Abstract
BACKGROUND Bone fine needle aspiration (FNA) presents several diagnostic challenges including limited sample material, reduced ability to assess the architecture, and lack of a standardised reporting system. The aim of our study is to present our experience regarding bone FNA. METHODS We performed a 6-year retrospective search of our archives to identify all FNA cases of bone lesions. Available data regarding patients' demographics, cytopathology, and surgical pathology were recorded. The FNA cases were then grouped into five categories (atypical, neoplasm-benign, neoplasm of unknown malignant potential, suspicious for malignancy, and malignant) and the risk of malignancy (ROM) was calculated. RESULTS A total of 341 FNA cases performed in 337 patients (M = 173, F = 164; mean age = 57.2 years) were identified. The iliac crest was the most commonly biopsied site (n = 134). The adequacy of bone FNA was 77.4%. The sensitivity and specificity regarding the nature of the lesion were 96.5% and 100%, respectively. The overall diagnostic accuracy of bone FNA was 77%. The accuracy of bone FNA for non-metastatic bone lesions including non-neoplastic lesions was 74%, while the diagnostic accuracy of bone FNA for a metastatic disease was 83.5%. The diagnostic accuracy for primary neoplastic lesions was 70%. The frequency (n,%) of cytomorphological categories were as follows: atypical (30, 8.8%); neoplasm-benign (6, 1.8%); neoplasm of unknown malignant potential (18, 5.3%); suspicious for malignancy (4, 1.2%); and malignant (145, 42.5%). The ROM in these categories was respectively as follows: 51.7%, 0%, 46.7%, 100%, and 99.1%. CONCLUSION FNA is a sensitive and specific technique for the diagnosis of bone lesions. In most instances, an accurate diagnosis can be achieved if adequate material, ancillary studies, and radiological correlation are available.

J Clin Orthop Trauma 2021; 18:74-79. [PMID: 33996452 PMCID: PMC8099782 DOI: 10.1016/j.jcot.2021.04.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Revised: 03/24/2021] [Accepted: 04/10/2021] [Indexed: 10/21/2022] Open
Abstract
INTRODUCTION Aneurysmal bone cysts (ABCs) are benign lesions of long bone metaphysis affecting mostly medullary region in younger age below 20 years of life. These may be originated rarely either in the cortex or in the superficial regions of diaphysis. The study highlighted the differences of diaphyseal lesions from the usual metaphyseal ones in view of their clinical, radiological and biological behavior and also discussed their management in brief. MATERIAL AND METHODS We reviewed a total of 84 aneurysmal bone cysts over the past fourteen years (2004-2017) and evaluated their surgical outcomes retrospectively. Total ten lesions were diaphyseal cortical in location (group I), while 74 lesions were conventional metaphyseal type (group II). RESULTS We observed that cortical ABCs were occurred commonly in diaphysis of femur, humerus, tibia and radius while presentation was at an older age than metaphyseal type. Radiographically these were eccentric lesion and more prone for pathological fractures than conventional type. These are differentiated radiographically from other benign lesions but also mimicking malignant conditions including low grade surface osteosarcoma and telangiectatic osteosarcoma while resemble similar to these on histopathological examination (HPE). CONCLUSION Biological behavior of cortical lesions does not differ significantly than conventional type but these are more prone for pathological fractures so these eccentric cortical ABC lesions should be treated with adequate internal fixation along with curettage and bone grafting. Although incidence of cortical or surface variety of ABCs is rare but surgeons might evaluate its severity in view of aggressive benign or malignant lesions of diaphysis.

Abstract
PURPOSE To describe the imaging, anatomic, and clinical features of a series of secondary aneurysmal bone cysts (ABC) and to ascertain their most commonly associated primary bone lesions. METHODS Forty-nine cases of histopathologically proven secondary ABCs were retrospectively reviewed. Demographic data and clinical history were obtained. Radiographic, computed tomographic, magnetic resonance, and nuclear medicine imaging were analyzed. Lesion location, imaging characteristics, and associated primary lesions were documented. Linear regression analysis and Chi-squared testing was performed for statistical analysis. RESULTS Twenty-four males and 25 females were included, with an age range of 8-79 years (mean 29.7 + - 4.5 years). Eleven types of primary bone lesion were identified, with giant-cell tumor (n = 17, 35%), chondroblastoma (n = 11, 22%), fibrous dysplasia (n = 6, 12%), osteoblastoma (n = 4, 8%) and osteosarcoma (n = 4, 8%) being the most frequent. The lesions involved chiefly the long bone epiphyses (n = 25, 51%). Secondary ABC imaging findings and locations most closely approximated those of their primary counterparts, although fluid-fluid levels were seen at a higher frequency than previously reported in primary chondroblastoma (9/11, 82%), fibrous dysplasia (2/6, 33%), osteoblastoma (4/4, 100%), osteosarcoma (3/4, 75%), and chondromyxoid fibroma (1/2, 50%). CONCLUSION The most common primary lesions associated with secondary ABC were giant cell tumor and chondroblastoma, located in the long bone epiphyses. The majority of the secondary ABCs demonstrate predominant imaging characteristics typical of the primary bone lesions, but with a higher presence of fluid-fluid levels.

