[Extrapulmonary manifestations of sarcoidosis as the cause of primary symptoms--4 case reports].

Sarcoidosis is a multisystem disorder most frequently presenting with hilar lymphadenopathy, pulmonary infiltrations, ocular and skin lesions. However pulmonary manifestations typically dominate, any organ can be affected. Sometimes leading symptoms are caused by extrapulmonary manifestation of the disease, and together with the absence of typical picture in chest radiographs may be confusing for the physicians. We present 4 cases of proven sarcoidosis in which leading symptoms were caused by sarcoidal involvement of different organs (liver, spleen, heart and skin) without typical changes in the lung. In all cases multiorgan involvement was documented and disease was successfully treated.
