Langerhans cell histiocytosis.

Area of Science:

• Oncology
• Pathology
• Radiology

Background:

• Langerhans cell histiocytosis (LCH) is a complex neoplastic proliferation of Langerhans cells.
• It presents as three distinct clinical syndromes: eosinophilic granuloma, Hand-Schûller-Christian's disease, and Letterer-Siwe's disease, all with indistinguishable histology.
• These syndromes vary in severity and organ involvement, from localized bone or lung lesions to multi-systemic disease.

Purpose of the Study:

• To provide a comprehensive review of Langerhans cell histiocytosis (LCH).
• To discuss the historical context, histological features, potential causes, and therapeutic strategies for LCH.
• To highlight the critical role of radiographic findings and imaging techniques in diagnosing and managing LCH.

Main Methods:

• Literature review of Langerhans cell histiocytosis (LCH).
• Synthesis of information on LCH history, histology, etiology, and treatment.
• Focus on radiographic manifestations and imaging modalities for LCH diagnosis and management.

Main Results:

• LCH encompasses three syndromes with unified histology but diverse clinical presentations.
• Radiographic findings and specific imaging modalities are crucial for accurate LCH diagnosis.
• Understanding the spectrum of LCH is essential for effective patient management.

Conclusions:

• Langerhans cell histiocytosis (LCH) requires a multidisciplinary approach integrating clinical, histological, and radiological data.
• Effective management of LCH relies on accurate diagnosis through advanced imaging techniques.
• Further research into LCH etiology and treatment optimization remains important.