Abstract
We report on a 19-year-old woman with a rapidly growing, solid variant of aneurysmal bone cyst (solid ABC) in the right part of the lateral mass of the sacrum. On admission, the magnetic resonance imaging (MRI) scan disclosed an inhomogeneous low intensity mass right of the centre of the os sacrum with a diameter of 38 x 64 mm and a height of 56 mm on T1 and T2 weighted images. The mass showed homogenous high signal intensity on Gd-enhanced images. Computed tomography demonstrated an expansile osteolytic lesion and (99m)Tc-methylene diphosphonate bone scintigraphy revealed uniform accumulation in the lesion. The histological evaluation showed a proliferation of fibroblasts, histiocytes, chronic inflammatory cells and numerous multinucleated giant cells. Nevertheless, the cells were devoid of nuclear atypia. A cystic component was not observed. In spite of thorough curettage, the patient suffered from recurrence and severe neurological deficits. A review of the literature revealed no previous cases of solid ABC in the sacrum.

Abstract
Giant-cell tumor is a rare benign tumor that generally arises in long bones of the lower extremity in adults. The involvement of the metacarpal bone in children is extremely rare. The authors report the case of an 8-year-old boy admitted for a painless swelling of the posterior surface of the fourth right metacarpal bone. The radiological examination showed an expansile osteolytic lesion with a multilocular appearance. Total resection of the metacarpal bone and reconstruction with free fibular graft was performed. We highlight the rarity of this neoplasm in childhood and discuss epidemiological, clinical, radiological, and therapeutical characteristics of this pathology.

Abstract
Aneurysmal bone cyst (ABC) is an osseous mass lesion that accounts for 1% of primary bone tumors. We describe 23 cases of ABC initially evaluated by fine-needle aspiration biopsy (FNAB). In 4 cases, the ABC was secondary to another primary tumor. Aspirates from 6 cases (26%) were insufficient. Twelve aspirates diagnosed as ABC by FNAB were confirmed as ABC by histologic examination. The accuracy of FNAB was 82% when cases insufficient for evaluation were excluded. One case diagnosed as ABC cytologically was subsequently found to be metastatic carcinoma. In another, the specimen was interpreted as ABC vs giant cell tumor. In the remainder, a diagnosis of ABC was favored cytologically. Owing to the nonspecific findings, ABC cannot be definitively diagnosed by FNAB. However, the presence of typical clinical and radiographic features in conjunction with a blood-rich, mesenchymal cell containing aspirate devoid of overtly malignant cells strongly suggests the diagnosis of ABC.

Abstract
OBJECTIVES The purpose of this article is to discuss the natural history, treatment, and outcomes for patients with aneurysmal bone cysts (ABC). METHODS Review of the pertinent literature. RESULTS ABCs account for 1% to 2% of all primary bone tumors, usually present in the first 2 decades of life, and exhibit a slight female preponderance. The majority of patients are treated with curettage with local control rates ranging from approximately 70% to 90%. Almost all patients with recurrences are salvaged by one or more additional operations. A small subset of patients is treated with marginal or wide excision and almost all are locally controlled. A few patients with incompletely resectable, aggressive, and/or recurrent ABCs are treated with low-dose (26-30 Gy) radiotherapy (RT) and are locally controlled in approximately 90% of cases. CONCLUSIONS The mainstay of treatment is surgery and most patients are cured with one or more operations. A small subset of patients with incompletely resectable, aggressive, and/or recurrent ABCs may be cured with low-dose RT.

Abstract
The cytologic features in twelve cases of giant-cell tumor (GCT) and five cases of giant-cell tumor of tendon sheath (GCTTS) diagnosed by fine-needle aspiration cytology (FNAC) are described. All of these cases were histopathologically confirmed. The aspirates of GCT are composed of a dual population of mononucleated spindle cell and multinucleated giant cells. The peripheral adherence of giant cells to the spindle cell is the feature of diagnostic significance in GCT. In GCTTS, the aspirate consists of a polymorphic population composed of mononuclear histiocyte-like cells, hemosiderin laden macrophages, foamy macrophages, and a few multinucleated giant cells. FNAC can be used as a diagnostic tool for an early and accurate detection of these two giant cell-rich lesions, since the cytologic features when evaluated in conjunction with the clinical and radiologic features are sufficiently diagnostic.
