[Show abstract][Hide abstract] ABSTRACT: A total of 106 patients with squamous cell carcinoma of the oral cavity and maxillary sinus in Nigerians were studied and analysed clinicopathologically for sex, age, site distribution as well as histological differentiation. The lesion was commoner in males than females (ratio 1.3 to 1.0) and was recorded in the age range 14 to 80 years. The mean age at presentation was 49 +/- 15.2 years, median age 49.5 years and a mode value at 51-60 years. The mandibular gingiva was the commonest anatomical site for the lesion, accounting for 28.6% of the total. Almost half of the cases (47.2%) presented histologically as well differentiated squamous cell carcinoma. Poorly differentiated squamous cell carcinoma was seen at a lower mean age 43 +/- 16 years when compared to other histological types.

[Show abstract][Hide abstract] ABSTRACT: An unusual case of odontogenic carcinoma with dentinoid is presented and discussed. This case is the first reported to show this peculiar histologic picture. The lesion recurred following what was deemed adequate surgical excision from both the clinical and histologic viewpoints. Adequate therapy and follow-up for such lesions is thus stressed.

[Show abstract][Hide abstract] ABSTRACT: A total of 2203 Nigerian school-age children (10-19 yr) were examined clinically for the presence of oral anomalies. The following prevalence figures were found: commissural lip pits (2.9%), ankyloglossia (0.2%), geographic tongue (0.3%), fissured tongue (0.8%), torus palatinus (4.5%), torus mandibularis (1.9%), snowcap type amelogenesis imperfecta (0.2%), localized enamel hypomaturation (11.7%), missing lateral incisors (0.7%), and peg lateral incisors (1.5%). None of the following conditions was found: cleft chin, cleft lip, double lip, medium rhomboid glossitis, bifid tongue, macroglossia, cleft palate or cleft lip and palate.

[Show abstract][Hide abstract] ABSTRACT: The first cases of focal epithelial hyperplasia from Nigeria and West Africa are presented. Although cases of this disease have been reported in Coloureds from South Africa, the three cases in this report represent the first in black Africans. The probability that the etiologic agent is a communicable agent, perhaps a virus, is reinforced by the clinical histories of the two related patients in this report.

[Show abstract][Hide abstract] ABSTRACT: The mean mesiodistal and buccolingual diameters are presented for the deciduous teeth from Pre-Columbian Peru. Generally, the deciduous teeth from Pre-Columbian Peru are larger in most dimensions than the deciduous teeth of modern populations of European descent and smaller than those of modern Australian aboriginals. Differences in crown dimensions between the Pre-Columbian Peruvian deciduous teeth and those from Prehistoric Inamgaon and Mesolithic Europe are inconsistent. However, the maxillary and mandibular second molars are larger in the Peruvian population while the incisors are smaller. Since comparative data for prehistoric deciduous teeth are rare, this paper adds valuable data to the growing literature on deciduous crown dimensions.

[Show abstract][Hide abstract] ABSTRACT: Two cases of recurrent ameloblastic fibroma are presented. One of the cases is very interesting from the standpoint of size, length of history, and histologic picture of the tumor. This patient presented with a tumor mass that had been present for 23 years and, after resection, weighed 2,072 grams. Despite a long history, the connective tissue that comprised the tumor lacked the maturation pattern reported in other cases of recurrent ameloblastic fibroma.

[Show abstract][Hide abstract] ABSTRACT: Two cases of adenomatoid odontogenic tumour affecting the jaws of two young Nigerian Africans are described. One was diagnosed clinically as a cyst, the other as an ossifying fibroma, but their true nature was later unmasked by histopathological studies. Although considered rare, the adenomatoid odontogenic tumour should be borne in mind in the differential diagnosis of radiolucent lesions of the jaws since an incorrect diagnosis may lead to mutilating surgery whereas the lesion is amenable to a conservative surgical approach. It is also important to examine histologically all excised specimens from the jaws even in the so-called 'obvious cases.

[Show abstract][Hide abstract] ABSTRACT: Tumors, tumor-like lesions and cysts of the oral cavity and jaw bones seen over a 5-year period, 1969-1974, in the Department of Oral Surgery and Pathology, Lagos University Teaching Hospital, Lagos, Nigeria, are reviewed using the World Health Organization's guidelines for histologic classifications. The histopathologic distribution of the 286 lesions seen over this period was as follows: tumors of non-odontogenic tissues, 180 cases (62.9%); tumors of odontogenic tissue, 37 cases (12.9%); cysts and periapical granulomas, 67 cases (23.4%) and tumors of debatable odontogenic origin, two cases (0.8%). On the strength of available evidence, this report does not share the view that jaw tumors are more common among Africans; instead, the report's conclusion agrees with the "harvesting" theory: that jaw tumors, which are generally slow-growing, painless and non life-threatening, are "showing up" more at treatment centres throughout Africa, thus giving a clinician the chance to see many cases of jaw lesions over a relatively short time.

[Show abstract][Hide abstract] ABSTRACT: The patients reported on here were seen and treated in the Department of Oral Surgery and Pathology, Division of Dentistry, Lagos University Teaching Hospital, between September, 1969, and September, 1974. Materials for histopathologic examination came from tissues removed at biopsy or surgical excision of the lesions. Out of a total of about 200 benign and malignant lesions of the oral cavity seen during the 5-year period (all cysts excluded), twenty-nine (15 per cent) were tumors arising from the odontogenic tissues as follows: ameloblastoma, nineteen; ameloblastic fibroma, two; adrenomatoid odontogenic tumor, two; ameloblastic fibro-odontoma, one; odontoma, two; cementoma, two; and calcifying odontogenic cyst, one. The author had the privilege of seeing all the patients and examining all the biopsy and surgical specimens.
