[Human monkeypox (Mpox)].

Until recently, human monkeypox (Mpox) were rarely observed outside of Africa, where the Mpox virus (MPXV) is endemic in some regions. In early May 2022, a global Mpox outbreak occurred. Crucial to this outbreak was human-to-human transmission during sexual activity.

[Exanthema after travel abroad].

In view of globalization and the associated transport of goods as well as rising travel activity, imported infections with subtropical and tropical pathogens are increasing in Germany. In returning travelers presenting with fever, general symptoms and skin rash, a number of diseases need to be considered. The clinical appearance of the skin rash, accurate travel history and epidemiological information on country-specific risks are helpful in making the correct diagnosis.

A case of linear porokeratosis superimposed on disseminated superficial actinic porokeratosis.

We present a female patient with linear porokeratosis of her right arm since childhood. At the age of 67 years she additionally developed disseminated superficial actinic porokeratosis (DSAP) involving both lower legs. This uncommon coexistence of two different types of porokeratosis fulfils the clinical criteria of a type 2 segmental manifestation of an autosomal dominant skin disorder, being superimposed on the ordinary nonsegmental lesions and reflecting loss of heterozygosity that occurred at an early developmental stage.

Liposomal pegylated doxorubicin versus low-dose recombinant interferon Alfa-2a in the treatment of advanced classic Kaposi's sarcoma; retrospective analysis of three German centers.

Background: Classic Kaposi's sarcoma (KS) is a rare neoplasm, predominantly occurring in older subjects of Eastern Europe or Mediterranean descent. While single lesions may be treated by simple excision, laser therapy, cryotherapy, or intralesional therapy, advanced or disseminated disease requires systemic treatment. Several studies reported the effectiveness of pegylated liposomal doxorubicin (PLD) and low-dose recombinant interferon alfa-2a (IFNalpha) in the treatment of AIDS-associated KS.
