CUTANEOUS SARCOIDOSIS

Sarcoidosis is a multi-organ granulomatous disorder of unknown cause. Skin sarcoidosis occurs in about 25% of patients with systemic disease and may also arise in isolation. A wide range of clinical presentatio ns of cutaneous sarcoidosis is recognised. The diagnosis rests on the presence of non-caseating granulomas on skin biopsy and the exclusion of other granulomatous skin disease. The treatment and overall prognos is of cutaneous sarcoidosis is primarily dependent on the degree of sy stemic involvement. In patients with aggressive disease limited to the skin immunosuppressive therapy may be indicated.
