An irregular pulmonary nodule was confirmed diagnosis of aspiration pneumonia by finding plant cells through rapid on‐site evaluation

Abstract

ROSE for the specimen from the bronchoscopy could be done for the patient who has developed an unexplained pulmonary nodule and is helpful. If the non-human cells such as plant cells are found from the ROSE, aspiration pneumonia can be diagnosed immediately and the corresponding therapy may be performed, which may significantly shorten hospital stay, reduce hospital costs and improve patient outcomes.

“…That which we call a rose…”: A critical analysis of rapid on‐site evaluation

“…The earlier cytology and noncytology literature (ie, that published prior to 2015) includes discussions regarding the cost‐effectiveness of ROSE in fine‐needle aspiration (FNA) using mathematical models, the use of ROSE by endosonographers in diagnosing pancreatic solid lesions, the diagnostic accuracy of TBNA without ROSE, the role of the pulmonologist in ROSE, ROSE used essentially as a frozen section, comparison of ROSE by lesion size, and the comparison of liquid‐based and smear‐based cytology with and without ROSE . Although the majority of the literature is concerned with thoracic pathology, lesions of the thyroid, pancreas, breast, and head and neck as well as intra‐abdominal and submucosal lesions also are represented.…”
