A 67-year-old man presented with a maculopapular exanthem which started over the major joints. Within a few days, it spread to the entire skin surface and was accompanied by blisters as well as changes of the oral mucosa. ⋯ Targeted laboratory examinations detected serum antibodies against the epidermal basement membrane and autoantibodies against type VII collagen. The findings supported the diagnosis of a generalized inflammatory epidermolysis bullosa acquisita with mucosal involvement.

A 71-year-old man presented with giant basal cell carcinoma on the abdomen which had metastasized. He was treated with oral vismodegib. ⋯ Vismodegib was well tolerated without significant side effects. The tumor recurred promptly after vismodegib was discontinued, and then was resistant to therapy when vismodegib was re-administered.

Infectious diseases of the skin have become rarer in industrialized nations, but they still affect a considerable part of the population in tropical regions. Skin diseases induced by protozoa, worms and ectoparasites are among the 17 "neglected tropical diseases" defined by the WHO (leishmaniasis, dracunculiasis, lymphatic filariasis, onchocerciasis). ⋯ Among the 12 most frequent skin diseases in travellers are cutaneous larva migrans, leishmaniasis and myiasis. In this review, diagnosis, treatment and prevention of some the most relevant tropical dermatoses due to protozoa, worms and ectoparasites are discussed.

Jellyfish are distributed worldwide; they cause local skin injuries upon contact which are often followed by systemic signs of envenoming. ⋯ Among the injuries and envenoming symptoms caused by marine organisms, jellyfish dermatitis should not be underestimated. Skin reactions may not only a dermatological problem, but also be accompanied by complex systemic toxic symptoms which are a challenge for internists.

The use of hyaluronic acid fillers for treatment of rhytides (wrinkles) is widespread in aesthetic dermatology and is considered a safe procedure; however, complications can occur especially if the injections are carried out by an inexperienced person and/or with a lack of anatomical knowledge. The two cases presented here exemplify this problem. ⋯ While the patients in these two cases recovered completely, the injection of filler substances can also lead to the risk of potentially permanent side effects, such as granuloma, necrosis with scar tissue formation and even blindness. The frequency and severity of complications often show a direct correlation with the qualification or expertise of the person treating and hence injection treatments should be performed solely by physicians.
