Resumen

Se presenta el caso clínico de un varón de 44años de edad, sin antecedentes de interés, intervenido quirúrgicamente en nuestro servicio de una lesión ocupante de espacio supraclavicular diagnosticada tras un cuadro de un mes de evolución de paresia distal progresiva del miembro superior izquierdo. Tras el análisis histológico de la lesión resecada el diagnóstico fue de necrosis grasa encapsulada. Dicha entidad se caracteriza a nivel histológico por presentar una estructura quística, encapsulada, con necrosis grasa en su interior e infiltrado inflamatorio en su pared. La compresión de estructuras nerviosas secundaria a esta lesión tumoral es excepcional, la cual suele localizarse en miembros inferiores, especialmente en zonas expuestas a traumatismos. En el presente trabajo se expone el primer caso descrito de compresión supraclavicular del plexo braquial a consecuencia de una necrosis grasa.

Palabras clave:

Abstract

We report the case of a 44-year-old male, lacking clinical history of previous illness, who had surgery at our hospital to treat a mass in the supraclavicular space. The patient presented with a 1-month progressive distal paresis of the left arm. The histo-pathological examination of the mass revealed an encapsulated fat necrosis. Fat necrosis is characterised by cystic architecture, encapsulation with fat necrosis within, and inflammatory infiltration of its walls. Neural structure compression secondary to this tumour mass is very rare. Fat necrosis is more frequent in the lower limbs, in areas exposed to trauma. This article is the first report of brachial plexus compression due to supraclavicular fat necrosis.

Keywords:
