[Bullous mycosis fungoides-clinical indicator for an aggressive course of disease].

Mycosis fungoides (MF) is defined as the most common cutaneous T‑cell lymphoma (CTCL). The bullous form is considered one of its numerous variants. Only a few cases of this rare entity have been described.

Poxvirus infections in dermatology - the neglected, the notable, and the notorious.

The family Poxviridae currently comprises 22 genera that infect vertebrates. Of these, members of the Ortho-, Para-, Mollusci- and Yatapoxvirus genera have been associated with human diseases of high clinical relevance in dermatology. Historically, smallpox had been a notorious health threat until it was declared eradicated by the World Health Organization in 1979.

S3 guideline "actinic keratosis and cutaneous squamous cell carcinoma" - update 2023, part 2: epidemiology and etiology, diagnostics, surgical and systemic treatment of cutaneous squamous cell carcinoma (cSCC), surveillance and prevention.

Actinic keratosis (AK) are common lesions in light-skinned individuals that can potentially progress to cutaneous squamous cell carcinoma (cSCC). Both conditions may be associated with significant morbidity and constitute a major disease burden, especially among the elderly. To establish an evidence-based framework for clinical decision making, the guideline "actinic keratosis and cutaneous squamous cell carcinoma" was updated and expanded by the topics cutaneous squamous cell carcinoma in situ (Bowen's disease) and actinic cheilitis.

Real-world outcomes using PD-1 antibodies and BRAF + MEK inhibitors for adjuvant melanoma treatment from 39 skin cancer centers in Germany, Austria and Switzerland.

Background: Programmed death-1 (PD-1) antibodies and BRAF + MEK inhibitors are widely used for adjuvant therapy of fully resected high-risk melanoma. Little is known about treatment efficacy outside of phase III trials. This real-world study reports on clinical outcomes of modern adjuvant melanoma treatment in specialized skin cancer centers in Germany, Austria and Switzerland.

Effects of the COVID-19 pandemic on care of melanoma patients in Berlin, Germany: the Mela-COVID survey.

Background: The COVID-19 pandemic imposes major challenges for care of cancer patients.

Objectives: Our aim was to assess the effects of the pandemic on treatment and appointments of patients with malignant melanoma based on a large skin cancer centre in Berlin, Germany, and identify reasons for, and impact factors associated with these changes.

Materials & Methods: Patients with melanoma treated from January 1st 2019 received a postal survey with questions on impairment due to the pandemic, fear of COVID-19, fear of melanoma, changes in therapy and/or appointments, including reasons for the changes.

Melanomversorgung während eines Jahres Pandemie in Berlin: abnehmende Terminstornierungen trotz zunehmender Besorgnis über COVID-19.

Hintergrund Und Ziele: Die COVID-19-Pandemie stellt für Krebspatienten eine große Herausforderung dar. Unser Ziel war es, ihren Einfluss auf die Behandlung und auf Arzttermine von Melanompatienten nach einem Jahr Pandemie zu untersuchen.

Patienten Und Methodik: Melanompatienten, die im Vivantes Hauttumorzentrum in Berlin behandelt wurden, beantworteten eine postalische Umfrage zu Pandemie-bedingten Änderungen ihrer Melanomversorgung.

Melanoma care during one year pandemic in Berlin: decreasing appointment cancellations despite increasing COVID-19 concern.

Background And Objectives: The COVID-19 pandemic poses a great challenge for cancer patients. Our aim was to assess its influence on treatment and appointments of melanoma patients after one year of pandemic.

Methods: Melanoma patients treated in the Vivantes Skin Cancer Centre in Berlin, Germany completed a postal survey on pandemic-related alterations in melanoma care.

S1-guideline atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS).

Atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS) are rare cutaneous neoplasms representing histomorphological, genetic as well as epigenetic variants of a disease spectrum. Both tumors typically manifest as nonspecific, often ulcerated, skin- to flesh-colored nodules in chronically sun-damaged skin of elderly male patients. AFX is a rather well demarcated, often rapidly growing tumor.

Occupational contact dermatitis in painters and varnishers: Data from the Information Network of Departments of Dermatology (IVDK), 2000 to 2019.

Introduction: Painters and varnishers ("painters") are exposed to various contact allergens and skin irritants, and therefore, are at risk for developing occupational dermatitis (OD).

Objective: To describe the spectrum of occupational sensitizations in painters and revise the corresponding current patch test recommendations.

Patients And Methods: Retrospective analysis of Information Network of Departments of Dermatology (IVDK) data from 2000 to 2019 with focus on male painters with OD, ages 20-59 years (n = 557) in comparison to age-matched male painters without OD (n = 422) and male OD patients who have had never worked as painters (n = 13 862).

Patient preferences for treatment of advanced melanoma: impact of comorbidities.

Background And Objectives: Choice of treatment for advanced melanoma is crucially influenced by comorbidities and patient preferences. Our study aimed to investigate the impact of comorbidities on preferences.

Patients And Methods: 150 patients with melanoma stage IIC-IV completed a discrete choice experiment to determine preferences for outcome (overall response rate [ORR], 2-year survival, progression-free survival [PFS], time to response [TTR], kind of adverse events [AE], AE-related treatment discontinuation) and process attributes (frequency and route of administration [RoA], frequency of consultations) of systemic melanoma treatments.

[Cutaneous squamous cell carcinoma].

Cutaneous squamous cell carcinoma (cSCC) is one of the most common cancers of the Caucasian population and accounts for 20% of all skin tumours. An S3 guideline of the German Guideline Program in Oncology has been available since 2019. The diagnosis is based on the clinical examination.
