Scalene node biopsy in diagnosis of intrathoracic diseases. Clinical notes

Scalene node biopsy (SNB) still represents a useful diagnostic method in the difficult interpretation of hilar-mediastinal adenopathies. Of 858 sample cases of intrathoracic pathologies of various etiology, SNB indicated a high histological degree of positivity in sarcoidosis in stages I and I + II (86%) and in malignant lymphomas (91%). As a result, the authors believe that when faced with a process of localization prevailing in the hilar-mediastinal lymphatic system, the SNB is a preferable treatment and should be performed before a mediastinoscopy.
