We report the case of a 26‐year‐old man with acral tetany and muscular cramps of the upper limbs associated with hypocalcemia caused by hypoparathyroidism and celiac disease. Physical examination revealed a transverse leukonychia which disappeared after treatment with calcium lactogluconate, calcium carbonate and calcitriol. Hypocalcemia may induce nail alterations with a double mechanism represented by angiospasm and disorganization of the hard keratin and of the integrin subunits.
