Recurrence of atypical fibroxanthoma. Diagnosis and treatment

Introduction: The soft tissue sarcomas (SPM) accounts for only 1% of malignant tumors of the adult population. The SPM is the most frequent malignant fibrous histiocytoma (MFH) that exhibits behavior characterized by the tendency to invasion of adjacent tissue and metastatic spread early. One of its variants is the atypical fibroxanthoma (FA). Objective: To describe a case of probable recurrence of AF underwent surgical treatment and presentation of a literature review. Case report: Patient female, 63 years, presenting with a mass in the face about four inches and a history of prior resection of the lesion in the same topography. The patient underwent surgical resection with a diagnosis of AF. Conclusion: The FA is a rare tumor histological diagnosis difficult. The correct histological diagnosis and patient follow-up are essential...

Endoscopic treatment of esthesioneuroblastoma / Abordagem endoscópica de estesioneuroblastoma

Esthesioneuroblastoma is an uncommon malignant tumor of the nasal vault. Treatment consists of craniofacial resection. As endoscopic techniques have advanced, this approach has been recommended to avoid morbidity and to reduce costs. AIM: To evaluate outcomes in patients with esthesioneuroblastoma treated by an endoscopic technique. METHODS: A prospective study of patients diagnosed with esthesioneuroblatoma and treated by an endoscopic technique. The literature over the past 20 years was reviewed for an update on the pathology. RESULTS: We present 4 patients, 3 males and 1 female, staged according to Kadish and Dulguerov. All were treated surgically with endoscopic techniques, followed by radiotherapy. One patient was also submitted to neck dissection and chemotherapy because of regional metastasis. There were no significant postoperative complications. The mean hospital stay was 3 days; one patient stayed in the ICU for 24 hours after surgery. Follow-up is recent; so far there are no recurrences. CONCLUSION: Esthesioneuroblastoma is a potentially curable malignancy. Endoscopic techniques help reduce hospital costs and decrease the morbidity. Adequate margins of healthy tissue are obtained with endoscopic resection, as with craniofacial resection. The literature suggests that outcomes after endoscopic resection are similar to those of the conventional external approach.

Estesioneuroblastoma é uma neoplasia incomum de linhagem epitelial. Seu tratamento convencional baseia-se na ressecção craniofacial. Técnicas endoscópicas tem sido preconizadas em sua terapia com o intuito de diminuir morbidades e custos. OBJETIVO: Relatar a experiência na abordagem terapêutica do tumor com uso de endoscópio. MATERIAL E MÉTODO: Estudo prospectivo de pacientes com diagnóstico de Estesioneuroblastoma submetidos a tratamento endoscópico. Fez-se revisão de publicações relacionadas ao tumor. RESULTADOS: Apresentamos quatro pacientes, sendo 3 homens e 1 mulher, estadiados de acordo com Kadish e Dulguerov. Foram submetidos a ressecção endoscópica com margem e terapia adjuvante (radio ou quimioterapia). Não se observaram complicações pós-operatórias significativas. O tempo médio de internação foi 3 dias e um paciente permaneceu em observação no CTI por 24 horas. O seguimento é recente e não há relato de recidivas. CONCLUSÃO: Estesioneuroblastoma é um tumor maligno potencialmente curável. O uso da técnica cirúrgica endoscópica nasal traz consigo menor morbidade ao paciente (período de internação e tempo cirúrgico menor) e custos hospitalares diminuídos. Possibilita a ressecção da neoplasia com margens comparáveis à cirurgia convencional. Os resultados em longo prazo descritos na literatura são semelhantes ao tratamento convencional. Nosso seguimento ainda é recente para concluir algo sobre prognóstico.
