Síndrome de Doege-Potter: hipoglicemia secundaria a tumor fibroso solitario de la pleura / Doege-Potter syndrome: hypoglycemia secondary to solitary fibrous tumor of the pleura. Report of one case

Doege-Potter syndrome is characterized for hypoglycemia associated with solitary pleural fibrous tumors. We report a 38-year-old woman with a history of weight loss, malaise and edema. After an episode of symptomatic hypoglycemia, she was admitted to the hospital, where she had new episodes of hypoglycemia. A Chest X ray and scan showed a right pleural tumor that was surgically excised. After surgery the episodes of hypoglycemia subsided. The pathological study of the tumor revealed a solitary fibrous pleural tumor. After 15 months of follow up, the patient is symptom free and without evidence of tumor relapse.

Resección quirúrgica de plasmocitoma solitario del esternón asociado a cirugía de revascularización miocárdica: seguimiento a largo plazo / Surgical resection of solitary plasmacytoma of the sternum associated with coronary artery bypass grafting surgery: long-term follow up

The plasmacytomas tumors are caused by a malignant proliferation of plasma cells. Primary tumors of the sternum are uncommon, being this kind of tumors exceptional. We present the case of a 72 years old man with a sternal plasmacytoma, that after 2 years of receiving radiotherapy treatment, had tumor growth, associated with coronary artery disease. In this case, surgical resection of solitary sternal plasmacytoma was performed associated with coronary artery bypass grafting surgery. The chest wall reconstruction was done with a polypropylene mesh. More than 5 years long-term follow up was completed and the patient is asymptomatic and free of malignant proliferation of plasma cells.

Los plasmocitomas son tumores originados por una proliferación neoplásica de células plasmáticas. Los tumores primarios de esternón son infrecuentes, siendo los plasmocitomas solitarios de esternón excepcionales. Presentamos el caso de un hombre de 72 años con un plasmocitoma esternal que después de 2 años post tratamiento con radioterapia presentó aumento de tamaño tumoral asociado a enfermedad coronaria. Se realizó resección quirúrgica del plasmocitoma solitario del esternón asociada a cirugía de revascularización miocárdica con 4 bypass coronarios. La pared torácica fue reconstituida con una malla de polipropileno. A más de 5 años de seguimiento el paciente se encuentra asintomático cardiovascular y libre proliferación maligna de células plasmáticas.

Cuerpo extraño intratorácico post traumatismo penetrante / Thoracic foreign body after penetrating chest trauma

We present the case of a 21 year old man with an intra thoracic foreign body after penetrating chest trauma. The foreign body was the blade of a knife. It was removed through the wound, without thoracotomy or video-assisted thoracic surgery (VATS) and the patient evolved without incidents. Intra-thoracic foreign bodies secondary to penetrating trauma are rare. They are usually removed through thoracotomy or VATS. Both alternatives allow adequate exploration of the intra-thoracic structures and repair injuries that are potentially lethal. In stable patients and selected cases, they can be removed without surgery (without thoracotomy or VATS); always in an operating room and under general anesthesia, in case that surgical exploration could be needed after the procedure.

Presentamos el caso de un hombre de 21 años con un cuerpo extraño intra torácico post traumatismo penetrante. El cuerpo extraño que correspondía a la hoja de un cuchillo, fue extraído a través de la misma herida traumática, sin toracotomía ni cirugía torácica video asistida (VATS). El paciente evolucionó favorablemente. Los cuerpos extraños intra torácicos secundarios a un traumatismo penetrante son infrecuentes. Se recomienda la extracción a través de toracotomía o de VATS, ambos procedimientos permiten una adecuada exploración de las estructuras intra torácicas y reparar potenciales lesiones. En pacientes estables y casos seleccionados se pueden extraer sin cirugía (sin toracotomía o VATS); siempre en pabellón quirúrgico y bajo anestesia general, teniendo todo preparado para cirugía en caso de ser necesario.

Cierre espontáneo de fístula residual post cierre quirúrgico de fístula aorto-ventricular derecha traumática: Caso clínico / Spontaneous closure of a residual fistula after surgical closure of a traumatic aorto-right ventricular fístula: Report of one case

We report a 16-year-old boy, who suffered a right vent ride penetrating injury caused by a sharp blade that evolved to cardiac tampon. He underwent surgery and was discharged four days later. Thirteen days later, a cardiac murmur was found. An echocardiography showed an aorta-right ventricular fistula. Surgical closure was performed through an aortotomy on cardiopulmonary by pass. The control echocardiography showed a small residual fistula, which closed spontaneously three months later.
