[Clinical aspects and characteristics of the course of most common nonpulmonary localizations of sarcoidosis].

The most extrapulmonary sites of the sarcoidosis erythema nodosum, such as peripheral lymph nodes, skin, subcutaneous fat, heart, liver, spleen, and kidney are described in the paper. During a follow-up of 502 patients with sarcoidosis in 1986-1993, the incidence of sarcoidosis of extrapulmonary site was 18.9%. Erythema nodosum is regarded as a nonspecific allergic syndrome. Sarcoidosis of extrapulmonary site is characterized by multiple involvements, suppressed T-cell immunity, recurrence, which requires adequate treatment and continuous monitoring.
