The Solitary Bone Plasmacytoma (SBP) is a rare oncologic disease corresponding to less than 5% of the malignant neoplasms of the plasma cells. It is characterized as a localized aggressive tumor consequent to the accumulation of monoclonal plasma cell neoplasms and, due to the rarity of the disease, there are only few clinical studies reporting it especially regarding prognostic factors and treatment. Here, we report a fatal clinical case of SPB in Roraima, the northernmost state of Brazil. The study shows a case of solitary bone plasmacytoma on the femur, where the patient was submitted to the preconized radiotherapy cycles. However, over approximately four-years following the diagnose, the patient required multi-modal approach to guarantee quality of life during the survival time. Finally, this study explores SBP-related issues and examines the challenges physicians face when managing the care of patients with SBP.
