An Asymptomatic Bone Tumor Case Presenting with Elevated Acute Phase Reactant and Weight Loss Complaints

Asymptomatic Bone Tumor Case

Abstract

Atypical cartilaginous tumor (ACT) is a slow-growing tumor. Patients mostly present with complaints of pain, but lesions can sometimes be detected incidentally. High acute phase reactant (AFR) is a laboratory finding seen in the course of many diseases with chronic inflammation. In our case, the diagnosis phase of a patient who presented with high AFR and weight loss is described. The patient was investigated in detail for infection, rheumatic diseases, and malignancies. After positron emission tomography (PET-CT) and magnetic resonance imaging (MRI), ACT was diagnosed with a biopsy from the humerus region, which had no complaints. In this case report, it is emphasized how detailed and meticulously AFR elevation should be examined and that unexpected pathologies may occur under AFR elevation, and the diagnostic stages are explained in detail.
