RARE TUMOURS OF THE DORSUM OF THE NOSE

*Lechosław P. Chmielik, Monsoor Sharifi

Summary
Introduction: Tumours of the dorsum of the nose are rarely found. The most common cysts of the dorsum are fibromas, chondromas and angiomas. Other tumours of the dorsum are even rarer. Any change within a child´s dorsum requires special attention.
It is important to eliminate the possibility of encephalomeningocele, as well as any connection with the anterior fossa of the skull.
Aim: To analyse case histories taken from children treated during 2005-2007 in the Paediatric ENT Clinic in Warsaw
Material and method: The case histories analysed are those of children treated in the last 3 years in the Paediatric ENT Clinic in Warsaw. The first case is that of an eight-month-old girl referred for a tumour in the dorsum of the nose. Histopathological examination after surgical treatment revealed a ganglioma. The second case concerns a nine-year-old boy with a cyst in the dorsum of the nose. During surgery, an atypical location of the cyst was found between the nasal bones and
the skin, terminating in the frontal bone.
Results: The first case is that of an eight-month-old girl referred for a tumour in the dorsum of the nose. MRI showed a tumour with no contact with the central nervous system. The child was qualified for surgery, which was carried out. The second case concerns a nine-year-old boy with a cyst in the dorsum of the nose. During surgery, an atypical location of the cyst was found, between the nasal bones and the skin, terminating in the frontal bone.
Conclusions: The most frequent causes of swellings in the dorsum of the nose are developmental defects. In unusually thin locations this is ganglioma, and a dermoid cyst can also have an atypical location.
