Juvenile xanthogranuloma of the nasal cavity.

Juvenile xanthogranuloma is a benign, normolipaemic, self-healing condition and a type of histiocytosis that occurs most frequently in infants and children. This condition usually presents with solitary or multiple cutaneous lesions and occasionally with visceral lesions. We report a case of juvenile xanthogranuloma occurring in the nasal cavity. We believe this is the first report, in the English literature, of juvenile xanthogranuloma occurring in this site.

Metastatic testicular teratoma of the nasal cavity: a rare cause of severe intractable epistaxis.

Malignant neoplasms of the nasal cavity and paranasal sinuses are uncommon. Choriocarcinoma is a highly malignant germ cell tumour occurring in the reproductive organs. Metastasis may be principally by the lymphatic route as in other germ cell tumours but choriocarcinoma is also known to spread haematogenously. We present a rare case of metastatic choriocarcinoma to the nasal cavity from testicular teratoma presenting with intractable epistaxis in a 32-year-old Caucasian male, who ultimately succumbed to this disease.
