How to diagnose Langerhans cell histiocytosis ?
How is Langerhans cell histiocytosis diagnosed? Testing for Langerhans cell histiocytosis (LCH) may include bronchoscopy with biopsy, x-ray, skin biopsy, bone marrow biopsy, complete blood count, and pulmonary function tests. Because LCH is sometimes associated with cancer, CT scans and a biopsy may be done to rule out possible cancer. Additional information about the diagnosis of LCH can be viewed on the Histiocytosis Association's website.
