In clinical practice, situations continuously occur in which medical professionals and family members are confronted with decisions on whether to extend or limit treatment for severely ill patients in end of life treatment decisions. In these situations, advance directives are helpful tools in decision making according to the wishes of the patient; however, not every patient has made an advance directive and in our experience medical staff as well as patients are often not familiar with these documents. The purpose of this article is therefore to explain the currently available documents (e.g. living will, healthcare power of attorney and care directive) and the possible (legal) applications and limitations in the routine clinical practice.

Skin manifestations of sarcoidosis occur in up to 30% of cases. This review summarizes and illustrates in detail the differences between specific and unspecific skin manifestations of sarcoidosis. Important differential diagnoses, such as tuberculosis, cutaneous lymphoma and syphilis have to be excluded. The indications for systemic treatment are primarily determined by the extent of organ involvement and also by the cosmetic impairment.

Ocular manifestation of sarcoidosis occurs in up to 60% of patients with confirmed systemic sarcoidosis and represents one of the most common forms of noninfectious uveitis. In known pulmonary sarcoidosis, ocular involvement can occur in up to 80% of cases. Sarcoidosis can also present only in the eye, without a systemic manifestation (ocular sarcoidosis). ⋯ For diagnosis, specific clinical signs involving the eye (bilateral granulomatous changes in all parts of the eye) and typical laboratory investigations (angiotensin-converting enzyme, ACE; lysozyme; soluble interleukin 2 receptor, sIL2R; chest X‑ray; chest CT) have to be taken into account, since biopsy to prove noncaseating granulomas is not performed with changes restricted to the eye due to the high risk of vision loss. Ocular sarcoidosis mostly responds well to local or systemic steroid treatment. If the therapeutic effect is insufficient, immunosuppressive agents and biologics can be applied.
