Osteoblastoma is a rare benign tumor of the bone. A 15-year-old boy presented with severe neck and back pain and was followed up for myofascial pain syndrome for 12 months. There was no neurologic deficit or scoliosis. The X-ray of the patient was normal. MRI revealed local destructive tumorous lesion of the T3-T5 vertebrae. The tumor was resected by a spinal surgeon and histologic examination revealed osteoblastoma. The patient's complaints have been completely resolved and there was no recurrence during the follow-up.

Glomus tumor is a rare perivascular benign tumor arising from the Sucquet-Hoyer canal of the normal glomus body, most commonly in the digital areas. We report a serving soldier with such a tumor in an atypical site, the perianal region, presenting with episodic shooting pain. Total surgical excision was performed. Histopathology revealed a well-circumscribed tumor composed of clusters of monotonous polygonal cells surrounding capillary-sized blood vessels. Tumor cells also showed immunopositivity for smooth muscle antigen and vimentin. Following excision, the patient was completely relieved of pain and there was no recurrence on follow-up for 6 months.

As a largely under-recognized problem, snapping scapula stems from the disruption of normal mechanics in scapulothoracic articulation. It is especially common in the young, active patient population, and symptoms are frequently seen with overhead and throwing motions. Understanding the anatomy of the scapula and surrounding neurovascular structures is crucial in making a differential diagnosis and providing both nonoperative and surgical treatments. Common causes of snapping scapula include bursitis, muscle abnormality, and bony or soft-tissue abnormalities. Anatomic variations, such as excessive forward curvature of the superomedial border of the scapula, may also be a cause for snapping. Benign tumor conditions of the scapula can also predispose one to snapping scapula syndrome and should be thoroughly investigated during the course of treatment. Patients with snapping scapula syndrome typically present with a history of pain with overhead activities. Snapping scapula is associated with audible and palpable crepitus near the superomedial border of the scapula. Various imaging studies may be used to rule out soft-tissue and bony masses, which may cause impingement at the scapulothoracic articulation. In most cases nonoperative treatment is curative and includes physical therapy for scapular muscle strengthening and nonsteroidal anti-inflammatory medications. Corticosteroid injections may also be used for therapeutic and diagnostic purposes. In most cases overuse injuries and repetitive strains respond well to nonoperative treatments. When nonoperative measures fail, surgery is a proven modality, especially if a soft-tissue or bony mass is implicated. Both open and arthroscopic techniques have been described with predictable results.

Osteoid osteoma is a benign tumor commonly found in young patients. The most interesting feature of the tumor is its peculiar obvious pain. The intensity of pain produced by osteoid osteoma is unproportionate to its nature and size. Much has been written about the mechanism of this symptom of the tumor and the specific characteristics of the pain that can be misleading when appearing as radicular pain especially when some subtle neurologic signs and symptoms accompany the pain. In this article, 12 patients who were referred to our clinic with radicular pain and neurological signs and symptoms months after initiation of symptoms between 2000 and 2008 are presented. Of these 12 patients, most were first thought to have root compression disease before being referred to our hospital. Precise history taking and special attention to physical examinations led to a suspicion of osteoid osteoma. Plain radiographs, computed tomography, and bone scans indicated osteoid osteoma, and excisional biopsy confirmed its diagnosis. Osteoid osteoma should always be considered in young patients with radicular pain, even with subtle neurological signs and symptoms.

This was a retrospective study of all the cases of ovarian tumours operated in Nepal Medical College Teaching Hospital from January 2006 to July 2008. All the cases of ovarian tumour were included, irrespective of whether diagnosed preoperatively or found incidently during operation. The nature of tumour whether benign or malignant, their presenting symptoms, age, parity age of menarche, type of operation and histopathological finding was recorded. The incidence of ovarian tumour was 16.7% among total gynaecological admissions, out of which malignant ovarian tumour was 9.5%. The age range was 18 to 70 years. Benign tumour occurred in all age group 86 (90.5%) while maximum of malignant tumour occurred after 40 years (66.7%). Eleven point six percent were unmarried, 20.0% nulliparous, 7.4% were pregnant and 38.9% were of one to two parity. 10.0% were asymptomatic and commonest symptom was pain in lower abdomen (84.0%). Seventy two point six percent were surface epithelium tumour which is common in older women. Twenty seven percent were germ cell tumour which is common in younger age group. Commonest surface epithelial tumour was serous cyst adenoma (40.0%) and commonest germ cell tumour was Dermoid (25.3%).Commonest complication of ovarian cyst was torsion (12.6%).

