Introduction: Spinal tumors are rare in the pediatric population, presenting many specific peculiarities when compared to adults. We have performed a broad narrative review to describe the most common spinal tumors in children, discussing their main characteristics and management options. Method: The authors have performed an extensive review of the peer-reviewed literature addressing the aforementioned objectives. Results: Multimodality radiological studies (plain films, 3D computed tomography scan and magnetic resonance imaging) are necessary for proper evaluation and differential diagnosis of spinal tumors in children...

Cherubism is a rare autosomal dominant condition affecting the jaws and caused by mutations in the gene encoding for the adapter protein SH3BP2 that maps to chromosome 4p16.3. Cherubism is characterized by symmetrically developing bone lesions in the maxilla and mandible. The lesions have been radiographically and histopathologically well-described. Here, we present a family with cherubism with two of its members featuring odontogenic tumorous proliferations in association with persistent central giant cell lesions (CGCL)...

BACKGROUND: Giant cell tumor (GCT) of bone is a benign, though locally aggressive tumor, classically described as an eccentric lytic lesion, often with cortical expansion and destruction. It typically involves the metaphysis or epiphysis of long bones in skeletally mature patients, with a slight female predominance. The incidence in the small bones of the hand has been reported to be 2% to 5%. METHODS: Treatment options have evolved in recent years, and currently include intralesional curettage with or without adjuvant therapy, wide resection, and occasionally amputation...

Ameloblastic carcinoma (AC) is a rare malignant odontogenic tumor with poor prognosis. It has an aggressive clinical course with extensive local destruction. It occurs primarily in the mandible. It may clinically present as a cystic lesion with benign clinical feature or as a large mass with ulceration, significant bone resorption and mobility of teeth in the affected region. Reliable evidence of it's biological activity along with extensive local destruction, direct extension of tumor, lymph node involvement and metastasis to various sites (frequently lung) have been reported...

Osteochondroma is the most common benign bone tumor. Approximately 15% of osteochondromas occur as multiple lesions. Multiple osteochondromatosis has a higher risk of developing chondrosarcomas, which are of low grade with good prognosis. About 10% of all chondrosarcomas may undergo dedifferentiated change, which has a poorer prognosis. Dedifferentiated peripheral chondrosarcoma developing within an osteochondroma is extremely rare. Dedifferentiation usually occurs in the form of osteosarcoma, malignant fibrous histiocytoma, fibrosarcoma, or rhabdomyosarcoma...

OBJECTIVE: The best treatment of aneurysmal bone cyst (ABC) is still unclear. This study aimed to evaluate the usefulness of extended curettage and ethanol as an adjuvant to reduce local recurrence of ABCs. METHODS: Retrospectively, 68 cases treated for primary and secondary ABCs caused by benign tumors from 2003 to 2013 were enrolled to a follow-up visit between one to ten years after the surgery. The treatment protocol was en-bloc resection, biopsy and curettage, extended curettage consisted of curettage, high-speed burring, ethanol 96%, and electrocauterization (combined four-step alcohol-using approach) followed by defect filling, consecutively...

The osteoid osteoma is a benign primary bone tumor that affects mainly males in the second and third decades of life. Radiographic findings show a radiolucent nidus surrounded by reactive sclerotic bone, particularly in the long bones of the lower extremity. Clinically, it presents persistent pain, which is worse at night and improves with salicylates. It can be a self-limiting injury, with an average duration of three years, but because of pain intensity and intolerance to prolonged use of nonsteroidal anti-inflammatories, surgical treatment is an option...

Extraskeletal chondroma is defined as a rare, benign, cartilaginous tumor arising from soft tissues such as tendons, tendon sheath synovia, and joint capsules with no continuity to the periosteum or bone cortex. In histopathologic findings, the tumor exhibits many lobular structures and some parts similar to hyaline cartilage. Therefore, it is sometimes difficult to differentiate this tumor from low-grade chondrosarcoma because of their similar histopathologic findings. In order to prevent recurrence, it is necessary to remove the tumor as a whole, including the capsule, so as not to leave any remnants of the tumor...

Multiple osteochondromas (MO) is one of the most common benign bone tumors in humans with an autosomal dominant hereditary mode. MO is a genetic heterogeneity disease with variable number and size of osteochondromas, as well as changeable number and location of diseased bones. Mutations in Exostosin-1/Exostosin-2 (EXT1/EXT2) genes are the main molecular basis of MO. EXT1 and EXT2 genes encode exostosin 1 and exostosin 2, respectively, both of which are transmembrane glycosyltransferases that elongate the chains of heparin sulfate (HS) at HS proteoglycans (HSPGs)...

