ABSTRACT
The Melanotic Neuroectodermal Tumor of Infancy (MNTI) is an asymptomatic, pigmented neoplasm characterized by a fast and locally aggressive growth along with a rare tissue formation. In the diagnostic process, the use of imaging exams can suggest a local destruction suggestive of malignancy, a sign of bone remodeling and expansion. Therefore, as any early diagnosis minimizes risks and improves the prognosis of treatment for the patient, the aim of this study was, based on a clinical case report, to corroborate the use of histopathological analysis associated with immunohistochemistry. Thus, we conclude that the immunohistochemical exam is of great importance for a better complementation of the MNTI diagnosis process. In addition, it can reveal signs of possible aggressive growth.
ABSTRACT
Introduction: Medication-related osteonecrosis of the jaw (MRONJ) occurs by the use of a drug that has osteonecrosis as one of its side effects. Case Report: We describe a case of a 48-year-old oncological patient who had brain and bone metastasis due to breast cancer and was medicated with bisphosphonates (BPs). She presented cavities, and after an incorrect exodontia, the lesion evolved into a jaw osteonecrosis. Then she did a sequestrectomy and was treated using laser therapy. Radiological and clinical features are also described. Conclusion: In a case like this, we notice how necessary is a complete evaluation of the oncological patient before some procedures and laser therapy as an effective ally in the management.
ABSTRACT
Imaging examinations play an important role in the diagnosis of sialolithiasis, whose symptoms are initially confounded with other diseases. The objective of the present case report is to highlight imaging and processing techniques as well as image analysis for the preoperative assessment and planning of surgical interventions and adequate treatment of massive sialoliths. A 35-year-old male patient presented complaining of pain in the submandibular region and purulent secretions from a lingual caruncle with slightly increased volume in the region. Imaging examinations were ordered as follows: cone beam computed tomography, ultrasonography, and three-dimensional reconstruction, including clinical evaluation. A final diagnosis of sialolithiasis was established. Surgery was indicated and carried out by using a lateral transcervical approach for complete resection of the gland, which was based on the calculation of the total volume of the sialolith, thus increasing the surgery's success.
