Bilateral femur fracture as the first manifestation of multiple myeloma: a case report.

The authors aimed to elaborate on an interesting clinical case of a subject that came to our attention following a low-energy traumatic event, producing a bilateral femur fracture. During the instrumental investigations, findings pointing to multiple myeloma were described, in fact later confirmed by the histological and biochemical investigations. In this specific case, unlike manifestations in most patients with MM, the classic correlated pathognomonic symptoms, such as lower back pain, weight loss, recurrent infections, asthenia, were not present. Furthermore, the inflammatory indices, the values of serum calcium, renal function and hemoglobin were completely normal, although numerous bone localizations of disease already coexisted, and these were all unknown to the patient.
