Polygenic Score: A Tool for Evaluating the Genetic Background of Sporadic Hidradenitis Suppurativa.

Sporadic Hidradenitis Suppurativa (spHS) is a multifactorial disease in which genetic predisposition is intertwined with environmental factors. Due to the still to date limited knowledge of spHS genetics, we calculated Polygenic scores (PGS) to study the genetic underpinnings that contribute to spHS within European demographic. 256 spHS patients and 1686 healthy controls were analyzed across 6 European clinical centers.

The spectrum of melanocytic nevi and their clinical implications.

The magnitude of the topic of melanocytic nevi (MN) is directly related to its relevance in everyday clinical work. The different MN have different prognostic significance in regard to comorbidity and possible risk of transformation. In addition to the criteria of the ABCDE rule, relevant criteria in the assessment of an MN are the time of occurrence, the growth tendency, the distribution and the comparison with other MN of the respective individual.

Known and new facts on basal cell carcinoma.

Basal cell carcinoma (BCC) is the most common malignant tumor in light-skinned people and amounts to about 75 % of all cases of skin cancer. Increasing incidence rates have been reported for decades all over the world. The main risk factors include UV radiation, male sex, light skin type, advanced age, long-term immunosuppression, a positive individual or family history, and certain genodermatoses.

[Apremilast in the treatment of palmoplantar pustulosis : A case series].

This is a case series of 8 patients with palmoplantar pustulosis. These patients were treated with the phosphodiesterase‑4 inhibitor apremilast at our psoriasis outpatient clinic at the dermatological department of the University Hospital Innsbruck and we compared and documented the clinical response using an Investigator's Global Assessment (IGA) score over several months. This disease is characterized by its strong negative impact on the quality of life in affected patients, and by its resistance to therapy and its high relapse rate.

Pseudoprogression with subsequent complete response and severe thrombocytopenia to checkpoint inhibitor immunotherapy in a patient with advanced mucosal melanoma of the sinonasal cavity.

In this case report, we describe a patient with an inoperable mucosal melanoma of the sinonasal cavity who achieved an ongoing complete response to combined immunotherapy with ipilimumab and nivolumab after initial pseudoprogression. Despite massive enlargement of the tumor 9 weeks after treatment initiation, we decided to continue with checkpoint inhibitor immunotherapy because of lacking potent therapeutic alternatives and the possibility of pseudoprogression. In the computed tomography scan 3 months later, the tumor was no longer detectable.
