Predictors of mediastinal staging and usefulness of pet in patients with stage IIIA (N2) or IIIB (N3) lung cancer.

Objective: To analyze which factors predict mediastinal N2/N3 lymph node staging and diagnostic accuracy of PET and CT to determine it.

Patients And Methods: We analyzed data collected prospectively in a database that included patients with non-small cell lung cancer (NSCLC) who underwent EBUS-TBNA. Prior to EBUS-TBNA, CT and PET were used to define the radiographic N stage and lymph nodes with short axis ≥ 1 cm by CT or with ratio between maximum standardized uptake value (maxSUV), by PET, of lymph node and primary tumor greater than 0.

[Chronic pulmonary histoplasmosis diagnosed in a nonimmunosuppressed patient 10 years after returning from an endemic area].

We report the case of a Spanish nonimmunosuppressed patient who was a chronic alcoholic and who developed chronic cavitary pulmonary histoplasmosis. He had been living in Venezuela until 10 years ago. The diagnosis was established when Histoplasma capsulatum was cultured from bronchoscopy samples.
