(2019) Abril Cordero, Luz Marina; Cazar Almache, Marcelo Enrique; Espinoza Soto, Pedro Esteban; Palacios Vivar, Diego Esteban; Cañar Rivera, Gabriela Elizabeth
Introduction: Brown tumor is a rare pathology resulting from uncontrolled hyperparathyroidism, which produces areas of localized bone destruction. They are present at the facial level in the mandible and maxilla, ribs, clavicle, pelvic waist and upper and lower extremities. Its name is given by the pigmentation of the extravasation of blood and hemosiderin to the tumor. It can manifest itself in any decade of life. Has greater predisposition in women of the fourth and fifth decade of life. Its presence at the level of maxillary bones requires a complex system of studies and multidisciplinary management for diagnostic confirmation and treatment. Clinical case: The case of a 36 year old patient with no personal or family history is reported. She comes by referral for placement of a bone graft for dental mobility. In the image evaluation, there is a right radiolucent zone in the body of the mandible, in relation to the teeth. The lesion usually presents as a well-delimited unilateral or multilocular radiolucent area; another important radiographic finding in hyperparathyroidism is the absence of hard laminae around the dental organs. Conclusions: The brown tumor should be considered as a differential diagnosis of mandibular tumors due to the fact that not every tumor has a primary etiology
