[Molecular pathology in the diagnosis of bone tumors: current concepts].

Pathologe 2020 Mar;41(2):106-115

Knochentumor-Referenzzentrum, Institut für Pathologie, Universitätsspital Basel, Universität Basel, Schönbeinstrasse 40, Basel, 4031, Schweiz.

The integrative evaluation of histology and corresponding imaging is essential for the classification of bone tumors. Until a few years ago, there were hardly any molecular markers that could be used for diagnostic purposes. However, exome- and genome-wide sequencing analyses have since uncovered a number of tumor-specific aberrations that can be very helpful in ambiguous cases. Read More

Vascularized Bone Autograft for the Treatment of Chondroblastoma of the Talus at Imminent Risk of Joint Breakdown: Three Case Reports.

J Foot Ankle Surg 2019 Mar 3;58(2):363-367. Epub 2019 Jan 3.

Professor, Associate Professor, and Chair, Clinic of Orthopaedic Surgery, Kantonsspital Baselland, Liestal, Switzerland.

Surgical treatment options in a chondroblastoma of the talus breaching the subchondral layer with imminent risk of talar collapse in the weightbearing area are limited. A joint-preserving surgery should be advocated. Because current treatment options such as curettage, cryosurgery, or radiofrequency ablation may not be able to prevent a talar dome breakdown in large defects, nonvascularized bone grafting has been advocated to fill the void.

Chondromyxoid Fibroma of the Pelvis: Institutional Case Series With a Focus on Distinctive Features.

Int J Surg Pathol 2019 Jun 23;27(4):352-359. Epub 2018 Dec 23.

1 Johns Hopkins University, Baltimore, MD, USA.

Chondromyxoid fibroma (CMF) is a relatively uncommon benign bone tumor of cartilaginous differentiation. The primary pitfall in the histopathologic diagnosis of CMF is confusion with a high-grade chondrosarcoma, owing to the atypical stellate and spindled cells set within a chondromyxoid background. CMF is particularly challenging to diagnose within the pelvis, where clinical suspicion for chondrosarcoma is high and benign lesions may grow to a large size to occupy the pelvic bones. Read More

Common Tumors and Tumor-like Lesions of the Shoulder.

J Am Acad Orthop Surg 2019 Apr;27(7):236-245

From the Department of Orthopaedics (Dr. Lee and Dr. Hills) and the Department of Radiology (Dr. Jordanov), Vanderbilt University Medical Center, Nashville, TN, and the OrthoSports Associates (Dr. Jaffe), Birmingham, AL.

Shoulder lesions range from tumor-like lesions such as simple bone cysts to aggressive high-grade sarcomas. The clinical presentation is often nonspecific with shoulder pain as the primary complaint, which may lead to a delayed or missed diagnosis. Delayed diagnosis or a poorly planned biopsy of a malignant shoulder lesion can have a detrimental effect on the patient's prognosis and treatment options. Read More

Diagnostic Immunohistochemistry for Soft Tissue and Bone Tumors: An Update.

Adv Anat Pathol 2018 Nov;25(6):400-412

Department of Pathology, Brigham and Women's Hospital, Harvard Medical School, Boston, MA.

Although some soft tissue and bone tumors can be identified based on histologic features alone, immunohistochemistry plays a critical diagnostic role for most mesenchymal tumor types. The discovery of recurrent genomic alterations in many benign and malignant mesenchymal neoplasms has added important biologic insights and expanded the spectrum of some diagnostic subgroups. Some tumors are defined by unique genomic alterations, whereas others share abnormalities that are not tumor-specific and can be observed in a sometimes broad range of biologically unrelated neoplasms.

Is Core Needle Biopsy Reliable in Differentiating Between Aggressive Benign and Malignant Radiolucent Bone Tumors?

Clin Orthop Relat Res 2018 03;476(3):568-577

V. Hegde, Z. D. C. Burke, H. Y. Park, S. D. Zoller, D. Johansen, B. V. Kelley, N. M. Bernthal, Department of Orthopaedic Surgery, University of California-Los Angeles, Santa Monica, CA, USA B.

Federman, Department of Pediatrics, University of California-Los Angeles, Los Angeles, CA, USA S. D. Nelson, Department of Pathology, University of California-Los Angeles, Santa Monica, CA, USA.

Background: Although there is widespread acceptance of core needle biopsy (CNB) for diagnosing solid tumors, there is reluctance by some clinicians to use CNB for aneurysmal bone cysts (ABCs) as a result of concerns of safety (bleeding, nerve injury, fracture, readmission, or infection) and reliability, particularly to rule out malignant diagnoses like telangiectatic osteosarcoma. This is especially true when CNB tissue is sent from an outside hospital, where the technique used to obtain the tissue may be spurious.

