An 18-month-old warmblood filly was 4/5 lame on the front right limb at referral and showed severe swelling of the right shoulder region and pain during manipulation of the shoulder region. Radiography revealed a roundish 5 × 7 cm radiolucent area with defined borders within the greater tubercle and the presence of a fracture of the lateral tubercle associated with the cyst. Cellular blood count was 27,500 WBC/μL and serum biochemical analyses revealed fibrinogen of 855 mg/dL. The fractured bone was removed surgically; the cyst debrided and filled with autologous cancellous bone graft. Three and five weeks after surgery the filly was reoperated on because of an osseous sequestrum and a periostal defect on the distal dorsolateral aspect of the pastern of the right hind limb and a septic synovitis of the DFTS of the left hind limb. Fifteen month after surgery the filly was not lame and was introduced to training. Unicameral bone cysts (UBC) are well described lesions, often associated to pathologic fracture in the proximal humerus of children but, until present, no scientific report exists of UBC in the foal. The prompt surgical management had a favorable outcome.

Introduction: The Unicameral Bone Cyst (UBC) is a benign osteolytic lesion primarily found in the metaphyseal part of long bones in children. It is important as it can involve growth plate involvement, cause pathological fractures and deformities of the affected limb. We report this case to emphasize that hip area pathologies can be represented with knee pain and discomfort. Case Presentation: The patient was a 9-year-old girl with a bone cyst in the right proximal femur, with functional knee pain and limping. The diagnosis was made after two years of pain in the knee area. As the cyst was symptomatic and the signs of impending pathological fracture were seen, the lesion was managed by curettage and fibular strut allograft and proximal humerus locking plate. Conclusions: The patient has been examined for knee joint problems for a long time, and her femur bone cyst was diagnosed after two years of pain. However, it could become a pathologic fracture or involve the growth plate and stop the limb’s growth, thus affecting the patient’s quality of life. Therefore, in children with chronic knee pain, careful assessment of the hip area is recommended.

Introduction Simple bone cyst is benign fluid-filled lesion localized mainly in long bones. It is usually diagnosed in the first two decades, the most common in proximal humerus. Unicameral bone cyst is o›en asymptomatic but can cause pathological fracture. Aim of the study The aim of our study was to evaluate clinical, diagnostic and treatment factors concerning patients with simple bone cyst. Material and methods The retrospective analysis was performed on 22 patients treated in Department of Traumatology, Orthopaedics and Hand Surgery in Poznań between 2001 and 2017. We have analyzed epidemiological factors: age and sex; symptoms; clinical examination: range of motion, presence of pain; X-ray: localisation, cyst index of Kaelin and MacEwan and presence of pathological fractures; treatment: methods, number of hospitalizations and effectiveness. Results Mean age of patients was 10.8. From 22 patients 11 were females. Generally bone cyst was diagnosed because of pathological fracture – 18 patients (85.7%). Other reasons of X-ray diagnostic were: pain – 2 patients (9.1%), deformity – 1 patient (4.5%), incidentally – 2 patients (9.1%). The bone cyst was localized in humerus – 21 patients (95.5%), radius – 1 patient (4.5%). Treatment methods were various: 7 patients (31.8%) – Depomedrol injections, 4 patients (18.1%) – marrow injections, 4 patients (18.1%) – marrow and Depomedrol injections, 5 patients (22.7%) – injections with additional bone gra›s, 3 patients (13.6%) – only bone gra›s. Conclusions Simple bone cyst occurs generally in young people (under twenty). The most common problem is a pathological fracture. Treatment is long and multistage.

Abstract Purpose Intraosseous schwannomas are extremely rare in the humerus, and less than 5 cases have been reported previously in the literature. This is the first report of its origin in the proximal humerus with pathologic fracture. we herein present this case for discussing the reason for its rarity and sharing our experience of management.Case presentation A 55-year-old female patient who presented with pain in the right shoulder, which caused by tripping and falling over a board. Radiographs, computed tomography (CT) and magnetic resonance imaging (MRI) showed considerable tumor in proximal humerus, which connected with a fracture. For this suspected tumor, we performed two operations. Pathological examination demonstrated typical picture of a schwannoma, showing whorls and interlacing fascicles of schwannoma spindle cells. Immunohistochemistry, The tumor cells were diffusely positive for S-100 protein, SOX-10 and CD68, while they were completely negative for desmin, DOG-1, AE1/AE3 and P63. The ki-67 index was about 10%. No mitoses or features of malignancy were identified. Finally, a diagnosis of benign schwannoma with focal of actively proliferated cells was made.Methods The treatment for intraosseous neurilemmomais with pathologic fracture include excisional biopsy, curettage, bone allograft, and fracture fixation. Results The patient recovered well. After the surgery, the patient gradually regained mobility and pain subsided. There was no recurrence after 6 months follow-up by X-ray.Conclusion In our case, the tumor with higher CD68 staining were likely to demonstrate that the tumor volume increase is not only based on cell proliferation, but also intratumoral hemorrhage, vascularization, and inflammation, which may be produce rarefaction of the bone and lead to bone fracture after a trivial trauma.
