Background:
The localized form of the Langerhans cell histiocytosis was referred to earlier as eosinophilic granuloma, which has the best prognosis of all histiocytosis syndromes concerning survival. The non-malignant proliferative disorder of the histiocytic system is still of unknown etiology. Characteristic radiographic signs are osteolytic lesions.
Patient:
We report on an otologic manifestation of a 20-year-old man's temporal bone, which developed three years after a successful treatment of an eosinophilic granuloma of the mandible.
Results:
Surgery and low-dose irradiation led to a complete remission of the disease. Other manifestations of the disease were not detected until now.
Conclusions:
In the presence of chronic aural discharge, Langerhans cell histiocytosis must bei considered in differential diagnosis and a histopathological examination should be performed.
