Malignant transformation in fibrous dysplasia (FD) is uncommon. The purpose of
this study was to investigate clinical and imaging features, and outcomes of
malignant transformation in monostotic FD.Data for 10 pathologically confirmed
malignant transformations in monostotic FD from January 2005 to December 2013
were retrospectively reviewed. Patient data were recorded, and radiographs
(n?=?10), computed tomography (CT) (n?=?5), magnetic resonance (MR) (n?=?4), and
bone scintigrams (n?=?10) were evaluated for lesion location, margin, cortical
destruction, marrow involvement, periosteal reaction, and soft tissue mass by 2
musculoskeletal radiologists with agreement by consensus. Clinical features,
management, and prognosis were also analyzed for each of the 10 cases.There were
8 male and 2 female patients (mean age 46.5?±?15.9 years). The affected sites
were the femur (n?=?4), humerus (n?=?2), tibia (n?=?3), and ilium (n?=?1). Five
cases had received previous surgery and 5 cases had no history of surgery. No
patients had been given prior irradiation treatment. For the 5 cases with
surgery, radiographs and CT showed purely osteolytic lesions with poor
margination in the curettage area (n?=?5), cortical destruction (n?=?5), obvious
soft tissue mass (n?=?1), and mineralization (n?=?2). For the 5 cases without
surgery, radiographs and CT identified poorly marginated, osteolytic lesions
within or near the area with "ground-glass" opacity (n?=?4), cortical erosion
(n?=?4), and mineralization (n?=?2). Magnetic resonance imaging (MRI) also
identified lesions with heterogeneous signal intensity and pronounced
enhancement. Bone scintigraphy revealed eccentric increased uptake of
radionuclide in monostotic lesion (n?=?10). Pathology reports revealed
osteosarcoma (n?=?7), fibrosarcoma (n?=?2), and malignant fibrous histiocytoma
(MFH) (n?=?1). At the end of the study, 1 patient died from tumors, 1 patient was
alive with lung metastasis, 1 patient experienced recurrence, and 7 patients were
alive without recurrence.Patients with FD and a history of surgery should be
followed up, for the osteolytic lesions in the operative areas strongly indicate
the malignant transformation. The radiographic feature of FD-related malignancies
is poorly marginated, mineralized, and osteolytic lesions with cortical
destruction. Further investigations are needed to explore the pathogenesis of
malignancies in FD and to establish optimal therapeutic strategies.
