LCH of Bone : Introduction
Langerhans Cell Histiocytosis (LCH) of Bone: Bone lesions are the most common clinical presentation in LCH. Bone involvement may be unifocal (eosinophilic granuloma) or multifocal. The lytic bone lesions arise within the medullary cavity, erode the cortex and involve adjacent soft tissue. They may be asymptomatic initially but usually cause pain, tenderness, or pathologic fractures.
