Tehran University of Medical Sciences Acta Medica Iranica 0044-6025 42 4 2004 08 15 300 302 Sh.S.Ashkevari A.Maboodi 2015 09 28 Generalized pustular psoriasis with hypoparathyroidism has been reported previously often as a post thyroidectomy syndrome with hypoalbuminemia and hypocalcemia. But reports on association of pustular psoriasis with idiopathic hypoparathyroidism are very rare, and almost all of them occurred in patients with known psoriasis vulgaris. We report one of the youngest cases of this association in a 17 year old girl without previous history of psoriasis which her eruption disappeared completely after the correction of hypocalcemia and remained free of eruptions until 6 months afterward. This case adds further evidence to the importance of calcium in the pathogenesis of at least some forms of psoriasis. https://acta.tums.ac.ir/index.php/acta/article/view/2740 https://acta.tums.ac.ir/index.php/acta/article/download/2740/2722
