Échographie cutanée haute résolution dans le diagnostic différentiel entre carcinome basocellulaire nodulaire et hyperplasie sébacée du visage : une étude pilote

HRUS is a non-invasive examination technique with excellent sensitivity for the detection of NBC in differential diagnosis with SH. Hypoechogenicity is not specific to NBC. The sensitivity of HRUS in our study suffered as a result of ultrasonography difficulties regarding unexpected differential diagnoses of NBC as well as tumour localisation in seborrhoeic areas.
