Data on the prevalence of these tumours is scarce from the Afri-can continent. We present a 19-year audit of benign jaw tumours and tumour-like lesions at a University teaching hospital in Nairobi, Kenya. Methods: Histo-pathological records were retrieved and re-examined from the Department of Oral and Maxillofacial pathology, University of Nairobi from 1992 to 2011. The jaw tumours were classified according to the latest WHO classification. Results: During the 19-year audit, 4257 biopsies were processed of which 597 (14.02%) were jaw tumours within an age range of between 4 to 86 years. There was greater number of odontogenic tumours 417 (69.85%) than the bone related lesions 180 (30.15%). Of the odontogenic tumours, the epithetlial and in the bone related types, the fibro-osseous lesions were frequent. Conclusion: Ameloblastoma and ossifying fibroma were the most frequent tumours reported in this audit. The information regarding the prevalence of these tumours is scarce from the continent and can be useful in early detection and management before they cause facial deformity.展开更多

Very rarely we will find benign salivary gland tumor in nasal cavity. Pleomorphic adenoma is still the most common pathological variety either in major or minor salivary gland tumors. In the nasal cavity, even though most of the accessory salivary glands are present in the lateral wall of nose, nasal septum remains the most common site of origin. <strong>Case Report:</strong> A 40-year-old female presented with right-sided nasal obstruction and epistaxis. CT scan of Nose and Paranasal sinuses found a lesion involving the anterior third of the right nasal cavity. The patient underwent complete surgical resection of the tumor via an endonasal approach. Histological examination found a mixed cellular component (epithelial and myoepithelial) and mesenchymatous tissue with chondromyxoid stroma, enabling diagnosis of a typical pleomorphic adenoma. <strong>Conclusion:</strong> Pleomorphic adenoma is the most common salivary gland tumor but rare to find in the nasal cavity with only few cases reported in the literature. Although benign, the risk of local recurrence, malignant transformation and metastasis requires close long-term follow-up.展开更多

Imaging revealed a tumour eroding through the inner and outer skull tables, closely associated with major underlying dural sinuses. She underwent complete macroscopic resection of the tumour and reconstruction of a titanium mesh cranioplasty. Histology favoured a benign process with a diagnosis of BFH of the calvarium given. At 1 year follow-up, the patient is asymptomatic and has not developed recurrence of the tumour.展开更多

Aim: To describe the dermographic and histopathological patterns of salivary gland tumuors in a tertiary health institution Sokoto. Materials and Method: This was a five-year descriptive and retrospective analysis of all patients diagnosed and managed with salivary gland tumour in the department of ear, nose and throat, Usmanu Danfodiyo University Teaching Hospital Sokoto between January 2010 and December 2014. Clinical records and histopathological slides of these patients were retrieved and data extracted from the case files included patients demography, site of the tumour, and histopathological diagnosis. Data obtained were analysed using IBM-SPSS version 22. Results: A total of 103 salivary gland tumours (SGTs) during the study period. Age ranged from 1 year to 75 years with a mean age of 41.66 (±17.80) years. There was a male preponderance of 53.4% and 46.6% female with a M:F of 1.2:1. Histologically, 35 (34.0%) were benign and 68 (66.0%) were malignant lesion. Minor salivary gland 63 (61.2%) was the commonest gland involved followed by the parotid 27 (26.2%) gland. Squamous cell carcinoma (SCC) was most frequent malignant lesion and pleomorphic adenoma was the commonest benign tumour. Conclusion: Minor salivary glands of the palate are the principal site for salivary gland malignancy with male preponderance and SCC being the most frequent malignant lesion. Therefore any SGTs should raise a high index of suspicion.展开更多
