Chondrosarcoma is a malignant tumor that arises from cartilage. In the maxillary area, the tumors spread locally but may also invade blood vessels and metastasize systemically. Initial surgical resection is the treatment of choice.

Chondrosarcoma is the most common mesenchymal tumor of the larynx and approximately 200 cases have been collected in the world medical literature. It is less aggressive in the larynx than elsewhere: cervical or distant metastases are rare (8.5%), and although local recurrences are not uncommon, they are not catastrophic. A retrospective study was made on eight cases of laryngeal chondrosarcoma. Three cases had originally been diagnosed as idiopathic vocal cord paralysis, possibly because of early involvement of the cricoarytenoid joint or the distal portion of the recurrent nerve. This fact emphasizes the need for accurate laryngeal computed tomography in cases of vocal cord paralysis of unknown origin. Surgical excision is the treatment of choice for laryngeal chondrosarcoma, and conservative techniques may sometimes be appropriate. Supraglottic laryngectomy may be the technique of choice in the rare cases of epiglottic involvement.

Chondrosarcoma is a slow-growing malignant tumor, with a mainly local infiltration, usually arising from skeletal cartilaginous cells. However, a few such neoplasms also arise from extraskeletal mesenchymal cells. Metastasis are usually seen with undifferentiated tumors (grade III), mainly within the lungs. The best treatment associates total surgical resection with chemotherapy. Radiotherapy is of poor use. Isolated pulmonary metastasis can be profitably withdrawn. Prognosis is about of 75% of survival after 10 years, in case of well-differentiated tumors (grade I). The prognosis is far worse for undifferentiated tumors (grade III), turning around 10% of survival after 10 years.

Chondrosarcoma of the epiglottis is extremely rare and there are no previously reported cases of this neoplasm with regional or distant metastases. The first case of this entity and its histopathologic considerations are presented. Accurate grading of this malignancy is essential, since a more poorly differentiated pathologic condition in these tumors indicates aggressive biologic properties consequently leading to frequent local recurrences and metastasis. This is evident in the present case in which, despite being free of local or regional recurrence for 3 years following a supraglottic laryngectomy and bilateral neck dissections, the patient developed pulmonary metastases. We support the use of conservative laryngeal surgery and modified neck dissections for this disease rather than partial resections or debulking procedures, since the histopathologic condition may not be fully recognized without microscopic analysis.

Chondrosarcoma of the larynx is a rare neoplasm. The characteristic features of this tumor are described, and a case in a 69-year-old woman is reported. This case demonstrates the difficulties of histological classification. On the first biopsy specimen a benign chondroma was diagnosed. However, the microscopical features of the excised tumor were those of a chondrosarcoma. It is generally accepted that radiotherapy is of no value; surgical treatment by laryngectomy is advised. Some authors recommend a conservative attitude towards these tumors, which are of low malignancy, the growth slow and the risk of local or distant metastases slight.

Chondrosarcoma is rare in children. Only 12 patients with a diagnosis of chondrosarcoma were treated at Children's Hospital Medical Center in Boston during the period from 1957 to 1980. Pediatric chondrosarcoma has a relatively rapid onset, manifested by pain, a palpable mass and neurological symptoms with the lesion localized in the spinal column. The pelvis was the most frequent location. Ten patients had primary and two patients had secondary chondrosarcoma. Of the latter two, one developed chondrosarcoma in a preexisting osteochondroma and the other had irradiation for neuroblastoma. The poorest outcomes were in patients who had involvement of the pelvic girdle and spinal column. Grade 2 and 3 lesions had the worst prognoses with metastases occurring within 12 months. Eight patients died at the time of study, and the longest survival time was 80 months. If surgically feasible, the treatment is radical excision. Radiation therapy and chemotherapy should be reserved for recurrences or distant metastasis.

Chondrosarcoma of the larynx is an uncommon, slow-growing malignant tumor of the larynx which tends to metastasize late. This paper adds to the literature a case which was followed for 18 years. During the first three years it was thought to be a benign chondroma. Conservative management by limiting surgical resection, at the patient's direction, allowed observation of the disease for this unusual length of time. Massive enlargement finally necessitated laryngectomy. The lesion, though unquestionably malignant, had not infiltrated adjacent neck structures and appears to have been totally excised, with the patient now being free of disease six months after surgery. This supports the view of conservative surgical management.

