Abstract

|
|
Purpose : Eosinophilic granuloma is a rare benign tumor that is characterized histologically by the presence of destructive granulomas containing numerous Langerhans, cells. The most common presentation of eosinophilic granuloma is a painful, immobile scalp mass in the frontal and parietal bones occurring predominantly in children and adolescents or young adults. We report a representative case of eosinophilic granuloma.
Methods : A 16-year-old woman complained of an enlarging fixed scalp mass without pain and tenderness which measured at the frontal area, which had been found incidentally 2 months before. Plain skull x-ray showed a punched-out bone lesion. Computed tomography and magnetic resonance imaging showed a non-enhancing osteolytic lesion. The tumor and surrounding bony edges were completely removed via a bicoronal approach. The bony defect was reconstructed with bone cement.
Results : The tumor was involved frontal bone and dura mater. We confirmed the tumor by the documentation of Birbeck’s granules by electron microscopy. There is no evidence of local recurrence during postoperative 1.5 years.
Conclusion : The present case shows the characteristic feature of frontal bone involvment of the eosinophilic granuloma. The prognosis of eosinophilic granuloma depend on age at diagnosis and number of bones involved. We consider that best choice of treatment for eosinophilic granuloma is surgical excision.
