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.

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).

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.

Pathologisches Institut, Universitätsklinik Freiburg, Breisacher Str. 115, 79106, Freiburg, Deutschland.

Primary cartilage-forming tumors of the bone are frequent entities in the daily work of skeletal radiologists. This article describes the correlation of pathology and radiology in cartilage-forming skeletal tumors, in particular, enchondroma, osteochondroma, periosteal chondromas, chondroblastoma and various forms of chondrosarcoma. After reading, the radiologist should be able to deduce the different patterns of cartilage tumors on radiographs, CT, and MRI from the pathological aspects. Read More

Aneurysmal bone cyst secondary to a giant cell tumor of the patella: A case report.

Oncol Lett 2016 Feb 7;11(2):1481-1485. Epub 2016 Jan 7.

Department of Orthopedics, The First Affiliated Hospital of Nanchang University, Artificial Joints Engineering and Technology Research Center of Jiangxi Province, Nanchang, Jiangxi 330006, P.R. China.

The patella is an unusual location for primary and metastatic bone tumors to develop. The most frequently encountered primary osteolytic lesions at the patella include giant cell tumors of the bone (GCT), chondroblastoma and aneurysmal bone cysts (ABC). However, the presentation of an ABC originating secondary to a GCT at the patella is rare. Read More

What Happens to the Articular Surface After Curettage for Epiphyseal Chondroblastoma? A Report on Functional Results, Arthritis, and Arthroplasty.

Clin Orthop Relat Res 2017 Mar;475(3):760-766

Carlos E. Ottolenghi Institute of Orthopedics, Italian Hospital of Buenos Aires, Potosí 4247 (1199), Buenos Aires, Argentina.

Background: Chondroblastoma is an uncommon, benign, but locally aggressive bone tumor that occurs in the apophyses or epiphyses of long bones, primarily in young patients. Although some are treated with large resections, aggressive curettage and bone grafting are more commonly performed to preserve the involved joint. Such intralesional resection may result in damage to the growth plate and articular cartilage, which can result in painful arthritis. Read More

Atypical giant chondroblastoma mimicking a chondrosarcoma.

J Cancer Res Ther 2015 Jul-Sep;11(3):660

Department of Radiology, Tata Memorial Centre, Dr. Ernest Borges Marg, Parel, Mumbai, Maharashtra, India.

Chondroblastoma is a rare, benign tumor derived from chondroblasts, commonly presenting in the second decade of life. It is usually found in the epiphysis or apophysis of long bones; however, it may rarely affect flat bones like scapula. Occasionally a histologically typical chondroblastoma may exhibit an aggressive behavior that is not normally associated with benign tumors such as a large size, pulmonary metastases, joint and soft-tissue infiltration and local recurrence.
