Con la adición de técnicas complementarias como la toma de biopsia con sonda criogénica, se amplía aún más el papel de la evaluación de la patología pulmonar y mediastínica, lo que permite un mejor rendimiento diagnóstico.  Presentación del caso:  paciente masculino de 63 años, sin antecedentes de familiares directos con cáncer, índice tabáquico de 50 paquetes/año, suspendido tres meses previos a su valoración por disfagia, sin mejoría por lo que acude a valoración médica. Se le efectúa tomografía de tórax simple y contrastada; presenta lesión mediastinal subcarinal de 58 × 51 × 74 mm y masa en segmento apical de lóbulo superior derecho, por lo que se decide realizar broncoscopia para toma de biopsia transcarinal. Las cuales se practicaron mediante traqueoscopia rígida y broncoscopia flexible, realizando aspiración con aguja Wang, posteriormente se introdujeron pinzas fórceps y, finalmente, criosonda flexible a través del mismo sitio de punción; no hubo datos de hemorragia posterior a los procedimientos. Se obtuvo tejido de tamaño de 0.6 × 0.3 × 0.2 cm mediante criobiopsia, ideales para realizar estudios de inmunohistoquímica y mutaciones en patología.]]></p></abstract>

With the addition of complementary techniques, such as taking a biopsy with a cryogenic probe, the role of the evaluation of pulmonary and mediastinal pathology is further expanded, allowing better diagnostic performance.  Case description:  63-year-old male patient, with no history of direct family members with cancer, smoking rate of 50 packs/year, suspended three months prior to his evaluation due to dysphagia, without improvement, so he went to medical evaluation. A simple and contrast-enhanced chest tomography was performed, presenting a subcarinal mediastinal lesion measuring 58 × 51 × 74 mm and a mass in the apical segment of the right upper lobe, so it was decided to perform bronchoscopy to take a transcarinal biopsy. Which were performed using rigid tracheoscopy and flexible bronchoscopy, performing aspiration with a Wang needle, subsequently Forceps clamps and finally a flexible cryoprobe were introduced through the same puncture site with no evidence of hemorrhage after the procedures. Tissue measuring 0.6 × 0.3 × 0.2 cm was obtained through cryobiopsy, ideal for carrying out immunohistochemistry and mutation studies in pathology.]]></p></abstract>
