Primary neoplasms of the patella account for less than 1% of all primary bone tumors of the lower extremity, the most frequent of them being the giant cell tumor of bone, the chondroblastoma, and the aneurysmal bone cyst. Herein, we report the case of a 29-year-old woman with an active giant cell tumor of the patella (GCTP) with its clinical and radiological features and a brief review of the literature.

Small supernumerary ring chromosome 6 (sSRC[6]) is a rare chromosomal abnormality characterized by a broad clinical phenotype. The spectrum of this disorder can range from phenotypically normal to severe developmental delay and congenital anomalies. We describe two unrelated patients with small SRCs derived from chromosome 6 with a novel bone phenotype. Both patients presented with a complex bone disorder characterized by severe osteopenia, pathologic fractures, and cyst-like lesions within the bone. Imaging revealed decreased bone mineral density, mutiple multiloculated cysts and cortical thinning...

Ossifying fibroma (OF) is a benign fibro-osseous lesion mainly occurring in young adults and seems to originate from the periodontal ligament. Aneurysmal bone cyst (ABC) is a benign intraosseous lesion characterized by blood-filled spaces of various sizes. These two lesions can specifically affect the jaws and are commonly described in the literature. However, few cases describing an association of OF and ABC have been reported in the literature, especially in the maxillary sinus. We report the case of a 40-year-old male patient affected with an asymptomatic lesion with a dual component of OF and ABC laying in the maxillary sinus...

Aneurysmal bone cyst (ABC), a locally benign aggressive lytic lesion of either primary or secondary origin, seldom involves the talus. Herein, we present a 25-year-old man with recurrent ABC of the talus after curettage and bone grafting, which was managed by total resection followed by filling the defect using fibular graft and finally tibiotalocalcaneal arthrodesis due to articular surface involvement. At 18 mo postoperatively, no recurrence was detected. Arthrodesis might be a good option in cases with recurrent ABC of the talus especially with articular surface involvement...

Aneurysmal bone cyst is a benign tumor that can affect all bones in the body. It rarely affects the base of the skull. It is usually located at the level of the long bones. We report the clinical case of a 44-year old man treated for a mass in the basisphenoid wrongly diagnosed as invasive prolactin-producing macroadenoma for which he was put under dopamine agonists over a period of 9 months. We adjusted the diagnosis by suggesting aneurysmal bone cyst in the sphenoid bone on the basis of its almost pathognomonic radiological aspect on MRI...

BACKGROUND AND AIMS: Aneurysmal bone cysts represent about 1% of primary bone tumors. The standard treatment is curettage, followed by local adjuvant treatments and bone grafting. The problem is the high recurrence rate. The purpose of this study was to evaluate retrospectively the use of bioactive glass as a filling material in the treatment of aneurysmatic bone cysts in children. MATERIAL AND METHODS: A total of 18 consecutive children (mean 11.3 years at surgery; 10 males; 11 lower, 6 upper limb, 1 pelvis; 15 with primary surgery) with histologically proven primary aneurysmal bone cysts operated with curettage and bioactive glass filling between 2008 and 2013 were evaluated after a mean follow-up of 2...

PURPOSE: Aneurysmal bone cysts of the lumbar spine are usually treated by curettage followed by bone or bioactive ceramics grafting. Here, we present the first case of an aneurysmal bone cyst of the lumbar spine treated by percutaneous endoscopic lumbar discectomy (PELD). METHODS: We describe the clinical characteristics of the patient including the radiological and pathological findings of the tumor and the surgical technique used. RESULTS: A 15-year-old boy presented with low back pain, and he was diagnosed with an aneurysmal bone cyst of the L3 vertebra based on radiological findings, including plain radiograph, computed tomography, and magnetic resonance imaging...

Solid Variant of Aneurysmal Bone Cyst (SVABC) is an uncommon neoplasm seen in young patients. The lesion presents clinically as well as on radiology like a malignant bone tumour. The aggressive features in most of the cases lead to a wrong diagnosis. Radiologically, it is expansile osteolytic with cortical breach being seen in many of the cases. We report two cases of SVABC which were misdiagnosed as malignant bone tumours. Both cases were seen in long bones. Radiologically both lesions were expansile, osteolytic, solid cystic, with destruction of cortex and were diagnosed as osteosarcomas...

