“…Sometimes forgotten results of sun exposure in patients with sarcoidosis (a disease which can be diffi cult to distinguish from tuberculosis) are hypercalcaemia , acute pancreatitis ,and soft tissue calcifi cation, and physicians advise patients with sarcoidosis to avoid sunlight or excessive exposure to sunlight. 4,5,6 The sanatorium regime per se does seem a thing of the past from the point of view of disruption of patients' personal, working or student lives, as well as the issue of building and staffi ng such units, which would be best sited as part of multidisciplinary hospitals. However the use of sunbeds as adjunctive therapy to the chemotherapy regime may be a more convenient and much less expensive option.…”

“…Dabei sollen mononukleäre Phagozyten aus Alveolen und befallenen Lymphknoten inaktives 25-Hydroxy-Vitamin D 3 rein substratabhängig mittels erhöhter 1␣-Hydroxylase-Aktivität in aktives 1,25-Dihydroxy-Vitamin D 3 umwandeln, und zwar besonders, wenn vermehrt Vitamin-D-Vorstufen vorliegen [1,4,12,13]. Wahrscheinlich spielt dieser Zusammenhang im hier vorgestellten Fall eine bedeutende Rolle: Der Patient erkrankte bei zuvor asymptomatischem Verlauf der Sarkoidose im Urlaub, wo er stark ultraviolettem Licht ausgesetzt war, so daß vermehrt Vitamin-D-Vorstufen vorlagen.…”

“…Der Grund für die Progredienz der Sarkoidose vom asymptomatischen Stadium I zum symptomatischen Stadium II bleibt offen, die extensive Sonnenexposition mit Hyperkalzämie erscheint ursäch-lich eher unwahrscheinlich. Ähnliche Fälle einer Hyperkalzämie bei Sarkoidose durch den Einfluss einer starken Sonnenbestrahlung sind in Fallberichten vereinzelt beschrieben [4,10]. Insofern unterstützt dieser Fall die Empfehlung, bei Sarkoidose einschließlich dieser Therapie sanken die Konzentrationen des Serumkalziums in den unteren Normbereich und die des Kreatinins auf 1,6 mg/dl bei Entlassung.…”
