\n ⚕️ Nota clínica: Una puntuación LRINEC < 6 no excluye la fascitis necrotizante. El diagnóstico es fundamentalmente clínico y quirúrgico. Ante alta sospecha clínica, la exploración quirúrgica es el gold standard independientemente de la puntuación. Sensibilidad ~89%, especificidad ~97% para punto de corte ≥ 6.\n