Differentiating osteoclast-rich lesions of bone (giant cell tumor of bone [GCTB], chondroblastoma [CBA], and aneurysmal bone cyst [ABC]) can be challenging, especially in small biopsies or fine needle aspirations. Mutations affecting codons 34 and 36 of either H3 Histone Family Member 3A (H3F3A) and/or 3B (H3F3B) are characteristically seen in GCTB and CBAs. We devised a simple assay to identify these mutations and evaluated its applicability for routine clinical diagnosis. 124 tissue specimens from 108 patients (43 GCTBs, 38 CBAs and 27 ABCs) were collected from the archives of the Calgary Laboratory Services/University of Calgary and Vanderbilt University Medical Center...

Hydatid cyst is usually located in the liver and lungs, rare cases showing localization in other organs or tissues. In the unusual location, echinococcosis is an excluding diagnosis that is established only after microscopic evaluation. Our first case occurred in a 67-year-old female previously diagnosed with pulmonary tuberculosis and hospitalized with persistent pain in the hip joint. The clinical diagnosis was tuberculosis of the joint, but the presence of the specific acellular membrane indicated a hydatid cyst of the synovial membrane, without bone involvement...

An aneurysmal bone cyst (ABC) is believed to be attributable to intraosseous circulatory disturbance. An ABC is a vascular tumor of the bone caused by bony expansion after partial vascular occlusion and congestion. Most ABCs are found in adolescents (approximately 75% of ABCs are observed in patients under 20 years of age). The most common ABC sites are the long bones of the limbs, the vertebrae, and the cranial bone. Aneurysmal bone cysts in the skull base or ethmoid sinus have been but rarely reported worldwide...

Giant cell tumor (GCT) is one of the most common tumors of bone and is the most common precursor of aneurysmal bone cysts (ABC). The clinical behavior of concurrent GCT and ABC can be very aggressive in children. GCT of the ribs, with or without ABC, is rarely seen in children. We report a case of an 8-year-old girl with GCT and associated ABC of the ribs who presented with sudden onset of chest pain and breathlessness due to a hemothorax. The patient was successfully treated by surgical resections and arterial embolization...

We report development of an aneurysmal bone cyst (ABC) that was located in the proximal region of the femur in an 11-year-old girl. Over a period of 30 weeks, the ABC showed fulminant local progression, with destruction of the bone, which led to an abrupt loss of function of the left hip. The standard tumour treatment protocol was followed. We performed embolisation of the tumour followed by a biopsy, which confirmed the diagnosis of ABC. The outcome was negative with total destruction of the proximal third of the femur, despite repeating the embolisation...

BACKGROUND: Aneurysmal bone cysts are an uncommon form of benign primary bone tumors; affection of the hand is very rare. METHODS: A rigorous review of the literature showed that this type of tumor has not previously been described in the pisiform. In this article, we report the occurrence of an aneurysmal bone tumor in the pisiform of the left hand of a 19-year-old male. RESULTS: This tumor was successfully treated through surgical excision with an uneventful recovery...

Solid variant aneurysmal bone cyst is a rare benign bone lesion, representing a small fraction of all aneurysmal bone cysts. The imaging appearance and histologic features may overlap with other benign and malignant neoplasms, posing a diagnostic dilemma for clinicians, pathologists, and radiologists. We present a case of solid variant aneurysmal bone cyst of the distal fibula and review the radiologic and histologic features important for diagnosis.

Anevrysmal bone cyst is an aggressive, destructive but benign lesion in the long bones, spine or basin, affecting mainly children and young adults. However, it is a very rare tumor. We here report the case of a 8-year old boy with a very rare localization of anevrysmal cyst in the clavicle, initially presenting with pathologic bone fracture, that is a benign cystic lesion. The child underwent complete radical resection of the cyst located at the level of the right clavicle, followed by anatomopathological examination of surgical specimen which confirmed the diagnosis...

Aneurysmal bone cyst (ABC) is an expansile cystic lesion that may affect any bone of the skeleton. Although exceedingly rare, lesions with histomorphologic characteristics of an ABC have reportedly originated within soft tissue. Extraskeletal ABC may mimic a variety of benign and malignant lesions and can be confused with other more common or rare giant cell-rich tumors of soft tissue, especially myositis ossificans. Clinical, radiological and histologic correlation is crucial in reaching the correct diagnosis...

The optimal treatment of aneurysmal bone cyst remains challenging. The aim of this prospective study was to evaluate the results of using bone grafts shaped to the defects caused by aneurysmal bone cysts of upper limb bones. Fifteen patients (12 males and 3 females) with an average age of 12 years (range 6-16 years) were treated for aneurysmal bone cysts of upper limb bones by intralesional resection, argon beam coagulation and shaped bone graft. The grafts were harvested from 14 patients (11 fibulas and 3 iliac bones) and from the mother of one patient (proximal fibula)...
