The incidence of neck recurrence after selective neck dissection was 4.5%, and it occurred either inside (57.1%) or beyond (42.9%) the limits of the selective neck dissection.
J Bras Patol Med Lab • v. 41 • n. 2 • p. 125-9 • abril 2005 y unitermos key words resumo O sarcoma de células dendríticas foliculares (SCDF) é uma neoplasia maligna rara que envolve linfonodos e sítios extranodais. Pode exibir variado aspecto histológico e comportamento clínico, mas usualmente apresenta um curso agressivo. Relatamos um caso de sarcoma de células dendríticas foliculares em um paciente de 37 anos de idade, do sexo masculino, em topografia de tonsila palatina esquerda, que se apresentava como abaulamento e edema em trígono retromolar esquerdo. O exame clínico evidenciou lesão tumoral ulcerada e o estudo tomográfico mostrou lesão bem delimitada em região parafaríngea à esquerda. Foi submetido a duas biópsias incisionais que foram inconclusivas, sendo então realizada ressecção cirúrgica da lesão com ampliação para a tonsila palatina esquerda adjacente. O estudo histopatológico do espécime revelou neoplasia maligna constituída por proliferação de células fusiformes, e o estudo imuno-histoquímico confirmou o diagnóstico. O SCFD deve ser considerado no diagnóstico diferencial de qualquer neoplasia de células fusiformes com infiltrado inflamatório crônico de permeio surgindo em região de cabeça e pescoço. Esta lesão exibe padrões histológicos peculiares que permitem um diagnóstico presuntivo, sendo que o diagnóstico final requer confirmação através de métodos especiais. Sarcoma Célula dendrítica folicularLinfonodos abstract Follicular dendritic cell sarcoma (FDCS) are uncommon malignant neoplasms that can involve lymph nodes or extranodal sites. They can exhibit a broad spectrum of histologic appearences and behavior, but usually pursue an aggressive course. A case of follicular dendritic cell sarcoma arised in the tonsil region is reported in a 37-year-old man. He had a swelling in the left retromolar trigone. Clinical examination disclosed an ulcerated mass. CT scans showed a low density lesion in the left medial parapharyngeal area. The biopsy specimen was insatisfatory and the patient underwent successful surgical excision of the tumor which was extended to palatine tonsil adjacent and right palatine tonsil. The specimen revealed a low grade malignant tumor and immunohistochemical has confirmed the diagnosis. FDCS should be considered in the differential diagnosis of any spindled cell tumor with interspersed chronic inflammatory cells occurring in head and neck regions . This tumor exhibits distinctive histologic features that permit its presumptive diagnosis, but a final diagnosis requires confirmation with special studies.

20502 Background: Pulmonary metastasis from Osteosarcoma occurs in 30% to 40% of cases. Chemotherapy and surgical resection are the current preferred options for these patients, although overall outcome remains poor, with few patients achieving long term overall survival. Prognostic factors for better selecting these patients are needed. Methods: We reviewed the survival and the prognostic factors from 88 consecutive patients with pulmonary metastasis from osteosarcoma, submitted to metastasectomy at a single institution. Clinical and demographic variables, related to the primary tumor as well as to the pulmonary metastases and treatment procedures were registered. Univariate ( Log-rank and Breslow tests) and multivariate analysis (Cox-regression) were performed to identify significant prognostic factors related to overall survival. Results: Median follow-up time was 34 months, and 12.5% were alive without disease, 14.8% were alive with disease, 58% were dead of disease, 1,1% were dead from other causes, and 14.8% were lost to follow-up. The overall 5- year survival was 19%. Disease free interval (DFI), number of thoracotomies and complete resection at last thoracotomy were significant prognostic factors at univariate analysis. Median survival from first thoracotomy for patients with DFI = 12 months was 24.6 months, compared to 9.6 months for DFI < 12 months (p= 0.0014). Complete resection at last thoracotomy significantly improved median overall survival (19.1 versus 9.6 months) (p=0.0117). Cox-regression analysis showed only disease free interval more than 12 months (p=0.014) and complete resection at last thoracotomy (p=0.003) to be independent significant prognostic factors. Sex, age, site and stage of primary tumor, number of lung nodules, bilateral nodules, and chemotherapy treatment for lung metastases did not significantly impact on survival. Conclusion: Disease free interval and complete resection at last thoracotomy are significant prognostic factors for patients with resected pulmonary metastasis from osteosarcoma.
