Arrested pneumatization of the sphenoid sinus is a developmental variant that is not always well recognized and is often confused with other pathologies associated with the skull base. This report describes the case of a patient referred for cone-beam computed tomography (CBCT) imaging for dental implant therapy. CBCT demonstrated a well-defined incidental lesion in the left sphenoid sinus with soft tissue-like density and sclerotic borders with internal curvilinear opacifications. The differential diagnoses included intraosseous lipoma, arrested pneumatization of the sphenoid sinus, chondrosarcoma, chondroid chordoma, and ossifying fibroma. The radiographic diagnosis of arrested pneumatization was based on the location of the lesion, its well-defined nature, the presence of internal opacifications, and lack of expansion. Gray-scale CBCT imaging of the area demonstrated values similar to fatty tissue. This case highlighted the fact that benign developmental variants associated with the skull base share similar radiographic features with more serious pathological entities.

Carcinosarcoma of the parotid gland is extremely uncommon and is known to be an aggressive malignant mixed tumor in which carcinomatous and sarcomatous elements coexist and metastasize together. We report a case of recurrent parotid gland carcinosarcoma that showed squamous cell carcinoma and chondrosarcoma in a 58-year-old woman.

본 연구는 원발성 악성 골종양의 감별진단에 대한 $^{99m}Tc$-MDP 골스캔의 임상적인 유용성을 알아보기 위해 시행하였다. 골조직검사로 원발성 악성골종양으로 진단받았고 골조직검사 전에 $^{99m}Tc$-MDP 골스캔을 하였던 골육종 22예, 연골 육종 5예, 유잉 육종 4예의 총 31예의 환자들을 대상으로 각각의 악성골종양의 공통적인 소견을 관찰하여 이를 방사선학적 검사와 비교하였고, 골육종에서는 조직학적인 간질조직의 형성에 따라 골아세포성, 연골아세포성, 섬유아세포성, 모세혈관 확장성으로 분류하여 골스캔소견과 비교하였다. 골육종에서 공통적인 소견은 강한 방사능 섭취와 동반된 내부의 불규칙한 방사능감소와 골윤곽의 심한 변형으로 22예 중 16예에서 나타났고 조직학적 분류에 따른 차이점은 발견할 수 없었다. 연골 육종에서 공통적인 소견은 정상보다는 증가되었지만 천장관절보다 약한 방사능섭취와 내부의 불규칙한 방사능증가, 비교적 잘 유지된 골윤곽으로 5예중 3예에서 관찰되었다. 유잉 육종에서 공통적인 소견은 천장관절보다 높은 방사능 섭취와 내부의 균일한 방사능 분포, 중등도의 골윤곽 변형으로 4예중 3예에서 관찰되었다. 결론적으로 악성골종양 3예에서 각각 특징적 소견을 나타내는 경향이 있고 환자의 임상적 정보와 방사선학적 소견을 참고하면 감별진단에 도움이 되었다. 그러므로 이에 대한 관심을 갖고 판독하는 것이 중요하다고 생각된다.

견갑관절 주위의 악성종양 치료후의 기능평가를 위하여 저자들은 1991년 1월부터 1993년 12월까지 가톨릭대학교 의과대학 정형외과학 교실에서 견갑관절 주위 악성종양에 대한 수술적 치료를 받은 9례를 분석하여 다음과 같은 결과를 얻었다. 남자 5례, 여자4례이었고, 나이는 최저 22세, 최고 64세로 평균 47세이었다. 연부조직 종양이 2례(MFI, dermatofibrosarcoma protuberance 각각 1례)이었는데, 1례는 forequarter 절단, 1례는 광범위 절제술로 치료하였다. 골종양은 7례(chondrosarcoma 2례, osteosarcoma, MFH, plasmacytoma, thyroid carcinoma metastasis 및 malignant schwannoma 각각 1례)이었는데, 1례는 상완골 근위부 부분절제, 4례는 Malawer분류 제 I-A형의 절제, 1례는 제 I-B형, 1례는 제 V-B형의 절제술을 시행하였다. low grade의 연골육종 1례와 dermatofibrosarcoma protuberance 1례, 갑상선 종양 전이의 1례의 3례를 제외한 6례에서 항암화학요법, 혹은 방사선 요법을 시행하였으며, 1례에서 국소재발이 있었으나 평균 15.3개월 추시된 현재 전례가 생존하고 있다. 골종양 7례증 2례는 관절유합술, 4례는 관절전치환술로 치료하였으며, 관절유합술을 시행한 예와 관절성형술을 시행한 예의 기능은 큰 차이를 보이지 않았다.

