Numerous large irregularly shaped lytic lesions throughout the skull. There is an expansile lytic lesion involving the mid-right clavicle with irregularity and callous formation.
Case Discussion
Typical skull radiograph for Langerhans cell histiocytosis, showing irregularly-shaped lytic lesions with a beveled edge appearance. Increased thirst (due to diabetes insipidus) and skin rash also fit the diagnosis of Langerhans cell histiocytosis, which confirmed by skin biopsy.
