Giant cell tumor of bone (GCTB) is mostly a benign tumor, but associated with recurrences and metastasis. Lately, denosumab is being utilized in the treatment of certain GCTBs. Twenty-seven tumors, analyzed in the present study, occurred in 16 males and 11 females (M: F = 1.45:1), in the age-range of 16 to 47 years (mean = 29.5, median = 29). Most tumors were identified in the tibia(6) and femur(6), followed by the humerus(3), radius(3), pelvis(3), fibula(3), sacrum(1), metacarpal(1) and metatarsal(1) bones...

Extragonadal teratomas are rarely encountered in infants and children. These tumors are reported in retroperitoneum, floor of the mouth, mediastinum, craniofacial region or even in the solid organs of the body. Most of the gluteal teratomas reported in the literature are in fact, lateralized sacrococcygeal teratomas. We are reporting a case of unilateral big gluteal teratoma in a 6-year-old girl. The tumor did not have any connection with the sacrum or coccyx and was successfully removed. Histology showed well-differentiated bowel as well as fetiform structures...

Neurofibrosarcoma is rare in the pediatric age group. A malignant tumor of the sacrum presents significant challenges, especially if the goals are to resect with wide and clean surgical margins and to achieve acceptable functional outcomes. The authors report a case of this rare tumor affecting the sacrum and sacral nerve roots of a 7-year-old girl and review the role of total hemisacrectomy sparing the contralateral sacral nerve roots and lumbopelvic reconstruction in the treatment of this disease. This patient is, to the best of the authors' knowledge, the youngest to be treated in this manner...

Osteoblastoma (OB) is an uncommon benign bone-forming tumor accounting for <1% of all bone neoplasms. Unlike conventional OB, its small subset variant "Epithelioid osteoblastoma (EO)" is characterized by its propensity for local invasion and recurrent behavior. This rare variant of an uncommon tumor when occurs in an atypical site can lead to diagnostic problems more so due to ambiguous clinico-radiologic presentation. This was what faced in the present case of 18-year-old female with a swelling in upper jaw...

BACKGROUND: The Response Evaluation Criteria in Solid Tumors (RECIST) are the current standard for evaluating disease progression or therapy response in patients with solid tumors. RECIST 1.1 calls for axial, longest-diameter (or perpendicular short axis of lymph nodes) measurements of a maximum of five tumors, which limits clinicians' ability to adequately measure disease burden, especially in patients with irregularly shaped tumors. This is especially problematic in chordoma, a disease for which RECIST does not always adequately capture disease burden because chordoma tumors are typically irregularly shaped and slow-growing...

Perirectal epidermoid cysts are congenital cysts originating from the ectodermal germ cell layer of the hind gut. Their presenting symptoms are most often nonspecific and distinguishing them from other presacral developmental cysts often present a diagnostic and therapeutic dilemma. We present a 58-year-old woman who presented with chronic dyschezia and hematochezia of a few days duration and no prior colonoscopies. Initial blood work and tumor markers were unremarkable. Pelvic magnetic resonance imaging (MRI) showed a 7...

Hibernoma is an uncommon lipomatous tumor composed of brown adipose cells that until recently has only ever been described in soft tissue locations. This report describes the histological features of a discrete lesion in the sacrum of an 84-year-old lady. Biopsy of this lesion demonstrated that it consisted predominantly of multivacuolated lipocytes with a morphological and immunohistochemical profile consistent with brown fat cells. The lesion was diagnosed as an intraosseous hibernoma. This is the 16th report in the English literature of a hibernoma occurring outside of a soft tissue location...

Clear-cell chondrosarcoma is a rare, low-grade variant of chondrosarcoma characterized by slow growth, low metastatic potential, and a predilection for local recurrence long after treatment. We report an unusually aggressive case of clear-cell chondrosarcoma of the humerus with early metastasis to multiple bony sites including femur, thoracic and lumbar spine, sacrum, and iliac bone. Our purpose is to alert physicians to the sarcoma's potential for aggressive behavior, necessitating closer and more frequent followups for early detection and treatment of tumor recurrence and metastasis...

