Abstract
Gorham-Stout syndrome is a disease that presents idiopathic osteolysis of a bone or closely contiguous area. The etiology is unknown. It is a rare condition that is difficult to diagnose, and its treatment is controversial. It affects individuals irrespective of age or sex. In this study, we conducted a bibliographic review of the disease, specifically focusing on the differential diagnosis, and we demonstrated the follow-up on a patient with this syndrome from the time of its diagnosis, through treatment, to its current state of evolution.
