ABSTRACT
Teratocarcinosarcoma rinosinusal es una neoplasia maligna infrecuente y rara, que combina elementos de teratoma y carcinosarcoma. Se compone de epitelio benigno o maligno (fibroblastos), mesénquima (cartílago, hueso o músculo liso) y elementos neurales. Hasta el año 2008 se han reportado un total de 63 casos de ubicación rinosinusal. Presentamos el caso de un teratocarcinosarcoma de fosa nasal, en un hombre de 67 años de edad, que consultó por obstrucción nasal rápidamente progresiva. La lesión se resecó completamente por abordaje endoscópico. El diagnóstico fue confirmado por histopatología e inmunohistoquímica. Se realizó tratamiento complementario con radioterapia, sin evidencia de recidiva al año después de la cirugía.
Rhinosinusal teratocarcinosarcoma is a rare malignant neoplasm, which combines teratoma and carcinoma elements. It is composed of benign or malignant epithelium (fibroblasts), mesenchymatic (cartilage, bone or smooth muscle) and neural elements. Until 2008, a total of 63 cases of rhinosinusal location have been reponed. We present the case of a nasal cavity teratocarcinosarcoma ín a 67 year old man that presented with rapidly progressing nasal obstruction. The lesion was completely resected by endoscopic approach. Diagnosis was confirmed by histological pathology and immunohistochemistry Additional treatment by radiotherapy was administered, with no evidence of recurrences a year after surgery.

Upper gastrointestinal bleed as the first symptom of metastatic testicular tumors is rare. We describe a 17-year-old man who presented with upper gastrointestinal bleed; endoscopic fine needle aspiration cytology from a duodenal mass suggested germ cell tumor, which was later confirmed on histology of the testis.
