Myelodysplastic syndrome, osteoporosis and medication-related osteonecrosis of the jaw: a case report

Abstract

Medication-related osteonecrosis of the jaw is a frequent collateral effect found in patients under antiresorptive treatments. Malignancies such as multiple myeloma, breast and prostate cancer as well as bone-metabolic disorders such as osteoporosis, lead the indications for these antiresorptive therapies. Even with a low frequency, myelodysplastic syndromes are also entities that have previously been associated with the development of jaw osteonecrosis. the aim of this study is to present a case of a 78-year-old male patient with myelodysplastic syndrome and secondary osteoporosis, treated with high-dose Zoledronic Acid and who developed a clinical scenario compatible with medication-related osteonecrosis of the jaw during its evolution. : the case was recorded and treated in the Oral Medicine Department, Facultad de Odontología, Universidad Nacional de Córdoba, during a two-years period with a partial resolution, which recurred fourteen months later, where finally therapeutic success was achieved through a conservative management. Due to the increasingly use of antiresorptive drugs, the development of jaw osteonecrosis is possible associated with less frequent pathologies, such as myelodysplastic syndrome. Treatment success in these patients depends on interdisciplinary management and a rigorous clinical, medical and dental follow-up.
