[Sarcoidal allergic contact dermatitis due to palladium following ear piercing]. / Sarkoidale allergische Kontaktdermatitis auf Palladium nach Ohrpiercing.

Granulomatous tissue reactions due to jewelry made of gold, silver, nickel and palladium are rare but nevertheless have been known for a long time. A female patient developed nodular infiltrates after having been pierced with ear stickers containing palladium. A contact allergic reaction could be demonstrated as the underlying cause by inducing similar histological changes following patch testing with palladium.

[Sporotrichosis as the cause of a leg ulcer]. / Sporotrichose als Ursache eines Ulcus cruris.

A young man presented at Lugala Lutheran Hospital (Tanzania) with an ulcer on his lower leg which had developed over the past 9 weeks. Subcutaneous nodules and plaques were found all the way up to his groin; this observation prompted a strong suspicion that the patient had the lymphocutaneous form of sporotrichosis which had not been seen at this hospital before. The diagnosis was confirmed histopathologically. The patient was then treated with saturated solution of potassium iodide.