The authors present a retrospective analysis of 59 chondrosarcoma patients treated at the Norwegian Radium Hospital during the period 1981 to 1993. 31 patients were admitted with untouched tumour, seven after fine needle cytology and 20 after open biopsy or partial excision. One patient had recurrent local disease. Only 20% of the tumours were of high grade malignancy. 51 patients were treated by surgery. Reconstructions were performed in 16 patients, using allografts or endoprostheses. Amputations were performed in six cases and wide excision in 12 cases. In these 18 patients local recurrence appeared in one case, and two developed lung metastases. Only one of the 18 patients operated by amputation or wide excision has since died from chondrosarcoma. Marginal excisions were performed in 26 cases. Nine of these patients developed a local recurrence, five developed metastases and three have died. Six patients had partial excisions. Postoperative radiotherapy was given to one patient only. Five of the six are alive. In one case, the quality of the margins could not be evaluated. A total of 45 of the 51 patients treated for the primary tumour by surgery are alive. The median observation time is four years. Treatment of nonmetastatic chondrosarcoma should be surgical. Chondrosarcoma patients show wider variations in age, localization of tumour and tumour growth rate than patients with other bone sarcomas. Although wide excisions provide the best local control of any grade of malignancy, the mutilation or risk involved may be so great that some patients may benefit from marginal or even partial excision.

We evaluated the diagnostic accuracy of fine-needle aspiration biopsy in a prospective study of 300 patients with previously undiagnosed bone lesions. Patients with suspected local recurrence of a primary bone tumour or a metastatic lesion of a previously diagnosed malignancy were excluded. Fine-needle aspiration biopsy was performed under radiological control as an outpatient procedure. The series was grouped into three major categories: 1) benign bone lesions including infections; 2) primary malignant bone tumours; and 3) metastases including lymphomas and myelomas. We compared the cytological diagnosis with the final diagnosis as assessed by histological examination and/or the clinical and radiological features. Material considered conclusive for cytological diagnosis was obtained from 251 of the 300 patients. Of the 49 failures, there were 24 aspirates with insufficient cellular yield and 25 in which a diagnosis could not be made although the cytological material was adequate in quantity. Most of the inconclusive aspirates (36/49) were obtained from benign bone lesions. The diagnosis was correct in 239 (95%) of the 251 cases providing adequate cytological material. There were eight (3%) falsely benign diagnoses, one (0.3%) falsely malignant, and three cases in which we were unable to differentiate between sarcoma and a metastasis. Chondrosarcoma (2/12) gave the greatest diagnostic difficulty and Ewing's sarcoma the least (0/9). There were no decisive errors of treatment. All falsely benign or malignant diagnoses were questioned, and led to open biopsy since they did not correlate with the clinical and radiological features. Our study suggests that fine-needle aspiration biopsy is a valid option for the diagnosis of bone tumours. It is a simple outpatient procedure which gives sufficient cytological material for the correct diagnosis in 80% of cases. As with histological analysis of material from open biopsy, the cytological assessment must agree with the clinical and radiological findings.

Chondrosarcoma is the most common nonepithelial sinonasal neoplasm in the dog, and metastasis is considered rare. A 7-year-old Irish Setter had bilateral renal enlargement 17 months following surgery and radiotherapy for a primary nasal chondrosarcoma. Histologic evaluation revealed chondrosarcoma metastases in both kidneys. A diagnosis of nasal chondrosarcoma with bilateral renal metastasis was made. The clinical importance of this report is that routine recommendations for the evaluation of regional and/or distant metatasis in a dog with a dignosis of nasal chondrosarcoma, namely routine whole body physical examination and thoracic radiography, failed to demonstrate the presence of abdominal metatases, which ultimately led to the demise of this dog. The biologically aggressive nature of this chondrosarcoma of the nasal cavity indicates that additional information is needed before a prognosis can be reliably established for dogs with this tumor type.
