Onychoscopy: an observational study in 237 patients from the Kashmir Valley of North India.

Dermatol Pract Concept 2018 Oct 31;8(4):283-291. Epub 2018 Oct 31.

Postgraduate Department of Dermatology, STD & Leprosy, Government Medical College, Srinagar, University of Kashmir, Jammu & Kashmir, India.

Background: Nail disorders comprise approximately 10% of all dermatological conditions. Because diagnosis is not always possible by clinical means alone, additional diagnostic procedures may be required at times. Dermoscopy of nails (onychoscopy) has shown promising results in diagnosing various nail disorders and also avoids time-consuming investigations such as culture and biopsy. Read More

Surgical therapy of benign and low-grade malignant intramedullary chondroid lesions of the distal femur: intralesional resection and bone cement filling with or without osteosynthesis.

Strategies Trauma Limb Reconstr 2018 Nov 3;13(3):163-170. Epub 2018 Nov 3.

Center of Orthopaedics, Trauma Surgery and Paraplegiology, Heidelberg University Hospital, Schlierbacher Landstraße 200a, 69118, Heidelberg, Germany.

Surgical treatment of benign and low-grade malignant intramedullary chondroid lesions at the distal femur is not well analyzed compared to higher-grade chondrosarcomas. Localization at the distal femur offers high biomechanical risks requiring sophisticated treatment strategy, but scientific guidelines are missing. We therefore wanted to analyze a series of equally treated patients with intralesional resection and bone cement filling with and without additional osteosynthesis. Read More

Enchondroma of Tibia as Potential False-positive Finding on 68Ga-DOTATOC PET/CT Scan.

Clin Nucl Med 2018 Oct 27. Epub 2018 Oct 27.

From the Molecular Imaging and Therapy Service, Department of Radiology, Memorial Sloan Kettering Cancer Center, New York, NY.

A 70-year-old man with a history of carcinoid tumor of small bowel was referred for Ga-DOTATOC study to evaluate the extent of disease. PET/CT scan revealed known metastatic disease in the liver, with other sites of involvement including pancreas, peritoneum, and bones. In addition, moderately intense uptake was noted in proximal right tibia and further correlation on CT showed metaphyseal lesion with "rings and arcs" calcification suggestive of enchondroma.

Individualized reconstruction for severe periprosthetic fractures around the tumor prosthesis of knee under assistance of 3D printing technology: A case report.

Medicine (Baltimore) 2018 Oct;97(42):e12726

Orthopedics Center, The Second Hospital of Jilin University.

Introduction: Periprosthetic femoral fractures (PFF) around tumor prosthesis of knee are stubborn problems for surgeons, huge bone defect and inappropriate biomechanics of the revision implant design can be disaster for reconstruction. With the development of three-dimensional (3D) printing technology, surgeons participate more in precise preoperative design and simulation for treatment of such fractures.

Department of Radiology, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, USA.

Benign lesions such as Paget's disease of the bone, enchondroma, osteochondromas, chronic osteomyelitis/infections and bone infarcts may rarely undergo malignant degeneration/transformation into sarcomas. To date, only 14 prior bone infarct-associated osteosarcomas have been described, with just two being primarily osteolytic. We discuss a case of a patient with a humeral bone-infarct, who presented with a presumed benign pathological fracture of the humerus through the bone infarct. Read More

Enchondromas and atypical cartilaginous tumors at the proximal humerus treated with intralesional resection and bone cement filling with or without osteosynthesis: retrospective analysis of 42 cases with 6 years mean follow-up.

World J Surg Oncol 2018 Jul 13;16(1):139. Epub 2018 Jul 13.

Center of Orthopaedics, Trauma Surgery and Paraplegiology, Heidelberg University Hospital, Schlierbacher Landstrasse 200a, 69118, Heidelberg, Germany.

Background: Enchondromas and atypical cartilaginous tumors (ACT) are often located at the proximal humerus. Most lesions can be followed conservatively, but surgical resection may alleviate pain, avoid pathological fractures, and prevent transformation into higher grade chondrosarcomas. Rigorous intralesional resection and filling with polymethylmethacrylate bone cement has been proposed for enchondromas but also for ACT, as an alternative for extralesional resection. Read More

Burdenko Neurosurgical Institute, 4-ya Tverskaya-Yamskaya Str., 16, Moscow, Russia, 125047.

Until recently, tumors of the clival region and ventral posterior cranial fossa were considered hard-to-reach and often inoperable via standard transcranial approaches. The introduction of minimally invasive methods combined with the endoscopic technique into neurosurgical practice has enabled removal of hard-to-reach tumors, including midline tumors of the ventral posterior cranial fossa.

To investigate the roles of B‑cell lymphoma‑2 associated athanogene 3 (BAG3) in human chondrosarcoma and the potential mechanisms, the expression levels of BAG3 were detected in the present study, and the associations between BAG3 and clinical pathological parameters, clinical stage as well as the survival of patients were analyzed. The present study detected BAG3 mRNA and protein expression in the normal cartilage cell line HC‑a and in SW1353 chondrosarcoma cells by reverse transcription‑quantitative polymerase chain reaction and western blot analysis. The BAG3 protein expression in 59 cases of chondrosarcoma, 30 patients with endogenous chondroma and 8 cases of normal cartilage was semi-quantitatively analyzed using the immunohistochemical method.

Peering beneath the surface: Juxtacortical tumors of bone (part I).

Clin Imaging 2018 Sep - Oct;51:1-11. Epub 2018 Feb 3.

Department of Radiology, Cleveland Medical Center, University Hospitals of Cleveland, Case Western Reserve University, Cleveland, OH, USA.

Juxtacortical or surface tumors of bone are neoplasms arising from or just outside the cortex, and are composed of different histologic types. Although the imaging appearances of these lesions have similarities to their intramedullary counterparts, their location alters their radiographic and MR characteristics, creating difficulties in diagnosis. Meanwhile, several non-neoplastic lesions, such as stress reaction/stress fracture and indolent infectious processes, compound the differential diagnosis. Read More

Periosteal chondroma of the cuboid with secondary aneurysmal bone cyst in a setting of secondary hyperparathyroidism.

Foot Ankle Surg 2018 Feb 22;24(1):71-75. Epub 2017 Sep 22.

Department of Foot and Hand Surgery, Agaplesion Diakonieklinikum Hamburg, Hohe Weide 17, 20259 Hamburg, Germany.

We report the case of a 35-year-old woman with painful, nontender mass at the right lateral hindfoot. Computed tomography (CT) and magnetic resonance imaging (MRI) indicated the suspect of a chondroid tumour in the cuboid. The tumour was resected en bloc and histology revealed the presence of a periosteal (juxtacortical) chondroma with secondary aneurysmal bone cyst. Read More
