El osteosarcoma “tipo osteoblastoma”, una variante menos agresiva del osteosarcoma, es una enfermedad poco frecuente y representa un desafío diagnóstico tanto clínico como histopatológico. Se han publicado escasos reportes de casos de este tumor.Presentamos a un paciente de 16 años con un osteosarcoma “tipo osteoblastoma” localizado en la columna cervical. La biopsia ósea bajo tomografía reveló una lesión con un patrón de crecimiento permeativo, con sospecha de osteosarcoma “tipo osteoblastoma”. Se realizó una espondilectomía total en bloque mediante un doble abordaje. Se describen el caso clínico, la secuencia diagnóstica, la técnica quirúrgica y el seguimiento a 10 años. ABSTRACT Osteoblastoma-like osteosarcoma; a less aggressive variant of osteosarcoma;is a rare entity and represents a clinical and histopathological diagnostic challenge. We have found few reports of cases of this tumor in the literature. In this case we describe an osteoblastoma-like osteosarcoma located in the cervical spine in a 16-year-old patient. Tomography guided bone biopsy showed a lesion with a permeative growth pattern with suspicion of an osteoblastoma-like osteosarcoma. A total block spondylikectomy wasperformed through a double approach. We present the clinical case, the diagnostic sequence, the surgical technique and 10-year follow-up.

Riedel's Thyroiditis

Riedel’s thyroiditis is a rare entity consisting of a fibrotic process of the thyroid which can generate gland destruction, infiltration of cervical structures and even airway obstruction. It has been associated with systemic fibrotic disorders, autoimmune diseases, and more recently with spectrum of diseases related to excess of Immunoglobulin G type 4 (IgG4). Two cases of Riedel’s thyroiditis by IgG4, confirmed by immunohistochemistry and was managed surgically with favorable results during the follow-up time, are presented. These case descriptions highlight the diagnostic challenge of this disease, describe the response with surgical management, and make a brief update on the subject.

Sclerosing angiomyolipoma (sAML) is a rare variant of the perivascular epithelioid tumors exhibiting distinct morphology with extensive stromal hyalinization, which makes it challenging to recognize. It often lacks an adipose tissue component and melanocytic markers may be expressed only focally, further posing a diagnostic challenge. Here, we report a case of sAML of the left pararenal retroperitoneum in a 52-year-old woman with 92 months of clinical follow up and discuss the histologic features, immunoprofile, molecular alterations, and differential diagnoses that can aid in the diagnosis of this unique and rare entity.

Lingual osseous choristoma is a rare benign tumor consisting of normal matured bone tissue. It was first reported in 1913, and less than 100 cases of lingual osseous choristomas, mainly in their twenties and thirties, have been reported in the English literature until now. Here, we report an additional case of lingual osseous choristoma, in an elderly patient, that was incidentally removed by coughing and cured without additional interventions. An 89-year-old male patient was referred to our department for an evaluation of chronic cough. When we examined his oral cavity and pharynx, he expectorated a 10 -mm mass which was histologically diagnosed as an osseous choristoma. We confirmed the well-defined, rounded, high-density mass with a tiny pedicle on the base of the tongue in previous cervical spine CT images. No signs of recurrence were found during the 15-month follow-up examination. Our case serves as a reminder of this rare entity in the diagnosis of tongue masses of the elderly.

Background & Aims: Autoimmune pancreatitis (AIP) is a fibroinflammatory condition affecting the pancreas and could present as a multisystem disorder. Diagnosis and management can pose a diagnostic challenge in certain groups of patients. We report our experience of managing this condition in a tertiary pancreaticobiliary centre in the North East of England.Methods: Patients were identified from a prospectively maintained database of patients diagnosed with AIP between 2005 and 2013. Diagnosis of definite/probable AIP was based on the revised HISORt criteria. When indicated, patients were treated with steroids and relapses were treated with azathioprine. All patients have been followed up to date.Results: Twenty-two patients were diagnosed with AIP during this period. All patients had pancreatic protocol CT performed while some patients had either MR or EUS as part of the work up. Fourteen out of 22 (64%) had an elevated IgG4 level (mean: 10.9 g/L; range 3.4 - 31 g/L). Four (18%) patients underwent surgery. Extrapancreatic involvement was seen in 15 (68%) patients, with biliary involvement being the commonest. Nineteen (86%) were treated with steroids and five (23%) required further immunosuppression for treatment of relapses. The mean follow up period was 36.94 months (range 7 - 94).Conclusion: Autoimmune pancreatitis is being increasingly recognized in the British population. Extrapancreatic involvement, particularly extrahepatic biliary involvement seems to be a frequent feature.Diagnosis should be based on accepted criteria as this significantly reduces the chances of overlooking malignancy. Awareness of this relatively rare condition and a multi-disciplinary team approach will help us to diagnose and treat this condition more efiectively thereby reducing unnecessary interventions.

