Abstract:
A tissue floater or extraneous cross-contamination tissue on a microscopic slide is rare; however, it is a potential cause of diagnostic error. Occasionally, on collecting and processing of specimens, cross-contamination of tissue occurs leading to pathologic findings that are inconsistent with endoscopic findings. If the extraneous tissue is neoplastic, it can lead to a false-positive diagnosis. We present a case of discordant pathological and endoscopic diagnosis of invasive squamous carcinoma of the esophagus.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
