Neural tumours of the head and neck
1Department of Oral and Maxillofacial Surgery and Oral Pathology/Oral Medicine, Faculty of Dental Sciences, University of Nairobi, P. O. Box 19676, Nairobi, Kenya.
Objective:
To document the pattern of occurrence of all primary neural tumours arising in the neck and craniofacial region over the period 1982 to 1991.
Design:
A retrospective study.
Setting:
Cancer Registry, Nairobi, Kenya.
Results:
Out of the 289 cases who were identified to have had whole body neural tumours, 225 (77.8%) had the lesions distributed in the neck and craniofacial area. While 80% of the neoplasms located in this region were retinoblastomas (mainly occurring in the age group 0 to 4 years), other lesion types occurred in small numbers thus: neurofibromas comprised 12.4%, Schwannomas four per cent, neuroblastomas and neuromas each 0.4%; and extracranial gliomas 2.7%. Overall, the male to female ratio was 1:1 and the site distribution revealed that over 90% of the lesions afflicted the upper face.
Conclusion:
Neural tumours of the neck and craniofacial region appear generally rare in this population as has been shown elsewhere.
