Abstract:
356 patients were studied suffering from lymph node swelling of the neck, supraclavicular region, axilla and groin. A primary or secondary malignant process was confirmed in 196 cases, reactive or granulomatous changes were found in 151 cases, in 64 smears there were only a few lymphocytes and connective tissue.

Sputum Studies I: Gram Stain, cytology, and Acid-fast smear and culture
Sputum studies are a critical part of diagnosing and treating numerous respiratory conditions. These studies involve obtaining sputum samples for analysis to identify pathogenic organisms and assess the presence of abnormal cells indicative of malignant conditions. This lesson will delve into three fundamental sputum studies: Gram Stain, Cytology, and Acid-fast Smear and Culture.

Endoscopic Studies II: Thoracocentesis
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
