpain due to COVID-19 (for the period 14 March to 13 June 2020) and during the same dates in 2019 before the COVID-19 pandemic. In addition, associations between median tumour burden (Breslow thickness for melanoma and maximum clinical diameter for cutaneous squamous cell carcinoma) and demographic, clinical, and medical factors were analysed, building a multivariate linear regression model. During the 3 months of lockdown, there was a significant decrease in skin tumours operated on (41% decrease for melanoma (n = 352 vs n = 207) and 44% decrease for cutaneous squamous cell carcinoma (n = 770 vs n = 429)) compared with the previous year. The proportion of large skin tumours operated on increased. Fear of SARS-CoV-2 infection, with respect to family member/close contact, and detection of the lesion by the patient or doctor, were related to thicker melanomas; and fear of being diagnosed with cancer, and detection of the lesion by the patient or relatives, were related to larger size cutaneous squamous cell carcinoma. In conclusion, lockdown due to COVID-19 has resulted in a reduction in treatment of skin cancer.
Lentigo maligna is a type of in situ melanoma. It develops mainly in middle-aged and elderly individuals on areas of the skin chronically exposed to sunlight. It progresses to its invasive form, lentigo maligna melanoma, in 5% to 50% of cases. Management of lentigo maligna is open to debate, with a notable lack of randomized trials and specific guidelines and protocols. Early diagnosis and treatment is necessary to achieve cure if possible and prevent progression to invasive melanoma with the corresponding risk of metastasis. The treatment of choice for lentigo maligna is surgery. When surgery is not possible, other alternatives are available although outcomes and rates of recurrence are variable. The objective of this study was to review the diagnostic methods and criteria for lentigo maligna, as well as the different surgical options and alternatives to surgery, in order to provide information on the best approach in each case.
We report the case of a 5-year-old boy who had a temporary dragon-shaped henna pseudotattoo, reinforced 4 days later. Two weeks later, as the pseudotattoo began to disappear, hypertrichosis developed in the area corresponding to the previous psuedotattoo. Skin biopsy showed an increase in vellus hair follicles, with slight peripheral fibrosis. After 4 months, the hypertrichosis resolved spontaneously.
We report an unusual case of molluscum contagiosum associated with pseudolymphoma in an otherwise healthy young woman. She presented with a 2‐week history of a rapidly enlarging painful umbilicated nodule behind her right ear. With the clinical presentation suspicious for a tumoral lesion, we decided to remove it surgically. Histological examination showed a florid cellular infiltrate surrounding a typical lesion of molluscum contagiosum. The infiltrate was composed of small to large pleomorphic lymphocytes. However, clonal TCR rearrangement could not be demonstrated. As far as we know this is the first case where the clinical picture is shown.
Adjuvant interferon-α2b (IFN-α2b) has been studied extensively in clinical trials, but there have been few studies of real-world use. The aim of this study is to describe the IFN-α2b real-world patterns in patients with high-risk melanoma in Spain. This was a retrospective and multicentre chart review study of an unselected cohort of patients with melanoma at high risk for relapse (stage IIB/IIC/III) treated with IFN-α2b. Patterns were assessed in terms of dose and compliance to planned treatment. A survival analysis was carried out for the full population and according to Kirkwood scheme compliance and the presence of ulceration. Of 327 patients treated with IFN-α2b, 318 received a high-dose regimen following the standard Kirkwood scheme; thus, patterns are described for this regimen. A total of 121 (38%) and 88 (28%) patients had at least one dose reduction during the induction and maintenance phases, respectively. Dose delay was required in fewer than 10% of patients. A total of 78, 40 and 38% of the patients completed the induction phase, maintenance phase and completed treatment, respectively. The median progression-free and overall survival for the full population were 3.2 and 10.5 years, respectively. There were no differences in progression-free survival and overall survival according to Kirkwood scheme compliance and the presence of ulceration. The most frequent adverse events were neutropenia (31%) and fatigue (30%). High-dose IFN-α2b is the most frequently used regimen in Spain as an adjuvant systemic treatment for high-risk melanoma. Despite poor compliance, in this retrospective study, IFN-α2b treatment provided a benefit consistent with that described previously.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
