ABSTRACT

Since its establishment in 1990, a total of 22 patients with confirmed Langerhans cell histiocytosis (LCH) have been monitored and treated at the Clinic of Internal Medicine Haemato-Oncology in Brno. In 5 patients, the disease was diagnosed in childhood and 2 of these 5 patients had late neurodegenerative changes in the CNS with a typical picture on MR and a typical PET-CT imaging fluorodeoxyglucose hypometabolism in the cerebellar area. In 5 patients from the cohort of 22, the disease had unifocal form, dominant in the area of skeleton with no recurrence after the treatment. However, in 12 patients, the disease affected a number of organs simultaneously (multifocal form of LCH). The aim of the description below is to characterise the monitored cohort of 22 patients and describe the very different courses of multifocal forms of LCH in 12 patients.
