Abstract:
Background:Neuroblastoma (NB) frequently metastasizes to the bone marrow (BM), pleural and peritoneal cavities. The detection of NB cells in the BM and effusion specimens is important in clinical staging. Objective: The aim of this study was to compare the ability of flow cytometry (FCM) and cytomorphology (CM) in detecting NB cells. Materials and methods:From 21 patients with suspected NB metastasis, BM and effusion specimens were analyzed by FCM and CM. Results:A total of 16 effusion (76.2%) and 9 BM (42.9%) specimens were classified by FCM as positive for malignancy. CM revealed 12 (57.1%) and 9 (42.9%) positive effusion and BM specimens, respectively. There were three effusions detected by CM but not by FCM. There was no significant differences between FCM and CM in the detection of NB cells in effusions (p = 0.344). Conclusions:FCM can be used as an adjunct to CM for the detection of NB cells in effusion specimens.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
