title: [Efficacy of tonsillectomy on psoriasis and tonsil histology].
abstract: Treatment outcomes of tonsillectomy were studied in 7 Japanese patients with psoriasis--3 males and 4 females aged 9 to 46 years (median: 23 years)--followed up 2 to 9 years after tonsillectomy. All skin lesions disappeared in 3 patients, 80% of those in 2, and no change in the remaining 2 during follow-up. Of 5 in whom skin lesions improved, 4 were females and had a history of tonsillitis making skin lesions worse. In quantitative immunohistologic analysis on tonsillar tissues by CD20 and anti-ssDNA antibodies, areas of T cell-nodules were significantly expanded, but those of the B-lymphoid follicles were smaller, and the number of apoptotic cells increased in tonsils from patients with psoriasis and PPP compared to those with recurrent tonsillitis. The area of T cell-nodules and the number of apoptosis cells were significantly larger in tonsils from 4 patients with complete recovery after tonsillectomy compared to the remaining 9 without complete recovery. This suggests that histologic evaluation may be helpful in estimating the effectiveness of tonsillectomy.
