    Giant-cell tumors of the tendon sheath involving the hand or the wrist: an analysis of 141 patients; [El ve el bileginde tendon kilifinin dev hücreli tümörü: 141 hastanin degerlendirilmesi.]
    (2004) Ozalp T.; Yercan H.; Kurt C.; Ozdemir O.; Coşkunol E.
    OBJECTIVES: Giant-cell tumors of the tendon sheath localized in the hand or wrist were retrospectively reviewed with respect to diagnosis, surgical treatment, and postoperative complications. METHODS: During a 21-year period, a total of 141 patients (83 females, 58 males; mean age 37.5 years; range 6 to 77 years) underwent surgery for 146 lesions that developed in the hand (n=134) or the wrist (n=12). Involvement was on the right side in 77 patients, and on the left side in 64 patients. The mean follow-up period was 3.5 years (range 6 months to 11 years). RESULTS: On presentation, the most common symptom was the presence of a painless soft tissue mass. The most frequent localization was the volar part (76%) of the second (27%) and the third (24) fingers, or the proximal phalanx (57%). Forty per cent of tumors were encountered at ages between 30 and 50 years. The duration of symptoms ranged from one month to five years and the highest number of presentations fell within the first six months. In eighteen patients, radiologic studies showed osseous involvement, being cortical sclerosis in 12 patients, and erosion in eight patients. Postoperative complications included digital nerve injuries in four patients, superficial infection in three patients, and joint stiffness in 12 patients. Twenty-three patients (16%) developed recurrences within a mean of 3.7 years (range 2 months to 7 years). CONCLUSION: Taking high rates of recurrences into consideration, surgery for giant-cell tumors of the tendon sheath requires wide surgical exposure, attentive skills, and the use of magnification.

    Synovial hemangiohamartomas of the knee joint
    (2007) Yercan H.S.; Okcu G.; Erkan S.
    Hemangioma or vascular malformation of the synovium is rare and presents a difficult problem in diagnosis and treatment. A long history of joint pain and recurrent non-traumatic hemarthrosis usually draws attention to the hemangioma of the knee joint. The lesion can be seen in two different formations; the synovial hemangioma or the arteriovenous malformation named as hemangiohamartomas, both of which involve the synovium and cause non-traumatic episodes of hemarthrosis. MRI scanning together with arthroscopy is a diagnostic tool to demonstrate the extent and the nature of the lesion. We treated the three patients at different ages. All patients underwent standard radiographic examination, CT scans, MRI and diagnostic arthroscopy. After frozen section taken via arthroscopically, the lesions were excised by arthrotomy. The mean follow-up was 38 months (31-45) and all patients are asymptomatic postoperatively. Three additional cases and a review of the literature are presented because of the rarity of the lesion. © Springer-Verlag 2006.

    Tumor-like Lesions of Bone and Soft Tissues and Imaging Tips for Differential Diagnosis
    (Thieme Medical Publishers, Inc., 2020) Örgüç S.; Arkun R.
    In the musculoskeletal system, tumor-like lesions may present similar imaging findings as bone and soft tissue tumors and can be defined as tumors on radiologic examinations. Misinterpretation of the imaging findings can lead to inappropriate clinical management of the patient. There is still some debate regarding the pathophysiology and origin of tumor-like lesions that include congenital, developmental, inflammatory, infectious, metabolic, reactive, posttraumatic, post-therapeutic changes, and some miscellaneous entities causing structural changes. Although tumor-like lesions are historically defined as non-neoplastic lesions, some of them are classified as real neoplasms. We discuss a spectrum of entities mimicking tumors of bone and soft tissues that include various non-neoplastic diseases and anatomical variants based on imaging findings. © 2020 BMJ Publishing Group.

    Soft tissue tumor imaging in adults: European Society of Musculoskeletal Radiology-Guidelines 2023—overview, and primary local imaging: how and where?

    Objectives: Early, accurate diagnosis is crucial for the prognosis of patients with soft tissue sarcomas. To this end, standardization of imaging algorithms, technical requirements, and reporting is therefore a prerequisite. Since the first European Society of Musculoskeletal Radiology (ESSR) consensus in 2015, technical achievements, further insights into specific entities, and the revised WHO-classification (2020) and AJCC staging system (2017) made an update necessary. The guidelines are intended to support radiologists in their decision-making and contribute to interdisciplinary tumor board discussions. Materials and methods: A validated Delphi method based on peer-reviewed literature was used to derive consensus among a panel of 46 specialized musculoskeletal radiologists from 12 European countries. Statements were scored online by level of agreement (0 to 10) during two iterative rounds. Either “group consensus,” “group agreement,” or “lack of agreement” was achieved. Results: Eight sections were defined that finally contained 145 statements with comments. Overall, group consensus was reached in 95.9%, and group agreement in 4.1%. This communication contains the first part consisting of the imaging algorithm for suspected soft tissue tumors, methods for local imaging, and the role of tumor centers. Conclusion: Ultrasound represents the initial triage imaging modality for accessible and small tumors. MRI is the modality of choice for the characterization and local staging of most soft tissue tumors. CT is indicated in special situations. In suspicious or likely malignant tumors, a specialist tumor center should be contacted for referral or teleradiologic second opinion. This should be done before performing a biopsy, without exception. Clinical relevance: The updated ESSR soft tissue tumor imaging guidelines aim to provide best practice expert consensus for standardized imaging, to support radiologists in their decision-making, and to improve examination comparability both in individual patients and in future studies on individualized strategies. Key Points: • Ultrasound remains the best initial triage imaging modality for accessible and small suspected soft tissue tumors. • MRI is the modality of choice for the characterization and local staging of soft tissue tumors in most cases; CT is indicated in special situations. Suspicious or likely malignant tumors should undergo biopsy. • In patients with large, indeterminate or suspicious tumors, a tumor reference center should be contacted for referral or teleradiologic second opinion; this must be done before a biopsy. © The Author(s) 2023.
