1976年から1996年に岡山大学第2内科を受診したサルコイドーシス255例のうち,65例(71病変)の皮膚サルコイドーシス(皮膚サ症)について,臨床経過,臨床検査成績,胸部病変との関連,予後について検討した｡皮膚サ症患者の年齢は18歳から77歳で中央値は51歳であった｡女性例が42例(65%)と多
く,特に50歳代女性に43%と最も高率であった｡皮膚病型では結節型33例,皮下型16例,び慢浸潤型3例,局面型6例,結節性紅斑様皮疹3例,苔癬様型1例,瘢痕浸潤9例であった｡皮膚サ症では非皮膚サ症に比して気管支肺胞洗浄液中リンパ球の低率が見られたが,その他の臨床成績に差は認められなかった｡皮膚病型別に検討すると,局面型,び慢浸潤型では気管支肺胞洗浄液中リンパ球CD4/CD8比は高く,3年後の皮膚および肺病変の残存率は高かった｡一方皮下型ではCD4/CD8比は低く皮膚,肺病変の残存率も低かった｡Of 255 patients with clinical and histologic evidence of sarcoidosis, 65 (25percent) presented with various cutaneous manifestations of the disease. Cutaneous sarcoid patients were 42 women and 23 men ranging from 18 to 77 years in age. The skin lesions have included nodular infiltration in 33 patients, subcutaneous tumor in 16 patients, lupus pernio in 3, annual plaques in 6, erythema nodosum-like eruption in 3, lichinoid in 1, and scars in 9. There was no correlation between the presence of cutaneous lesions and chest radiolographic stages, abnormal pulmonary gallium uptake, cell differenciations of bronchoalveolar lavages and serum angiotensin converting enzyme activities. Forty-six patients followed for at least 3 years to determine the course of the disease. Subcutaneous tumors tended to heal within 3 years, while lupus pernio and plaque lesions were likely to have a protracted course
