Background: A solid pseudopapillary pancreatic tumor is an epithelial tumor of low malignancy that primarily affects young women; it represents ~1-2% of all pancreatic neoplasms. Its presentation in males is extraordinary. Clinical case: A 23-year-old male with six months' symptomatology with early satiety, postprandial abdominal distension, and occasional colic pain. In the physical examination, an abdominal mass was located in the mesogastrium; it was confi rmed with ultrasound and tomography, dependent on the pancreas. He underwent surgery and was diagnosed as a solid pseudopapillary tumor. The patient presented diabetes mellitus as a complication; he was treated by an endocrinologist, without other morbidities. Conclusions: Solid pseudopapillary tumor of the pancreas is a rare neoplasm. It is extraordinary in males. Clinical manifestations include abdominal pain, sensation of plenitude or early satiety, abdominal mass, nausea and vomiting, but the patient may be asymptomatic. Computerized axial tomography is the main diagnostic method, where a large encapsulated heterogeneous mass can be observed. Diagnosis is established through biopsy; surgery is the best treatment, with 97% of survival at fi ve years.

tibia proximal. Avances recientes en implantes y en las técnicas quirúrgicas han hecho que esta opción sea preferible a la amputación para muchos pacientes. La supervivencia a largo plazo y las tasas de recurrencia son similares entre el salvamento y la ablación de la extremidad. Caso clínico: Femenino de 55 años con dolor de seis meses de evolución en tercio superior de pierna izquierda a 2 cm por debajo de tuberosidad tibial y aumento de volumen en dicha zona, con estudios de imagen y biopsia se confirma osteosarcoma, sin metástasis; se realiza resección de la tibia proximal y reconstrucción endoprotésica. Conclusiones: La resección de la tibia proximal con reconstrucción protésica puede estar asociada con complicaciones significativas; sin embargo, éstas pueden minimizarse con planificación preoperatoria adecuada y una técnica meticulosa.