Osteoblastoma is an extremely rare entity that represents less than 1% of all bone tumors, and affects twice as many males as females with peak incidence between 15 and 20 years. Osteoblastomas commonly affect axial bones, long bones, bones of the foot and hand, and less commonly the pelvis, scapula, ribs, and clavicle. Osteoblastoma does not have a classic presentation, but can vary with the location and size of the tumor. The main complaint is often progressive pain localized at the tumor site. Osteoblastoma is a benign tumor with an aggressive behavior. The treatment is wide surgical resection, otherwise it continues to enlarge and destroy the bone and surrounding structures. We report a 32-year-old male with an osteoblastoma of this sternum who was treated with an en-bloc resection and reconstruction with Marlex((R)) and a methylmethacrylate plate.

An osteoma is a benign tumor essentially restricted to the craniofacial skeleton. Osteomas occur most frequently in the frontal, ethmoid, and maxillary sinuses, and rarely affect the glenoid fossa. Osteomas are usually pain-free and remain silent, ie, symptom-free, for many years but may lead to occlusal changes. The report describes the case of an adult man with an osteoma who presented with a chief complaint of malocclusion and who was misdiagnosed. The case points to the diagnostic reasoning necessary to arrive at a correct diagnosis, especially when signs and symptoms, as well as pathology, are rare, eg, not familiar to the clinician.

Giant cell tumor is a benign tumor of bone with a predilection for juxta-articular locations. Although not malignant, giant cell tumor often exhibits unpredictable and locally aggressive behavior, and in rare cases can metastasize in the absence of histologic malignancy. Partial tumor necrosis has been infrequently reported within typical giant cell tumor. A 17-year-old girl presented with a right distal femur giant cell tumor associated with complete tumor necrosis on histopathologic analysis. The etiology, prevalence, and implications of complete necrosis in previously untreated giant cell tumor of bone remain unclear, as there are no previously published reports. Despite the complete necrosis evident in our patient, she nonetheless presented with pain. There were no radiographic signs of the necrotic tumor space remodeling with new bone. The patient was treated with standard extended intralesional curetting through a generous cortical window permitting visualization of the entire lesion, and systematic high speed burring and thermal electrocautery ablation of the periphery, followed by micro particulate allogenic bone grafting. At short-term follow-up, she had healed well with no evidence of tumor recurrence. This article presents the first case, to our knowledge, of complete spontaneous tumor necrosis in a previously untreated bone giant cell tumor. Increased understanding of spontaneous tumor necrosis associated with giant cell tumor may help guided future targeted medical and surgical treatment modalities.

Aneurysmal bone cyst accounts for 1% of primary bone tumors and is one of the benign tumor-like lesions. Patellar involvement is quite rare. Its development on the basis of any previous lesion such as chondroblastoma is called secondary aneurysmal bone cyst. A 26-year-old male patient presented with right knee pain of three-year history. Physical examination showed a firm, immobile swelling at the anterior aspect of the right knee, without increase in temperature or redness of the skin. There was no pain on palpation and joint range of motion was normal. Radiological studies were suggestive of an aneurysmal bone cyst. At surgery, the cystic lesion was removed via curettage and the residual cavity was filled with an autogenous bone graft taken from the iliac wing. The histopathologic diagnosis was secondary aneurysmal bone cyst in association with chondroblastoma. During a 1.5-year follow-up, the patient had no complaint and no recurrence was observed.

Malignant pigmented villonodular synovitis (PVNS) is an extremely rare lesion. Approximately 30 cases of malignant PVNS have been reported to date and of these, only 1 case involved the temporomandibular joint. Owing to the rarity of well-documented cases and the heterogeneous histologic features of this group of tumors, there has been some confusion regarding its diagnosis. The heterogeneous features of the sarcomatous areas contain fibrosarcomatous, myxosarcomatous, malignant fibrous histiocytomalike or giant cell tumorlike patterns. However, despite the absence of frank sarcomatous change in the histopathogy of PVNS, there have been 3 reported cases of metastatic lesions in the lung or lymph nodes. Here we present an additional case of clinically malignant PVNS with pulmonary metastasis after recurrence. A 29-year-old man presented in our hospital with a recurrent swelling and pain in the right preauricular area, where benign tumor had been previously resected. MRI demonstrated a large mass with a low signal intensity that seemed to demonstrate a ferromagnetic effect. Surgical resection of the lesion was performed and the diagnosis of PVNS with focal atypical cells was made. Unfortunately, at 30 months post surgery, a thoracic CT found a metastatic nodule in the left lower lobe of the lung.
