Abstract: The coexistence of hypercalcemia with thyrotoxicosis is rare and easily misdiagnosed or mistreated due to the lack of clinical specificity.In this paper,we reported three cases of hypercalcemia caused by thyrotoxicosis from the Affiliated Hospital of Southwest Medical University,including their clinical manifestations,diagnosis and treatment,and conducted a literature review,through which we explored the causes,pathogenesis,essentials of diagnosis and treatment methods of hypercalcemia associated with thyrotoxicosis,in order to provide a basis for clinical disease treatments.