Questions/purposes: (1) Is CNB effective (provided adequate information to indicate appropriate surgical treatment without further open biopsy) as an initial diagnostic test for ABC? (2) Is CNB accurate (pathology consistent with the subsequent definitive surgical pathologic diagnosis) in differentiating between benign lesions such as primary or secondary ABCs and malignant radiolucent lesions such as telangiectatic osteosarcoma? (3) What are the complications of CNB? (4) Is there any difference in the effectiveness or accuracy of CNB performed at outside institutions when compared with a referral center?

Methods: A retrospective study of our musculoskeletal tumor board pathology database (1990-2016) was performed using search criteria "aneurysmal bone cyst" or "telangiectatic osteosarcoma. Read More

Chondroblastomas are very rare benign primary bone tumors occurring preferentially in the epiphyses or apophyses of long bones in children and adolescents. In most cases the typical histological and imaging findings lead to a correct diagnosis that may be substantiated by demonstrating the highly specific point mutation in the H3F3B gene (p.K36M), either by sequencing or immunohistochemistry.

Department of Applied Clinical Science & Biotechnology, University of L'Aquila, Piazzale Salvatore Tommasi 1, L'Aquila, Italy.

Introduction: Chondroblastoma (also known as Codman tumor) is a rare intermediate grade cartilaginous neoplasm, representing less than 1% of all primary bone tumors; it characteristically arises in the epiphysis or apophysis of a long bone in young patients, predominantly males. The most frequent location of chondroblastoma is the humerus (70% incidence rate) and more rarely it is located in the pelvis. When it affects the hip, the triradiate cartilage is the most common site. Read More

Benign Bone Conditions That May Be FDG-avid and Mimic Malignancy.

Semin Nucl Med 2017 07 12;47(4):322-351. Epub 2017 Apr 12.

Department of Radiology and Nuclear Medicine, Deventer Ziekenhuis, Deventer, The Netherlands.

Positron emission tomography with the radiotracer F-fluoro-2-deoxy-d-glucose (FDG) plays an important role in the evaluation of bone pathology. However, FDG is not a cancer-specific agent, and knowledge of the differential diagnosis of benign FDG-avid bone alterations that may resemble malignancy is important for correct patient management, including the avoidance of unnecessary additional invasive tests such as bone biopsy. This review summarizes and illustrates the spectrum of benign bone conditions that may be FDG-avid and mimic malignancy, including osteomyelitis, bone lesions due to benign systemic diseases (Brown tumor, Erdheim-Chester disease, Gaucher disease, gout and other types of arthritis, Langerhans cell histiocytosis, and sarcoidosis), benign primary bone lesions (bone cysts, chondroblastoma, chondromyxoid fibroma, desmoplastic fibroma, enchondroma, giant cell tumor and granuloma, hemangioma, nonossifying fibroma, and osteoid osteoma and osteoblastoma), and a group of miscellaneous benign bone conditions (post bone marrow biopsy or harvest status, bone marrow hyperplasia, fibrous dysplasia, fractures, osteonecrosis, Paget disease of bone, particle disease, and Schmorl nodes).

Chondroblastoma of the thoracic spine: a rare location. Case report with radiologic-pathologic correlation.

Skeletal Radiol 2017 Mar 13;46(3):367-372. Epub 2016 Dec 13.

Department of Radiology, University Hospital of Strasbourg, 1 avenue Moliere, 67098, Strasbourg, France.

Chondroblastoma is a rare benign cartilage neoplasm that arises from the appendicular skeleton in the vast majority of the cases (80%). Chondroblastoma of the spine is an even more rare condition (30 cases reported), and vertebral chondroblastomas, unlike chondroblastomas of the extremities, present with the appearance of an aggressive tumor on CT and MR imaging and occur at least a decade later. Even though vertebral chondroblastomas are very uncommon tumors, they should nonetheless be included in the differential diagnosis when encountered with an aggressive vertebral mass, and a histological confirmation should be performed.

Massive Chondroblastoma of the Talus: Treatment With En Bloc Talectomy and Tibiocalcaneal Arthrodesis: Long-Term Follow-up of a Case.

Foot Ankle Spec 2017 Jun 25;10(3):274-277. Epub 2016 Oct 25.

Hospital Clinico, University of Chile, Independencia, Santiago (LBM).

Chondroblastomas are benign bone tumors that are usually located at epiphyseal regions of long bones, and are rarely located at the talus. The usual treatment consists of curettage and filling of the bone defect with bone either bone grafts or some other material, such as cement. The authors present a case of a massive chondroblastma of the talus, extending outside of bone boundaries and with a huge soft tissue mass and invasion of the adjacent calcaneus. Read More
