RESUMO
Paget's disease of the bone is a chronic, progressive disease of unknown etiology, characterized by abnormal bony resorption and deposition. It is a common skeletal disease in Europe and North America, while it is very rare in Asia. Paget's disease of the temporal bone has been reported to cause hearing loss, tinnitus, and mild vestibular symptom. We report a 28-year-old man with Paget's disease, which was a first reported case of bilateral sensorineural hearing loss for the first time in Korea.

Juvenile xanthogranuloma (JXG) is a benign, normolipaemic, self-healing condition and a type of histiocytosis that occurs most frequently in infants and children, although adults may also be affected. This condition usually presents with a solitary or multiple cutaneous lesions and occasionally with extracutaneous lesions, especially the eye, lung, liver, kidney and pericardium. Histologically, JXG represents an accumulation of histiocytes lacking Birbeck granules (non-Langerhans cell), which can be differentiated from the Langerhans cells by specific staining techniques. The lesions may be excised for diagnostic, cosmetic or symptomatic reasons. We report a case of juvenile xanthogranuloma that occurred in the nasal cavity and testis for the first time.