INTRODUCTION: Giant cell tumor is the most common benign lesion encountered. It accounts for 5 % of all skeletal tumors. It mainly affects the epiphysis of long bones and rarely axial bones. In axial bones, sacrum is the most common site to be affected. CASE REPORT: A 23 year old female with giant cell tumor of sacrum was treated initially with conservative treatment (serial angioembolisation and bisphosphonates). Later intralesional curettage was done as the patient started developing bladder and bowel disturbances after two sessions of angioembolisation...

BACKGROUND: Chondromyxoid fibroma (CMF) is an extremely rare, benign cartilaginous tumor that makes up <0.5% of all bone tumors, typically presenting in the second or third decade of life. CMF of the sacrum is exceedingly rare, with only seven documented cases reported in the neurosurgical literature. CASE DESCRIPTION: We report a case of a 35-year-old female with a 3 month history of lower back pain after sustaining a fall on her sacrum/coccyx presenting with a progressive complaint of localized lower back pain, occasional urinary retention without incontinence, gluteal hypesthesia, and pressure below the gluteal crease...

BACKGROUND: The ability of T-cells to traffic to and penetrate tumors impacts the clinical efficacy of T-cell therapy therefore methods to track transferred T-cells in vivo are needed. In this preliminary report, we evaluated the use of concurrent SPECT/PET-CT imaging to monitor the egress of HER-2/neu specific T-cells in a breast cancer patient with extensive bone-only metastatic disease. FINDINGS: Indium (In-111) labeled T-cells demonstrated similar or greater viability than unlabeled T-cells at either a low or high dose of In-111 over a 24-h incubation period in vitro...

Intraosseous schwannoma is a rare benign bone tumor that originates from Schwann cells of the nerve sheath. The majority of intraosseous schwannomas arise in the mandible and sacrum, but an intraosseous schwannoma involving the ulna is described in the present case report. Radiologically, the current case presented as a well-defined lytic lesion, with a pathological fracture and no intralesional calcification, in the proximal metaphysis of the left ulna. Using magnetic resonance imaging, an intraosseous mass spreading out from the cortical defect was observed...

STUDY DESIGN: This is a retrospective, diagnostic study, level IV. BACKGROUND: It appears to be necessary to identify prognostic markers for individual risk estimation for progression and survival in patients with chordoma, a rare disease. Are pre-operative serum levels of C-reactive protein (CRP) associated with disease progression and survival? METHODS: Survival rates of 24 patients (18 males, 6 females) (mean age 67 years (SD ± 16; range 20-85 years); minimum follow-up 2 years, mean follow-up 5 years (SD ± 5; range 2-19 years)) with chordoma of the lower spine and sacrum were assessed with a focus on pre-operative CRP levels...

Chordomas are rare malignant tumors that develop from embryonic remnants of the notochord and arise only in the midline from the clivus to the sacrum. Surgery followed by radiotherapy is the standard treatment. As chordomas are resistant to standard chemotherapy, further treatment options are urgently needed. We describe the establishment of a clivus chordoma cell line, MUG-CC1. The cell line is characterized according to its morphology, immunohistochemistry, and growth kinetics. During establishment, cell culture supernatants were collected, and the growth factors HGF, SDF-1, FGF2, and PDGF analyzed using xMAP(®) technology...

Sacral insufficiency fracture resulting from a metastatic tumor or an osteoporotic fracture causes severe low back pain and radiating pain mass effect on neural foramen and chemical irritants. Percutaneous sacroplasty is one of the effective treatment modalities for sacral insufficiency fracture and its pain. Because of the structural complexity of the sacrum, obtaining an epidurogram of the S1 and S2 nerve roots before the start of the procedure can be helpful to avoid nerve injury. We present 2 successful cases of percutaneous sacroplasty performed under fluoroscopic guidance...
