Introduction: Pulmonary Langerhans cell histiocytosis (PLCH) is a rare interstitial lung disease characterized by the accumulation of Langerhans cells within the lung tissue. The diagnosis of PLCH traditionally involves clinical, radiological, and lung biopsy histopathological evaluations.
Case presentation: We present 2 cases where the diagnosis of PLCH was confirmed through the analysis of bronchoalveolar lavage (BAL) fluid cytology using immunoperoxidase technique, highlighting the significance of this minimally invasive technique in the diagnostic process. Clinical and radiological examination suggested advanced interstitial lung disease characterized by a fibrocystic pattern in both cases. The cytologic analysis of the BAL fluid revealed typical histiocytes with longitudinal grooves and eosinophils, which was better seen on liquid-based cytology (LBC) smears. ICC with CD1a, Langerin, and S-100 confirmed the diagnosis of PLCH.
Conclusion: Detecting PLCH through the examination of BAL cytology poses challenges, yet it is achievable, particularly with the assistance of LBC and ICC.
期刊介绍：
With articles offering an excellent balance between clinical cytology and cytopathology, ''Acta Cytologica'' fosters the understanding of the pathogenetic mechanisms behind cytomorphology and thus facilitates the translation of frontline research into clinical practice. As the official journal of the International Academy of Cytology and affiliated to over 50 national cytology societies around the world, ''Acta Cytologica'' evaluates new and existing diagnostic applications of scientific advances as well as their clinical correlations. Original papers, review articles, meta-analyses, novel insights from clinical practice, and letters to the editor cover topics from diagnostic cytopathology, gynecologic and non-gynecologic cytopathology to fine needle aspiration, molecular techniques and their diagnostic applications. As the perfect reference for practical use, ''Acta Cytologica'' addresses a multidisciplinary audience practicing clinical cytopathology, cell biology, oncology, interventional radiology, otorhinolaryngology, gastroenterology, urology, pulmonology and preventive medicine.
