Neurosurgical management of a painful subcutaneous nodule of the knee: angioleiomyoma

Lateral Femoral Cutaneous Nerve Angiomyoma

Angiomyomas are benign tumors derived from smooth muscle cells of vessels. They are principally a pathology of the peripheral nervous system where they involve cutaneous nerves, causing pain and paresthesia. We present a case of a lateral femoral cutaneous nerve angiomyoma and its surgical treatment. A 24-year-old female presented to clinic with right thigh pain in the distribution of the lateral femoral cutaneous nerve, which had been ongoing and progressive for seven months. There was associated numbness and tingling. A lesion was noted in the anterior subcutaneous tissues of the thigh on contrasted CT and MRI. The patient was taken to the operating room where a pearly white lesion was found within the subcutaneous tissue. No effect was seen with stimulation of the lesion. The lesion was removed en bloc, and pathological analysis revealed an angiomyoma. Post-operatively, the patient reported complete resolution of all symptoms, namely, pain and paresthesia. No similar reports were identified within the literature. Together, angiomyomas have been described within the lower extremities to cause pain and paresthesia. This is the first reported case of an angiomyoma involvement within the lateral femoral cutaneous nerve. Complete surgical resection, in this case, was curative and diagnostic.

Meta-ranking de universidades. Posicionamiento de las universidades españolas

Este estudio propone la elaboración de un meta-ranking con las 14 universidades españolas que aparecen en al menos cuatro de los cinco rankings globales considerados, que son de reconocida notoriedad internacional. Se puede diferenciar entre rankings de investigación con datos bibliométricos y rankings que tienen en cuenta otros aspectos y otras formas de recabar datos basadas en encuestas. Las universidades españolas alcanzan mejores posiciones en los primeros que en los segundos. Se pone de relieve una debilidad mayor en la internacionalización, la reputación o el ratio estudiante-profesor que en los indicadores de investigación. Son excepción las universidades que destacan en las dos dimensiones. A la vista de estas conclusiones resulta evidente la necesidad de profundizar en una mayor internacionalización, en mejorar la reputación y mejorar la visibilidad internacional de la universidad española.