Experienced Pain

We report about a 14-year-old boy who presented with an anterior mediastinal mass that was diagnosed as malignant teratoma. Surgical resection was performed along with pre- and postoperative chemotherapy. Although elevated alpha-fetoprotein became negative, he experienced pain in his right hip joint 3 months after resection. Systematic evaluation revealed multiple locations of metastasis, and the pathological diagnosis based on bone biopsy was malignant melanoma originating from malignant teratoma, which rapidly progressed. He died 15 months after diagnosis of the original malignant teratoma. Diagnosing and treating malignant transformation of teratoma, including malignant melanoma, is difficult because it is very rare. To our knowledge, this is the second reported case of malignant melanoma arising from a mediastinum malignant teratoma, with both cases having a poor prognosis. In addition to the follow-up of tumor markers, systematic evaluation, including imaging, should be considered even after remission to monitor malignant transformation of teratoma. We expect to establish a successful therapy and improve mortality rate after more such cases are accumulated.

Mild Dysphagia

Study Design: Retrospective multicenter. Objectives: diffuse idiopathic skeletal hyperostosis (DISH) involving the cervical spine is a rare condition determining disabling aero-digestive symptoms. We analyzed impact of preoperative settings and intraoperative techniques on outcome of patients undergoing surgery for DISH. Methods: Patients with DISH needing for anterior cervical osteophytectomy were collected. Swallow studies and endoscopy supported imaging in targeting bone decompression. Patients characteristics, clinico-radiological presentation, outcome and surgical strategies were recorded. Impact on clinical outcome of duration and time to surgery and different surgical techniques was evaluated through ANOVA. Results: 24 patients underwent surgery. No correlation was noted between specific spinal levels affected by DISH and severity of pre-operative dysphagia. A trend toward a full clinical improvement was noted preferring the chisel ( P = 0.12) to the burr ( P = 0.65), and whenever C2-C3 was decompressed, whether hyperostosis included that level ( P = 0.15). Use of curved chisel reduced the surgical times ( P = 0.02) and, together with the nasogastric tube, the risk of complications, while bone removal involving 3 levels or more ( P = 0.04) and shorter waiting times for surgery ( P < 0.001) positively influenced a complete swallowing recovery. Early decompressions were preferred, resulting in 66.6% of patients reporting disappearance of symptoms within 7 days. One and two recurrences respectively at clinical and radiological follow-up were registered 18-30 months after surgery. Conclusion: The “age of DISH” counts more than patients’ age with timeliness of decompression being crucial in determining clinical outcome even with a preoperative mild dysphagia. Targeted bone resections could be reasonable in elderly patients, while in younger ones more extended decompressions should be preferred.

Background: Large frontoencephaloceles, more common in low and middle-income countries, require complex reconstruction of cerebral herniation, elongated nose, telecanthus, and cephalic frontal bone rotation. Previously described techniques involve multiple osteotomies, often fail to address cephalad brow rotation, and have high complication rates including up to 35% mortality. This study presents a novel, modified, single-staged technique for frontoencephalocele reconstruction performed by Mercy Ships. This technique, which addresses functional and aesthetic concerns with minimal osteotomies, may help improve outcomes in low resources settings. Methods: Retrospective review was performed of patients who underwent frontoencephalocele reconstruction through Mercy Ships using the technique described. Patient data including country, age, gender, associated diagnoses, and prior interventions were reviewed. Intraoperative and post-operative complications were recorded. Results: Eight patients with frontoencephalocele (ages 4-14 years) underwent surgery with the novel technique in 4 countries. Average surgical time was 6.0 ± 0.9 hours. No intraoperative complications occurred. Post-operatively 1 patient experienced lumbar drain dislodgement requiring replacement and a second had early post-operative fall requiring reoperation for hardware replacement. In person follow-up to 2.4 months showed no additional complications. Follow-up via phone at 1 to 2 years post-op revealed all patients who be satisfied with surgical outcomes. Conclusions: Reconstruction of large frontoencephaloceles can be challenging due to the need for functional closure of the defect and craniofacial reconstruction to correct medial hypertelorism, long nose deformity, and cephalad forehead rotation. The novel surgical technique presented in this paper allows for reliable reconstruction of functional and aesthetic needs with simplified incision design, osteotomies, and bandeau manipulation.
