    Abstract Introduction: The COVID-19 pandemic had, in a broad sense, a negative impact on populational health and well-being. Countries around the world struggled to address a spike in demand for the management of viral pneumonia and, at the same time, to efficiently treat the conditions which deteriorate severely when the treatment is delayed. Several studies published so far have analysed the impact of the COVID-19 pandemic on skin cancer epidemiology and management, however the results have been inconsistent.
    Aim: To examine the influence of the COVID-19 pandemic on the cutaneous melanoma epidemiology diagnosed in a tertiary referral centre in Northern Poland.
    Material and methods: This was a retrospective study that gathered the data on all the cutaneous melanoma cases treated in our facility during the official lockdown period in Poland and compared them to those diagnosed during the corresponding period from before the pandemic.
    Results: The number of cutaneous melanoma cases diagnosed during the pandemic decreased substantially. Interestingly, it was mostly due to a decrease in the number of patients with cutaneous melanoma localised on the trunk and early melanoma cases (melanoma in situ and pT1a stage).
    Conclusions: Our data suggest that, similarly to the reports emerging worldwide, the COVID-19 pandemic impaired the capability of our healthcare system to diagnose and treat cutaneous melanoma in our region. The data are limited, and further research will be necessary to determine the whole extent of those changes, especially the long-term effects.

    Abstract Despite rapid growth in the significance of dermoscopy in dermatological oncology, relatively little is yet known about the dermoscopic patterns of eyelid margin tumors. The aim of the study was to analyze the dermoscopic features of eyelid margin tumors. This was a retrospective, single-center, consecutive study which included clinical and dermoscopic analysis of eyelid margin tumors diagnosed at the Department of Dermatology, Venereology and Allergology at the Medical University of Gdańsk from 1 June 2016 to 31 December 2020. Dermoscopic features significantly more prevalent in malignant non-melanocytic lesions compared to benign ones were alteration in eyelash growth, structureless pink areas, starry milia-like cysts, and perpendicular vessels. In contrast, there were no dermoscopic features that occurred significantly more frequently in malignant melanocytic lesions when compared to benign ones. Basal cell carcinoma, in comparison to hidrocystoma, more commonly presented with ulceration and structureless pink areas. The main features differentiating basal cell carcinoma from dermal nevus were the presence of ulceration, alteration in eyelash growth, structureless pink and structureless white areas, and perpendicular vessels within the tumor with each of these features observed more commonly in basal cell carcinoma. Blue nevus, hemangioma, or pigmented hidrocystoma presenting exclusively with blue structureless areas may be difficult to differentiate based on dermoscopy. The study offers additional dermoscopic clues in the assessment of eyelid margin tumors. Some observations reported previously to be typical of basal cell carcinoma (e.g., linear vessels arranged perpendicularly to the eyelid margin) were documented also within the normal eyelid margin accompanying other cases, and according to our study, cannot be useful as a pathognomonic feature. In contrast, it seems that yellow structures (half-moon sign, starry milia-like cysts) may be important dermoscopic features, though further studies are needed to confirm our observations.

    Abstract Introduction: There is growing evidence of the potential uses of dermoscopy in diagnostics of demodicosis. No previous studies have analyzed dermoscopic features in patients with ocular demodicosis.
    Objectives: To evaluate the potential usefulness of videodermoscopy in diagnostics of ocular demodicosis.
    Methods: It was a single-center prospective observational study in which results of videodermoscopic examination of the eyelids were compared to the results of classic microscopic examination in patients with suspected ocular demodicosis and healthy volunteers.
    Results: Study group included 16 women and 15 men. In fifteen (48.4%) patients, microbiological examination of epilated eyelashes was positive. The results of forms filled by the patients concerning known subjective clinical symptoms of ocular demodicosis revealed no significant differences between the group with positive and negative results of microscopic examination. The presence of Demodex tails and madarosis observed during dermoscopic assessment correlated positively with positive results of microscopic examination. At least one Demodex tail was found in 86.7% (13/15) cases with positive results of microscopic examination. In the two remaining cases microscopic evaluation showed the presence of Demodex brevis. In 37.5% (6/16) of patients with negative results of microscopic examination, videodermoscopy showed the presence of Demodex tails.
    Conclusions: Videodermoscopy may facilitate the diagnostics of ocular demodicosis. Patients reporting clinical symptoms suggesting ocular demodicosis but negative results of videodermoscopic examination should be referred to classical microscopic examination to exclude the presence of Demodex brevis. In patients with negative microscopic examination results and symptoms suggesting ocular demodicosis, dermoscopy-guided microscopic re-evaluation could be considered.

    Abstract Mastocytosis is a heterogeneous group of diseases associated with excessive proliferation and accumulation of mast cells in different organs. Recent studies have demonstrated that patients suffering from mastocytosis face an increased risk of melanoma and non-melanoma skin cancer. The cause of this has not yet been clearly identified. In the literature, the potential influence of several factors has been suggested, including genetic background, the role of cytokines produced by mast cells, iatrogenic and hormonal factors. The article summarizes the current state of knowledge regarding the epidemiology, pathogenesis, diagnosis, and management of skin neoplasia in mastocytosis patients.

    Abstract While COVID-19 initially appeared to be manifested primarily by respiratory symptoms, it is now known to be a multi-organ disease, also with dermatological manifestations. Cutaneous symptoms in patients with COVID-19 have a wide clinical spectrum. They may appear at any stage of the disease or as its sole manifestation. Further research is necessary to clarify the pathogenesis of these changes, their prognostic significance and therapeutic management. This article summarizes the current knowledge about changes occurring in the skin, mucous membranes and nails of patients diagnosed with COVID-19 and addresses the issue of drug-induced skin changes associated most common treatments of COVID-19.