Osteoid osteoma is a common benign tumor that is typically found in young adults and children, usually in the long bones of the lower extremity. Radiofrequency ablation (RFA) under computed tomography guidance is the standard of care for symptomatic osteoid osteomas. However, patients with osteoid osteoma of the hand or foot are often treated with open surgery because of the risk of injury to vascular and neural structures from RFA. This risk is more pronounced in pediatric patients because of the small lesion size and proximity of lesions to important neurovascular structures...

OBJECTIVE Osteoblastoma is a rare primary benign bone tumor with a predilection for the spinal column. Although of benign origin, osteoblastomas tend to behave more aggressively clinically than other benign tumors. Because of the low incidence of osteoblastomas, evidence-based treatment guidelines and high-quality research are lacking, which has resulted in inconsistent treatment. The goal of this study was to determine whether application of the Enneking classification in the management of spinal osteoblastomas influences local recurrence and survival time...

Gangliocytic paraganglioma (GP) is a rare tumor of uncertain origin most often located in the second portion of the duodenum. It is composed of three cellular components: Epithelioid endocrine cells, spindle-like/sustentacular cells, and ganglion-like cells. While this tumor most often behaves in a benign manner, cases with metastasis are reported. We describe the case of a 62-year-old male with a periampullary GP with metastases to two regional lymph nodes who was successfully treated with pancreaticoduodenectomy...

Epidermal cysts are benign tumors derived from the epidermis or the epithelial hair follicle filled with keratin and lipid-rich debris, typically occurring in areas with a high-density of sebaceous glands. These cysts commonly occur on the face, scalp, neck and trunk, where the sebaceous glands are more active. Their localization within the bone is extremely uncommon. The current study details the case of a 24-year-old male who presented with right otorrhea and ipsilateral hypoacusia having undergone right overlay myringoplasty for subtotal eardrum perforation...

Osteoid osteoma is a common benign bone tumor of unknown etiology affecting the young adult with characteristic clinical and radiographic presentation in its common locations. However, when it arises in unusual intra-articular locations diagnosis may be misleading, often mimicking other entities leading to delayed management. We present a case series of three cases with intra-articular osteoid osteoma that were diagnosed with the help of correlative imaging.

BACKGROUND: The burden of managing patients with musculoskeletal neoplasms in the West African sub-region is quite significant. This is largely due to late presentation, delay in making diagnosis, and failure of obtaining consent to certain surgical procedures. Improvements in diagnosis and treatment over the years have however increased life and limb survival for many patients. This study was aimed at evaluating the clinicopathologic pattern of neoplasm as it affects the upper and lower limbs with a view to determining the most common types, the most involved sites of the body and the age at presentation of these tumors...

Osteosarcoma is the most frequent primary bone tumor that affects adolescents and children. However, diagnostic and prognostic biomarkers for osteosarcoma remain lacking. (Tim-3) T-cell immunoglobulin domain and mucin domain-3, which negatively regulates T cell helper (Th1) cells and affects cytokine expression, has attracted increasing attention due to its critical role in regulating both adaptive and innate immune cells. In this study, we evaluated serum soluble Tim-3 level in osteosarcoma patients to explore its diagnostic and prognostic value for this particular malignancy...

Sarcomas are a heterogeneous group of rare tumors and arise either from soft tissue or from bone. Soft-tissue sarcomas (STSs) initially metastasize to the lungs. Metastases to extrapulmonary sites such as liver, brain, and soft tissue distant from primary tumor usually develop later. However, cases with isolated adrenal metastasis without disseminated disease have been reported in literature. We present a case of primary myxoid liposarcoma of the lower limb, in which staging (18)-F fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) scan detected a suspicious FDG avid adrenal lesion which eventually on resection was diagnosed as asymptomatic pheochromocytoma...

Stafne bone cavity (SBC) is an uncommon lesion of the mandible; and generally found incidentally on routine radiographic examinations. The radiographic differential diagnosis of SBC includes a variety of lesions including odontogenic cysts, benign tumors, or bone metastases. In the present case, a 22-year female patient was admitted with chief complaint of pain in the right mandibular molar area. On panoramic radiographic examination, a non-specific large radiolucent lesion related to mandibular molar teeth was detected and extra-oral surgical intervention was planned...