The incidence of chest wall tumor is rare than those of other portions of the body. The chest wall tumors need special attention about their diagnosis and management than other tumors. From March, 1985 to September, 1994, 33 patients with chest wall tumor underwent surgical treatment, and those were consisted of 28 benign tumors and 5 malignant tumors arising from soft tissue, rib and sternum.Benign tumors were included 11 lipoma, 4 cysticercosis, 2 chondroma and 1 each of fibroma, dermatofibroma, osteochondroma, fibrous dysplasia and hemangioma,and 6 other cases. Malignant chest wall tumors were included 2 metastatic carcinoma,1 each of giant cell tumor, chondrosarcoma and epithelioid sarcoma.Sex ratio of male to female was 1.5:1, and the range of age was 16 to 72 years,and the mean age was about 40 years. Clinical manifestations of chest wall tumor were palpable mass[55% , pain[21% ,tender mass[9% , growing mass[9% and asymptomatic[9% .The all cases were treated surgically, the results were as follows:Local excision 16 cases, wide resection 12 cases, wide resection with chemotherapy 3 cases, each one case of wide resection with radiotherapy and wide resection with chest wall reconstruction.

Primary malignant bone tumors of the scapula are very rare, and little literature is available regarding their characteristics and outcome. We studied the clinical characteristics, and outcome of patients with primary malignant bone tumors of the scapula. From 1979 to 2008, we treated 7 patients at our institute (4 men and 3 women; chondrosarcoma 3, Ewing's sarcomas 3, Osteosarcoma 1). The mean age was 45 years (range, 5~65 years). The follow-up period was 2 - 180 months. Six patients were performed operations: total scapulectomy 3, partial scapulectomy 1, forequarter resection 1, total resection of the shoulder girdle (Tikhoff-Linberg procedure) 1. No-operative treatment was chosen for one patient with a limited life expectancy. Local recurrence occurred in one patient. Distant metastasis occurred in 3 patients. Of the 7 patients, 4 patients are died because of propagation of the disease. Three patients were alive and apparently disease-free, and these patients were evaluated for functional results with the functional evaluation system of the International Society of Limb Salvage (ISOLAS). Functional result of partial scapulectomy was excellent, however, the function after total scapulectomy or Tikhoff-Linberg procedure is severely impaired. Our study indicates reconstruction procedure needs to be reconsidered following total scapulectomy or Tikhoff-Linberg procedure.

This is a report of 3 cases of tumors, which primarily originated from ribs and the sternum. In the first case of multiple myeloma, the patient was 67 year old male with a tumor located on the middle sternum invading the manubrium and the body of the sternum manifesting symptoms after a contusion of the anterior sternum. The sternum was entirely resected and was replaced by tantalum plate to reconstruct the defective chest wall in order to prevent the paradoxical movement during respiration. In the second case of osteogenic sarcoma, the patient was 43 year old male with a tumor located on the costochondral junction of the left 5th rib for 6 months. The left 5th rib was resected between the middle part and sternochondral junction of it including tumor and adjacent soft tissues. In the third case of chondrosarcoma, the patient was 36 year old male with a tumor located near the posterior angles of the right 7th and 8th ribs manifesting back pain on the area where the tumor was located. Resection of right lower lobe was performed since direct invasion of tumor was seen in the superior segment of right lower lobe. This was followed by the resection of both 7th and 8th ribs at the area between the costovertebral junction and the portion 10 em apart from the tumor including the tumor and intercostal soft tissues. Diagnoses of 3 cases of tumors described above were confirmed by histopathologic examination postoperatively. The postoperative courses were uneventful.

Aspiration of lytic bone lesions is an excellent diagnostic test in the initial evaluation of primary bone tumor. However, cytologically, it can be difficult to differentiate osteosarcoma (OSA) from other bone neoplasms, including fibrosarcoma, chondrosarcoma, synovial cell sarcoma, malignant fibrous histiocytoma and malignant peripheral nerve sheath tumor. The purpose of this study is to introduce alkaline phosphatase (ALP) staining to differentiate OSA from other mesenchymal tumors. Tumors actively producing bone are specifically positive for ALP staining. Unstained, cytologic specimens were incubated for 10 minutes with nitroblue tetrazolium chloride/5-bromo-4-chloro-3-indolyl phosphate toluidine salt-phosphatase substrate. Among 20 cases of cytology specimen, 14 were positive for ALP staining and histopathology, 6 were negative for ALP staining and histopathology. ALP staining was 100% sensitive and specificity for the diagnosis of OSA. Aspirate cytology with ALP staining was a simple, fast, safe and accurate diagnostic test for the evaluation of suspected OSA lesions in dogs.

An osteochondroma is an osseous protuberance with cartilaginous growth potential, usually arising in skeletal bone and relatively uncommon in the craniofacial bone. Osteochondroma of the craniofacial region usually occurs at the condyle or the tip of the coronoid process, and rarely arises in the mandibular body, symphysis, ramus, and similar areas. Excision of the lesion including the periosteum is curative, and recurrence or malignant change (usually to a chondrosarcoma) after treatment is rare. We present an atypical case of osteochondroma in the left mandibular inferior border with review of literature.
