OBJECTIVETo investigate surgical methods and therapeutic effects of giant cell tumor of tendon sheath in finger.

METHODSFrom July 2002 to December 2010,70 patients with giant cell tumor of tendon sheath in finger which confirmed by operation and pathology,were retrospectively analyzed. There were 29 males,41 females with an average of 42 years (ranged, 16 to 61), and the course of disease ranged form 4 months to 6 years (mean 11 months). The method of surgery and anesthesia were observed.

RESULTSAll wounds were got stage I healing,no necrosis occurred. Vascular crisis occurred in 6 cases (8.6%), inconformity of diagnosis in 18 cases (25.7%), changing of anesthesia due to situation of tumor in operation in 17 cases (24.3%). The patients were followed up from 2.2 to 10.5 years. Among them, 8 cases (11.4%) recurred, and diagnosied by the second operation without malignant change.

CONCLUSIONThe best anesthesia for giant cell tumor in finger should choose brachial plexus to fully expose,complete resection and less harmful damage; while the operation should complete resection at the stage I, and followed up actively, the second operation can be carried out for recorrenced.

OBJECTIVETo investigate diagnostic methods and surgical effect for the treatment of giant cell tumor of tendinous sheath in wrist.

METHODSFrom September 2002 to October 2009, 8 patients with preoperative diagnosis as giant cell tumor of tendinous sheath based on MRI were treated surgically. There were 5 males and 3 females, ranging in age from 16 to 65 years, with an average of 41 years. The disease course ranged from 10 to 72 months with an average of 31 months.

RESULTSThe diagnosis of all the patients was confirmed as giant cell tumor of tendinous sheath by postoperative pathology. All the patients were followed up, and the during ranged from 5 to 48 months (averaged, 34.2 months). One patient recurred and 3 patients got obvious relief of symptoms of median nerve injury. All the patients had significant improvement in wrist function after surgery.

CONCLUSIONPreoperative MRI is helpful for differential diagnosis of giant cell tumor of tendinous sheath. Thorough removal of tumor is very important in prevention of recurrence.

The localized type of tenosynovial giant cell tumor usually occurs on the palmar side of fingers and toes. Tenosynovial giant cell tumors of the tendon sheath are rarely intra-articular. We report a giant cell tumor of the tendon sheath arising from femoral attachment of the anterior cruciate ligament and its treatment with arthroscopy in a 28-year-old man.

OBJECTIVETo explore the technique of diagnosis and treatment of intra-articular giant cell tumor of tendon sheath (GCTTS) in knee joint, and to evaluate its clinical results.

METHODSTwelve patients with GCTTS treated during 15 years were reviewed. Nine cases were misdiagnosed with meniscus injury (6 cases) and chronic synovitis (3 cases) before operation, only 3 cases were confirmed the diagnosis of GCTTS by MRI. Complete tumorectomy under arthroscope was performed on all 12 cases.

RESULTSThe results of clinical and radiographic followed-up of 9 patients for 1 to 10 years after operation was satisfactory. Clinical symptoms disappeared, range of motion and X-ray findings were normal. There was no recurrent case found.

CONCLUSIONSArthroscopic removal of GCTTS is an effective treatment. Tumor wide resection and debriding the channel which tumor passed through are the key point to prevent the recurrence after operation.

We report the case of a giant cell tumor with diffuse interstitial hemorrhaging and unusually prominent cystic components in the soft tissue of the thigh which has not been reported previously. Magnetic resonance image (MRI), showed signal intensity typical of a giant cell tumor. However, because of its conspicuous large well-circumscribed cystic components, the differential diagnoses, based on the image findings from an ultrasonography (US) and MRI, were complicated epidermoid cyst, cystic change of a neurogenic tumor, and a parasitic cyst.

OBJECTIVES: This study aimed to determine the prevalence of odontogenic cysts, tumors, and other lesions among reports in the archives of the Department of Oral and Maxillofacial Surgery at the Faculty of Dentistry affiliated with Kocaeli University collected over a four-year period.MATERIALS AND METHODS: In this retrospective study, patient records from the archive of the Department of Oral and Maxillofacial Surgery from 2014 to 2018 were reviewed. Patient demographic information (age and sex) and lesion location were recorded and analyzed.RESULTS: From a total of 475 files reviewed, odontogenic cyst was confirmed in 340 cases (71.6%), and odontogenic tumor was confirmed in 52 cases (10.9%). Regarding odontogenic cyst type, the most common was radicular cyst (216 cases), followed by dentigerous cyst (77 cases) and odontogenic keratocyst (23 cases). Among odontogenic tumors, the most frequent was odontoma (19 cases), followed by ossifying fibroma (18 cases) and ameloblastoma (9 cases). Giant cell granuloma was also reported in 35 cases.CONCLUSION: The distribution pattern of odontogenic cysts and tumors in our retrospective study is relatively similar to that reported in the literature. Complete clinical reports for final diagnosis of these lesions and routine follow-up examinations are very important for treatment.
