  • Giant cell tumors are primary bone tumors originating from non-osteoblastic connective tissue. The sites of involvement were commonly distal femur, proximal tibia, proximal humerus, distal radius and others (including os calcis, ilium and sacrum). Giant cell tumor located around knee joint has been difficult to treat because of local recurrence following curettage with or without bone graft. Although primary resections reduce recurrence of the lesion, the joint function will be markedly impaired. Marginal excision was very often complicated by a loss of joint integrity since all the giant cell tumors occupy juxtaarticular positions. Techniques involving physical adjuncts(high speed burr and electric cauterization) have been used in the hope of decreasing the rate of local recurrence and avoiding the morbidity of primary resection. A meticulous clinical, radiological and histological evaluation is needed to choose the correct treatment, keeping in mind the possibility of recurrence after each treatment modality.

  • 거대세포형 골육종은 드문 종양으로 거대세포종과의 구분이 어렵다. 이들 종양은 발생 부위 및 방사선학적 소견이 동일하다. 또한 이들 종양의 조직학적 소견도 구분이 어렵다. 이들 두 종양의 서로 다른 예후와 치료 방법 때문에 처음 진단시 반드시 정확한 진단을 내려야 한다. 본 논문은 처음 진단 당시 침생검에 의해 거대세포종으로 진단되었던 경골 근위부의 거대세포형 골육종의 증례를 보고하는 바이다.

  • Purpose: This study aimed to investigate the computed tomography and magnetic resonance imaging features of giant cell tumors in the temporomandibular joint region to facilitate accurate diagnoses. Materials and Methods: From October 2007 to June 2020, 6 patients (2 men and 4 women) at Yonsei University Dental Hospital had histopathologically proven giant cell tumors in the temporomandibular joint. Their computed tomography and magnetic resonance imaging findings were reviewed retrospectively, and the cases were classified into 3 types based on the tumor center and growth pattern observed on the radiologic findings. Results: The age of the 6 patients ranged from 25 to 53 years. Trismus was found in 5 of the 6 cases. One case recurred. The mean size of the tumors, defined based on their greatest diameter, was 32 mm (range, 15-41 mm). The characteristic features of all cases were a heterogeneously-enhancing tumorous mass with a lobulated margin on computed tomographic images and internal multiplicity of signal intensity on T2-weighted magnetic resonance images. According to the site of origin, 3 tumors were bone-centered, 2 were soft tissue-centered, and 1 was peri-articular. Conclusion: Computed tomography and magnetic resonance imaging yielded a tripartite classification of giant cell tumors of the temporomandibular joint according to their location on imaging. This study could help clinicians in the differential diagnosis of giant cell tumors and assist in proper treatment planning for tumorous diseases of the temporomandibular joint.

  • Purpose: Giant cell tumors of the bone are rare, locally aggressive lesions that primarily affect the epiphysis of the long bones in young adults. These tumors occur very rarely on the skull, principally in the sphenoid and temporal bones. The occipital bone is an unusual site. We report a rare case of a giant cell tumor of the occipital bone with a review of the relevant literature. Methods: A 7-year-old boy presented with a mass of the right occipital area, which was accompanied by localized tenderness and mild swelling. The mass was first recognized approximately 1 year earlier and grew slowly. There was no significant history of trauma. The physical examination revealed a nonmobile and non-tender bony swelling on the occipital region. The neurological evaluation was normal. The serial skull radiography and CT scan showed focal osteolytic bone destruction with a bulged soft tissue mass in the right occipital bone. The patient underwent a suboccipital craniectomy and a complete resection of the epidural mass. The lesion was firm and cystic. The mass adhered firmly to the dura mater. Results: The postoperative clinical course was uneventful, and the patient was discharged 5 days later. The histopathology report revealed scattered multinucleated giant cells and mononuclear stromal cells at the tumor section, and the giant cells were distributed evenly in the specimen, indicating a giant cell tumor. Conclusion: Giant cell tumors are generally benign, locally aggressive lesions. In our case, the lesion was resected completely but a persistent long term follow up will be needed because of the high recurrence rate and the possible transformation to a malignancy.

  • A primary giant cell tumor of the rib is very rare. The most common site of a giant cell tumor arising from the rib is the posterior arc. A giant cell tumor arising from the anterior arc of the rib is extremely rare. The treatment of a giant cell tumor of the rib is not well defined. Generally, a complete surgical resection is performed in a patient with a primary giant cell tumor of the rib. We report a case of a giant cell tumor arising from the anterior arc of the rib that was treated with a wide excision and chest wall reconstruction.

  • 척추의 거대 세포종은 진단이 어려운 경우가 많고, 고도의 악성도로 인해서 수술이 불가능한 경우가 많다. 척추의 거대 세포종은 높은 재발율과 함께 척수의 기계적 압박 가능성으로 인해 방사선 치료가 근간이었으나, 최근에는 근치적 절제술과 함께 기구를 이용한 전후방 고정술을 시행 하여 좋은 결과를 보고 하고있다. 본 정형외과학교실에서는 경부 동통을 유발하며 제3경추를 침범한 거대세포종에 대해서 근치적 절제술과 함께 후방 기기술을 통한 융합을 시행 하였으며, 추시 관찰상 우수한 치료 결과를 보였기에 문헌 고찰과 함께 보고하는 바이다.

  • Malignant tumors of the breast with stromal multinucleated giant cells are rare entity of uncertain clinical significance. There have been few reports on the fine needle aspiration cytologic(FNAC) findings about these rare tumors. We report a FNAC case of invasive mammary carcinoma with osteoclast-like giant cells not only for its rare occurrence but in particular for its distinctive cytologic picture on aspirated material. The patient was a 40-year-old woman who presented with a right breast mass for one month. Mammography showed a well-demarcated rounded mass density without calcification. The aspirates of FNAC were highly cellular and two main cell types were seen; malignant epithelial cells and osteoclast-like multinucleated giant cells. The carcinoma cells occurred singly or arranged in loose clusters with ill-defined cytoplasm, oval nuclei, coarse chromatin and small but distinct nucleoli. The multinucleated giant cells showed variable number of nuclei with prominent nucleoli and abundant dense oxyphilic cytoplasm. The immunocytochemical studies suggested that osteoclast-like giant cells were not of epithelial origin, but rather of histlocytic origin.

  • 골조직에 발생하는 거대세포종은 국소적으로는 양성이지만 재발률이 매우 높고, 아주 드물게 원격전이를 일으킬 수 있다. 우측 요골에 발생한 거대세포종이 치료 후 재발되어, 요골을 제거한 후, 다시 동측 흉벽 연부조직에 전이된 29세의 남자환자를 보고하는 바이다. 종양은 흉벽의 골조직과는 연관이 없었다. 수술은 주위 연부조직과 함께 광범위 절제하였으며, 조직학적 검사상 악성 종양을 시사하는 소견은 없었다.
