Pityriasis rubra pilaris (PRP) includes a spectrum of rare chronic inflammatory disorders with papulosquamous eruptions of unknown cause. Different etiologies have been proposed such as vitamin A metabolism dysfunction, association with autoimmune disorders, infection or malignancies. However, PRP seems to be a polygenic skin disorder. Classical systemic treatment is empirical and includes retinoids and methotrexate; however, only few series on treatments exist. Recently there has been an increasing number of reports documenting that new biologicals and in particular TNF-α blockers are safe and effective.

Invasive malignant melanoma is the most common fatal form of skin cancer. Fluorine-18-fluorodeoxyglucose positron emission tomography-computed tomography demonstrates a very high sensitivity and specificity for the detection of melanoma metastases. Here, we report an unusual case of toxoplasma lymphadenitis in a male adult patient mimicking a malignant cervical lymphadenopathy. Toxoplasmosis is a zoonosis caused by the intracellular parasite Toxoplasma gondii, which is usually asymptomatic in immunocompetent hosts.

Dehydrated human amnion/chorion membrane allograft (dHACM) derived from placenta is increasingly used for skin and soft tissue repair in several medical specialties. Promising effects of dHACM were also reported in chronic venous and diabetic leg ulcers. However, dHACM is cost‐intensive and its effect on chronic leg ulcers of other etiologies and pain reduction is unknown. Clinical predictors of a favorable response to dHACM during the early treatment period could help to limit unnecessary costs. In our case series with six patients suffering from chronic lower leg ulcers of various etiology, the effect of dHACM once per week on reduction of pain and wound size during a 5‐week period was examined. dHACM resulted in effective pain reduction and improved wound healing in three patients with chronic leg ulcers due to calciphylaxis, chronic venous disease and reactive angioendotheliomatosis. Pain reduction after 1 to 2 applications of dHACM predicted a favorable healing response. Hence, our observation indicates that assessment of pain 3 weeks after initiation of dHACM may be a clinical predictor to justify dis‐/continuation of dHACM and thereby may help to limit costs.

We herein report on an 80-year old male patient with a history of muscle weakness, fatigue and weight loss since several months. Because of a pathologic synacthen test in combination with decreased levels of ACTH, we diagnosed a secondary chronic adrenal insufficiency. Because of a normochromic, normocytic, and hypo-proliferative anemia, bone marrow puncture was performed, showing an anemia of chronic disease. We initiated hydrocortisone and anemia and patients' symptoms were fully reconstituted.
