Cervical lymphadenopathies are widespread diseases in otorhinolaryngology. There are many differential diagnoses which have to be considered when swelling persists. To gain further information it is advisable to perform sonographically controlled fine needle aspiration biopsy (FNP). If there is no reliable result, it is necessary to remove a lymph node. We report on the rare case of isolated histiocytosis X in lymph nodes. A 63-year-old male had noticed a swelling of the right side of the neck about 6 weeks previously. The preliminary examinations (FNP/blood examinations) revealed no pathological findings. Only the histological examination delivered the diagnosis of histiocytosis X. Systemic manifestation was excluded by staging examinations. No further therapy was necessary after lymph node extirpation. The report demonstrates how to diagnose and treat this rare disease.

We report the case of a 55-year-old male patient who presented with non-specific pulmonary symptoms (cough, haemoptysis, fever up to 39 degrees C, night sweats and weight loss). After empirical antibiotic therapy prescribed by his primary care physician, the patient showed no improvement in symptoms. Laboratory findings were: elevated C-reactive protein and C-ANCA, leukocytosis and thrombocytosis, and anaemia. Chest radiography showed disseminated nodules bilaterally. On multidetector-row computed tomography (MDCT), the bronchial walls showed a significant thickening and extensive peribronchiolar consolidations. Bronchoscopy revealed diffuse erythema of the tracheobronchial mucosa with diffusely scattered white plaques. Histopathology described a multifocal ulcerative bronchitis with underlying chronic bronchitis. These findings in combination with the laboratory data lead to the diagnosis of Wegener's granulomatosis. Consequently, we started with an immunosuppressive therapy. Chest radiography after 10 days showed marked resolution of the infiltrates. Within 1 month, the patient became asymptomatic.

In case of complaints or clinical symptoms paediatricians should take the possibility of such neoplasias into consideration.
