J Maxillofac Oral Surg 2019 Mar 15;18(1):46-51. Epub 2017 Dec 15.

Department of Oral and Maxillofacial Pathology, Tamil Nadu Government Dental College and Hospital, The Tamil Nadu Dr. MGR Medical University, Chennai, 600 003 India.

Cartilage analogue of fibromatosis is a relatively common tumor in the palms and soles of young children and adolescence. The characteristic histological finding of the tumor is the differentiation toward cartilage formation within a background of fibromatosis-like growth. Therefore, the tumor may cause potential diagnostic problems in the maxillofacial bones where it has not been described. Read More

Chondrosarcoma arising within synovial chondromatosis of the lumbar spine.

Skeletal Radiol 2019 Feb 5. Epub 2019 Feb 5.

Department of Radiology and Department of Orthopedics, Mayo Clinic, 200 First Street SW, Rochester, MN, 55905, USA.

Synovial chondromatosis is an uncommon benign neoplasm that usually affects large appendicular joints and only rarely the spine. There are only a few small series and case reports documenting malignant transformation of synovial chondromatosis into secondary chondrosarcoma, typically within the hip in the setting of recalcitrant disease and multiple recurrences. Chondrosarcoma arising in synovial chondromatosis of the spine is exceedingly rare, with only one previously published case report involving the craniocervical junction. Read More

Structural Features of Heparan Sulfate from Multiple Osteochondromas and Chondrosarcomas.

Molecules 2018 Dec 11;23(12). Epub 2018 Dec 11.

Department of Medical Genetics and Rare Orthopaedic Diseases & CLIBI Laboratory-IRCCS, Istituto Ortopedico Rizzoli, V. di Barbiano 1/10, 40136 Bologna, Italy.

Multiple osteochondromas (MO) is a hereditary disorder associated with benign cartilaginous tumors, known to be characterized by absence or highly reduced amount of heparan sulfate (HS) in the extracellular matrix of growth plate cartilage, which alters proper signaling networks leading to improper bone growth. Although recent studies demonstrated accumulation of HS in the cytoplasm of MO chondrocytes, nothing is known on the structural alterations which prevent HS from undergoing its physiologic pathway. In this work, osteochondroma (OC), peripheral chondrosarcoma, and healthy cartilaginous human samples were processed following a procedure previously set up to structurally characterize and compare HS from pathologic and physiologic conditions, and to examine the phenotypic differences that arise in the presence of either exostosin 1 or 2 ( or ) mutations.

The usefulness of wide excision assisted by a computer navigation system and reconstruction using a frozen bone autograft for malignant acetabular bone tumors: a report of two cases.

BMC Cancer 2018 Oct 24;18(1):1036. Epub 2018 Oct 24.

Department of Orthopaedic Surgery, Graduate School of Medical Sciences, Kanazawa University, 13-1 Takara-machi, Kanazawa, 920-8641, Japan.

Background: Difficult resection of tumors from regions with complex local anatomy, such as the pelvis and sacrum, is likely to result in inadequate surgical margins (intralesional or marginal); this is because three-dimensional osteotomy is difficult particularly around the acetabulum. Additionally, removal of the joint makes reconstruction very difficult; thus, retention of good function also becomes difficult. In musculoskeletal oncology, computer navigation systems are still not widely used to prevent tumor-positive margins. Read More

The Chopsticks Technique for Endoscopic Endonasal Surgery-Improving Surgical Efficiency and Reducing the Surgical Footprint.

World Neurosurg 2018 Sep 7;117:208-220. Epub 2018 Jun 7.

Department of Neurosurgery, Hôpital Lariboisière (AP-HP), Paris, France; Paris VII-Diderot University, Paris, France.

Background: Variations and additions to the endoscopic endonasal exposure have been proposed around a modular strategy. These extensions are often necessary to provide additional working space and reduce conflict between the instruments and the endoscope. Resection of endonasal structures, which affects negatively the sinonasal quality of life, is thus undertaken not only to obtain tumor exposure but also to improve the maneuverability of the instruments.

