Olfactory neuroblastoma. A report of 5 cases.
UNLABELLED: The present paper presents 5 cases of olfactory neuroblastoma (NO), showing the problems concerning the diagnosis and treatment. The olfactory neuroblastoma is a rare tumor that represents 1 to 5% of the malignant tumors of the nasal cavity. The wide range of the patient's age associated with variety clinical and histological findings, made the diagnosis often difficult. CONCLUSIONS: neuroblastoma has a difficult diagnosis; the histologic diagnosis should always be complemented by the immunohistochemical investigation; surgical resection with adequate margins is the first treatment on resectable lesions.
["Osteogenesis imperfecta": some differential particularities with otospongiosis].
The authors present 3 cases of osteogenesis imperfecta, with auditory repercussions similar to otospongiosis. A review of the literature of the pathology highlights its relationship with the temporal bone. The findings and treatment of 3 cases are discussed. The author conclude that this pathology may suggest otospongiosis with a progressive neuro-sensorial loss of hearing. The treatment of choice is the use of a hearing aid, rather than surgery.
