To the Editor.—
Although the cause of psoriasis remains obscure, some factors are known to be able to trigger or aggravate the disease. Agents that can induce a generalized form of psoriasis include drugs, sunlight, and more rarely metabolic disorders such as hypocalcemia.1Adult-onset idiopathic hypoparathyroidism is an uncommon disease that appears with hypocalcemia,2 and whose association with the development of a generalized form of psoriasis has been only rarely reported.1 We present a patient who developed a generalized pustular psoriasis associated with severe hypocalcemia secondary to idiopathic hypoparathyroidism.
