Abstract:
Idiopathic pleuroparenchymal fibroelastosis is a rare idiopathic interstitial pneumonia. It was first described in 2004 and subsequently included in the ATS/ERS classification of idiopathic interstitial pneumonia in 2013. There have been few cases reported so far. The diagnostic criteria is still emerging and its etiology is being questioned. We report a case of pleuroparenchymal fibroelastosis probably idiopathic, the first of its kind to be reported from India, and a brief review of the literature.
Insights
Idiopathic pleuroparenchymal fibroelastosis, a rare lung disease, is increasingly recognized. This report details the first case from India, contributing to understanding this interstitial pneumonia.
Area of Science:
- Pulmonology
- Respiratory Medicine
- Interstitial Lung Diseases
Background:
- Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a rare idiopathic interstitial pneumonia.
- First described in 2004, IPPFE was incorporated into the ATS/ERS classification in 2013.
- Limited case reports highlight the emerging diagnostic criteria and debated etiology of IPPFE.
Observation:
- This study presents a case of pleuroparenchymal fibroelastosis in India.
- The case is likely idiopathic, representing the first reported instance from the region.
- The report includes a concise review of existing literature on IPPFE.
Findings:
- The case contributes to the scarce global data on idiopathic pleuroparenchymal fibroelastosis.
- This report underscores the need for further research into the diagnosis and causes of IPPFE.
- The presentation highlights the geographical diversity of IPPFE cases.
Implications:
- This case report expands the geographical understanding of idiopathic pleuroparenchymal fibroelastosis.
- It emphasizes the importance of recognizing IPPFE in diverse clinical settings.
- Further research is crucial for refining diagnostic criteria and elucidating the etiology of IPPFE.

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.
