A giant primary myxoid liposarcoma of the posterior mediastinum

Primary mediastinal liposarcoma is an uncommon neoplasm of intrathoracic origin. A case of a giant primary posterior mediastinal liposarcoma, mimicking a benign lipomatous lesion in shape and biological behavior and being successfully managed by complete surgical excision is presented here.

Traumatic panniculitis of the right thigh: a case report

Panniculitis is a group of diseases whose hallmark is inflammation of the subcutaneous adipose tissue that may be challenging both for the clinician and the dermatopathologist. It can occur in any fatty tissue (cutaneous or visceral) and is often diagnosed on the basis of a deep skin biopsy. Though mesenteric panniculitis is a common entity, and often associated with intra-abdominal inflammatory conditions, cutaneous panniculitis is a rare entity and can be mistaken for other skin and subcuteneous lesions. We present a patient with traumatic panniculitis.     

Primary mediastinal liposarcoma: a case report and review of the literature

A case of mediastinal liposarcoma (LPS) in a 49-year-old female is described. Primary LPS of the mediastinum are very rare tumors. They occur mainly in adults but may be encountered in children. They are characterized by their large size and their variable histologic subtypes, which correlate with the clinical behavior and the prognosis. The radiologic features are nonspecific but are suggestive of the diagnosis. A tissue biopsy is needed for the final diagnosis. The treatment of choice is surgical with wide margin resection. Chemotherapy and radiotherapy are ineffective modalities, used in unresectable or incompletely resected tumors. The prognosis depends on the histologic subtypes and completeness of surgical excision.

Extraarticular pigmented villonodular synovitis of the distal forearm: a case report

Extraarticular pigmented villonodular synovitis (PVNS) is very rare in the distal forearm. There has only been one previous case report of this disease in the extensor tendons of a child. We report a case of PVNS of the distal forearm that presented as two nodules over the radial aspect and a separate nodule on the ulnar aspect beneath the flexor carpi ulnaris tendon. Surgical exploration revealed an extensive extraarticular PVNS over the first and second dorsal compartment extensor tendons. On the anterior aspect it extended in the deep plane between the flexor tendons and the pronator quadratus and encased the radial artery completely. Complete excision of the tumour with the radial artery was done.     

Congenital rudimentary medial meniscus--report of a case of development arrest of medial meniscus

We present an unusual case, where the medial meniscus does not coincide with the embryological development of the formation of a discoid cartilage. A fairly, careful perusal of English literature since 1945 to date makes us feel that the following case merits recording. The meniscus had a normal anterior horn attached to the intercondylar area, in front of the anterior cruciate ligament. Medially, it was attached to the capsule and the condylar surface of the medial tibial plateau. The posterior horn was rounded, smooth, and floating free of any attachments. It was approximately 2 cms in length, semilunar in shape, and extended posteriorly up to the anterior margin of the medial collateral ligament. The rest of the medial tibial plateau had no other protective covering.

Giant liposarcoma occupying most of the hemi-thorax and resected in the supine position: report of a rare case

Liposarcoma originating in the thoracic cavity is not common. It has been reported that neither chemotherapy nor radiotherapy is effective, and that surgical resection is the only therapeutic option. There have been several cases reported of a large liposarcoma compressing adjacent organs such as the lung and the heart. In such cases, careful management is required to prevent adverse cardiopulmonary events during resection. Here we report a rare case of a 52-year-old male who had a giant liposarcoma occupying the majority of the right thorax. The patient was placed in the supine position, and the tumor was resected through an anterior thoracotomy. Percutaneous cardiopulmonary support (PCPS) was prepared in case of need. However, we succeeded in resecting the huge tumor without use of PCPS. We were unable to completely resect the tumor because it originated from the posterior mediastinum and extended into the left thorax. The resected tumor weighed 3,500 g and was 28 cm in largest diameter. The postoperative course was uneventful, except for hypoxemia lasting a few days caused by re-expansion edema in the lung. The patient was discharged and is alive at five years to date.     

Iatrogenic distal femur fracture following medial femoral supracondylar bone graft harvest: a case report and finite element analysis

Objective: This report presents a case of supracondylar femur fracture with finite element analysis and discusses its causes and prevention.Patient and Methods: A 53-year-old man presented with right talar osteonecrosis after osteosynthesis for a talus fracture. A medial femoral condyle-free vascularized bone graft (size, 20 × 12 × 17 mm) from the contralateral femur was performed, including the posteromedial cortical corner. The patient suffered a donor-site supracondylar femoral fracture while standing up from a cross-legged sitting position on the bed on postoperative day 6. The fracture was treated with intramedullary nailing. We analyzed the effects of the location of the bone graft harvest in an intact model using the three-dimensional finite element method (FEM).Results: The talar necrosis and the femur fracture healed. The FEM result revealed that the longitudinal axial pressure had minimal effect on the femur; however, the stress around the bone defect increased with rotation, especially in the posteromedial bone defect model.Conclusion: Harvesting the bone graft should not include the posteromedial corner of the supracondylar femur. The patient should strictly limit the motion of torsional stress, such as standing from a cross-legged sitting position or pivoting turn.
