Background Merkel cell carcinoma (MCC), a rare cutaneous neuroendocrine endocrine tumour is increasing in incidence, and continues to carry a poor prognosis. Objectives The objectives of this study were to examine all Irish cases of MCC from 1 January 1994 over 2 decades, focusing on gender and organ transplantation recipients (OTRs). Cases were identified from the National Cancer Registry of Ireland. Covariates of interest included age, body site, period of diagnosis, deprivation‐status and history of non‐melanoma skin cancer (NMSC). Results In total 314 MCC cases were identified. A female predominance was noted (53.8%). Comparison between age‐standardised rates between the earliest period (1994–1996) with the latest period (2012–2014) showed an increase of 105% in total. The trend in age‐standardised incidence rates were noted to be increasing significantly (p = 0.0004). Average age at diagnosis was 77.6 years (male 75.1 years, female 79.7 years). Overall, the majority of MCC cases presented on the head and neck (n = 170, 54.1%). Differences in anatomical location of MCCs were noted between genders. Males were found to be more likely to have a history of previous NMSCs (males n = 73 [57.9%], females n = 53 [42.1%]). Thirty‐one percentage of patients died from MCC, average survival was 3.5 years in those who died of this malignancy. Ten organ transplant recipients developed MCC. OTR who developed MCC were diagnosed at a younger average age of 65.1 years. Standardized incidence ratio for MCC in OTR was 59.96. A higher proportion of OTR died from MCC (70%), with a shorter median survival of 0.14 years. In competing risks regression, gender was not significantly associated with risk of dying, females having a non‐significantly higher hazard of dying. Organ transplant recipients and patients from less deprived areas were at greater risk of dying from MCC. Conclusions This population based study provides epidemiological, clinical and outcome data for MCC over a 20‐year period.

Higher rates of morbidity and mortality due to coronavirus disease (COVID-19), caused by infection with severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), are associated with increasing age, gender, and a variety of comorbidities. Given the apparent risk of infection from viral diseases in patients receiving immunomodulatory medications, we surveyed a sample of our dermatology patients on these treatments regarding their knowledge and perceived risk to the novel coronavirus. The phone call survey was carried out from 27 March 2020 to 3 April 2020 and included questions on demographics, comorbidities, immunomodulatory agent, and concern regarding immunosuppression. Self-isolation, knowledge of viral

We present an unusual case of Mondor disease (MD) occurring secondary to elliptical excision of a naevus on the chest wall. MD is a rare superficial thrombophlebitis classically occurring on the anterolateral thoracoabdominal wall. It can be idiopathic, can be due to trauma, breast malignancy, hypercoagulable states or can be iatrogenic, most commonly arising from breast surgery. The condition is generally self-resolving within weeks.
