[Advanced stage laryngeal chondrosarcoma]. / Condrosarcoma laríngeo de alto grado de agresividad.

Chondrosarcoma is a tumor very seldom encountered in the larynx. In this location chondrosarcomas have typical features: slow growing, metastasis rares and scarce tendency to recur. But recurrences occurs at long-term and often can be controlled. We report a case diagnosed and treated in our Hospital which, on the contrary, recurrences presented in a short-term after first surgical removal. Clinical management and treatment of these neoplasms are reviewed.

Valoración anatomopatológica del ligamento cruzado posterior en 50 rodillas intervenidas de prótesis total / Anatomic and histological assessment of the posterior cruciate ligament in 50 knees treated with total arthroplasty

El papel y la función del ligamento cruzado posterior en una artroplastia total de rodilla continúan siendo motivos de controversia en cirugía protésica. Se planteó la valoración sistemática desde el punto de vista anatomopatológico de los ligamentos cruzados posteriores en un grupo de 50 rodillas sometidas a artroplastia total en las que se colocaron implantes con conservación del ligamento cruzado posterior, bajo el supuesto de que un ligamento cruzado posterior macroscópicamente intacto no tiene por qué estar histológicamente íntegro. Los resultados señalan que de los 50 ligamentos cruzados posteriores macroscópicamente íntegros en el momento de la cirugía, 47 casos (94 por ciento) presentaban una arquitectura histológica alterada con diferentes fenómenos degenerativos, lo cual hace cuestionarse cuál es el papel real de este ligamento cuando se conserva en las artroplastias de rodilla (AU)

[Clinical assessment and treatment of spontaneous perirenal hemorrhage]. / Evaluación clínica y tratamiento de la hemorragia perirrenal espontánea.

OBJECTIVES: Four cases of spontaneous perirenal hemorrhage are reviewed, with special reference to the clinical features, diagnosis and treatment. METHODS/RESULTS: Two were due to tumor (sarcomatoid carcinoma and angiomyolipoma) and the rest were secondary to renal lesions. All patients underwent nephrectomy due to hemodynamic instability. CONCLUSIONS: Nephrectomy appears to be the best treatment since this condition may arise from a malignant tumor which, to date, cannot be determined by any diagnostic method.

[Testicular cavernous angioma: a difficult clinical diagnosis]. / Angioma cavernoso de testículo: difícil diagnóstico clínico.

OBJECTIVE: The present report highlights the difficulty encountered in the diagnosis of cavernous testicular angioma in spite of the ultrasound study. METHODS/RESULTS: The clinical and ultrasound data of a patient with cavernous angioma of the testis were analyzed. To our knowledge, only 10 such cases have been reported in the literature. This condition could not be diagnosed on the basis of the clinical or ultrasound findings. CONCLUSIONS: Only pathological analysis and, therefore, surgical exploration can accurately diagnose cavernous angioma of the testis.
