Genitourinary tumors account for half of all documented cases of pseudohyperparathyroidism. The treatment of hypercalcemia is directed toward immediate correction of the electrolyte imbalance and long-term control. These goals are accomplished with volume repletion, calcium normalization and removal of the tumor. Effective therapy includes saline infusion and furosemide. Additional control is obtained with phosphates and/or indomethachin. In refractory cases actinomycin-D or mithramycin is helpful. The first reported case of urethral cancer and second reported case of testicular seminoma producing this syndrome are added to the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
