Answer

The classic multifocal form of LCH (Hand-Schüller-Christian disease) includes diabetes insipidus, exophthalmos, and bony defects, particularly of the cranium. Lesions may affect a variety of systems, including liver (20%), spleen (30%), and lymph nodes (50%). Pulmonary involvement may occur. Osteolytic lesions of the long bones can lead to spontaneous fractures.

One third of patients have mucocutaneous lesions, most frequently infiltrated nodules and ulcerated plaques, especially in the mouth, axillae, and anogenital region. Other cutaneous manifestations include extensive coalescing, scaling, or crusted papules.