False-positive findings on 6-[18F]fluor-l-3,4-dihydroxyphenylalanine PET (F-FDOPA-PET) performed for imaging of neuroendocrine tumors.

Eur J Endocrinol 2018 Aug 6;179(2):127-135. Epub 2018 Jun 6.

Department of EndocrinologyUniversity of Groningen, University Medical Center Groningen, Groningen, The Netherlands.

Background/aim: PET with 6-[18F]fluor-l-3,4-dihydroxyphenylalanine (F-FDOPA) has been shown to be a useful imaging tool with a high sensitivity for the visualization of neuroendocrine tumors (NETs). F-FDOPA uptake in tumors other than NETs has been suggested previously, but data on this phenomenon are limited. We therefore studied the non-physiological, false-positive uptake of F-FDOPA in a large population of patients with a NET or with a high clinical suspicion of harboring a NET. Read More

Adult Laryngeal Ossified Hemangioma: Difficulties in Differential Diagnosis.

J Craniofac Surg 2018 Nov;29(8):e730-e732

Department of Otorhinolaryngology, Head and Neck Surgery, University of Piemonte Orientale "Amedeo Avogadro," Novara, Italy.

Adult laryngeal hemangiomas are uncommon and often poorly symptomatic. The authors describe a laryngeal hemangioma with acute airway obstruction and radiologic findings suggesting a chondrosarcoma-like neoplasm, while pathologic features were consistent with an ossified hemangioma. The presence of fields of bone metaplasia into a classical cavernous hemangioma is an unusual phenomenon which, to our knowledge, was never previously described in the larynx. Read More

Unsintered Hydroxyapatite and Poly-L-Lactide Composite Screws/Plates for Stabilizing β-Tricalcium Phosphate Bone Implants.

Clin Orthop Surg 2018 Jun 18;10(2):253-259. Epub 2018 May 18.

Department of Orthopaedic Surgery, Kyoto University, Kyoto, Japan.

Unsintered hydroxyapatite (u-HA) and poly-L-lactide (PLLA) composites (u-HA/PLLA) are osteoconductive and biodegradable. Screw (Super-Fixsorb MX30) and plate (Super-Fixsorb MX40 Mesh) systems made of u-HA/PLLA are typically used in small bones in maxillofacial surgeries. After the resection of bone tumors in larger bones, reconstructions with β-tricalcium phosphate (β-TCP) implants of strong compression resistance have been reported. Read More

Computer-assisted surgery compared to fluoroscopy in curettage of atypical cartilaginous tumors / chondrosarcoma grade 1 in the long bones.

PLoS One 2018 17;13(5):e0197033. Epub 2018 May 17.

Department of Orthopaedics, University of Groningen, University Medical Center Groningen, Groningen, The Netherlands.

Introduction: Fluoroscopy is currently the standard imaging modality for curettage of atypical cartilaginous tumors/chondrosarcoma grade 1 (ACT/CS1). Computer-assisted surgery (CAS) is a possible alternative, offering higher resolution imaging and continuous three-dimensional feedback without ionizing radiation use. CAS hypothetically makes curettage more accurate, thereby decreasing residue or recurrence rate. Read More

Extraosseous Intradural Chondrosarcoma of the Cervical Spine: A Case Report with Brief Review of Literature.

Case Rep Radiol 2018 28;2018:6921020. Epub 2018 Feb 28.

Department of Radiology, SUNY Upstate Medical University, Room 3530, 750 East Adams Street, Syracuse, NY 13210, USA.

Mesenchymal chondrosarcoma (MCS) is a malignant cancer of the cartilage that accounts for less than 1% of all chondrosarcomas and typically occurs within the bone. One-third of all mesenchymal chondrosarcomas are extraosseous soft tissue sarcomas, rendering this as an uncommon entity. We report a rare case of an extraosseous chondrosarcoma with the cervical spinal canal in a 21-year-old male. Read More
