Background: Histological diagnosis is invaluable in charting the overall management of human pathologies. Knowledge of the general trend of histological diagnosis in a population may impact the clinician's practice as well as public health policy formulation. There is a paucity of literature on biopsy-driven epidemiology of oral and maxillofacial lesions, especially in sub-Saharan Africa.
Objective: This study aims to determine the pattern of biopsied oral and maxillofacial lesions at a Nigerian tertiary hospital.
Materials and Methods: A 5-year retrospective review of the histological diagnoses of patients who had biopsies of oral and/or maxillofacial lesions done at our teaching hospital was done. Biopsy reports obtained within the study period were retrieved and analyzed. Analysis was performed using the IBM SPSS statistics for windows version 20 (IBM Corp, Armonk, NY) software.
Results: Three hundred and sixteen biopsy reports were included in this review. A slight male preponderance was observed, with a male-to-female ratio of 1:0.96. The age ranged from 6 months to 90 years (mean ± standard deviation, 33.3 ± 19.9). The posterior mandible was the most commonly affected site 13.9% (44). Most of the lesions were neoplastic 70.9% (224) with a slight majority being malignant. Squamous cell carcinoma (SCC) was the most frequently diagnosed malignancy 11.7% (37). Most nonneoplastic lesions were inflammatory/infectious 52.8% (47).
Conclusion: Nearly equal gender prevalence for oral and maxillofacial biopsies was observed. In contrast to several studies, malignancies were more frequently diagnosed than benign neoplasms. The high incidence of SCC suggests the need for population interventions targeted at screening and early diagnosis.

  Introduction Top

Histological diagnosis is invaluable in deciding the choice of treatment and overall management of human pathologies.[1],[2],[3] This has tremendous impact on the prognostication of such diseases, morbidity and mortality.[3],[4] Having the knowledge of the general trend of histological diagnosis in a population might influence not only on the clinician's practice but also the health planning and policy formulation. Moreover, reviews of histological diagnoses may give an insight into the epidemiology of diseases in an environment which may also serve as a basis for the developing and driving health policies.

There is a paucity of literature on hospital-based biopsy-driven epidemiology of oral and maxillofacial lesions worldwide; this is especially so in sub-Saharan Africa. This study aims to provide information on the pattern of histological diagnoses of oral and maxillofacial lesions made at a Nigerian tertiary hospital.

  Materials and Methods Top

A retrospective review of the histological records of patients who had tissue biopsy done at our department between January 2013 and December 2017 was done. For biopsies that were repeated, only the most representative result was recorded for the patient. Fine-needle aspiration biopsies results, nonspecific results, and histopathological reports with no identified pathologies were excluded. Furthermore, cases with ambiguous or indecisive histopathology reports were excluded. The patients' gender, age, site of the tumor, and classification of the lesion were extracted from our records.

A modification of the classification used by Pinto and de Araújo[5] was utilized to classify the site affected into anterior mandible, posterior mandible, anterior maxilla, posterior maxilla, anterior and posterior mandible, anterior and posterior maxilla, upper lip, lower lip and its mucosa, upper lip and its mucosa, tongue, and floor of the mouth, cheek/buccal mucosa.[5] Where the location was not stated, they were grouped as “not specified.” The anterior maxilla and mandible refer to the segment of the maxilla or mandible between the distal aspect of the right canine and the distal portion of the left canine. The posterior maxilla and mandible refers to the segment of the maxilla or mandible between the mesial aspect of the first premolar and the distal aspect of the third molar.

The lesions were broadly classified as neoplastic and nonneoplastic. The neoplastic lesions were further divided into benign and malignant. The nonneoplastic group was additionally divided into six subgroups using a modification of the classification system employed by Guedes et al.[6] These are cystic lesions, adaptive/reactive lesions, inflammatory/infectious lesions, autoimmune/metabolic lesions, vascular lesions, and hamartomatous/congenital/developmental lesions.

  Results Top

A total of 316 biopsy results were included in this 5-year review. A slight male preponderance was observed, with a male-to-female ratio of 1:0.96 [Table 1]. The age ranged from 6 months to 90 years (mean ± standard deviation, 33.3 ± 19.9) [Table 1]. The modal age group of presentation was the third decade of life (21–30 years) [Figure 1]. Most of the biopsies were obtained intraorally 231 (73.1%). The anatomical site most frequently affected was the posterior mandible 13.9% (44) [Figure 2]. Majority of the biopsies were neoplastic 70.9% (224), while 29.1% (92) were nonneoplastic. Of the neoplastic lesions diagnosed, a slight majority were malignant lesions [Table 1]. A ratio of 1.1:1 was observed between the malignant and benign neoplastic lesions correspondingly. The most commonly encountered benign neoplasm was ameloblastoma 11.1% (35), while squamous cell carcinoma (SCC) was the most frequently diagnosed malignancy 11.7% (37) [Table 2].

Salivary gland lesions constituted 18.7% (59) of all the diagnosed biopsies [Table 2]. Most of the salivary gland tumors were malignant accounting for 64.4% (38) of all salivary gland neoplasms. Pleomorphic adenoma was the most common benign salivary gland neoplasm representing 7.9% (25) of all biopsies, while mucoepidermoid carcinoma was the most frequently diagnosed malignant salivary gland tumor accounting for 4.1% (13) of all biopsies [Table 2].

Among the nonneoplastic biopsies obtained, most were inflammatory or infectious in nature 52.8% (47), followed by the reactive lesions 13.5% (12).

  Discussion Top

Reviews of histological diagnoses at hospitals provide an important insight into the epidemiology of diseases. Such information may be deployed in the formulation and/or implementation of health policies.

Male preponderance was noted in this study which is similar to the reports by Bello et al.[7] and Ha et al.[8]. However, it contrasts with the report by Lima et al.[9] who reported a female preponderance and that of Sohal and Moshy[10] who reported equal sex prevalence. The observed male dominance in this study may not be a true reflection of the incidence of oral and maxillofacial lesions between the male and female genders. Our society is still largely patriarchal, and thus, males are more likely to be empowered enough to seek quality health care.[11] Moreover, out-of-pocket payment for health care is widespread in our climes, and males being generally more financially empowered are more likely to be able to access health care.[12],[13]

The age range observed in this study was similar to those of several studies reported in the literature.[7],[14],[15]

The posterior mandibular region was the most frequently involved anatomical site in this series. This is similar to the results of other studies in the literature.[16],[17],[18] These observations may be attributed to the penchant of both primary and metastatic neoplasms for the mandible.[16],[19] Furthermore, some lesions have been associated with tooth impaction, which occurs most commonly in the posterior mandible.[20],[21] The posterior mandible is also replete with active hematopoietic sites and rich capillary vessels, which may entrap metastatic tumors cells and initiation of primary tumors.[19] Moreover, odontogenic infections and chronic inflammation are prevalent in the posterior mandible.[22],[23] Promotional influence of chronic inflammation on cellular mutation, proliferation, and tumorgenesis has been previously documented in the literature.[19],[24] Interestingly, Pinto and de Araújo,[5] in a study conducted among a Brazilian population, reported the lip to be the most common site for biopsies. This disparity may be associated with the higher prevalence of lip lesions among Caucasians.

Neoplastic lesions accounted for the majority of the diagnosed lesions in this study. We opine that the seemingly low incidence of nonneoplastic lesions in this study may be related to the typical persistent growth of neoplastic lesions.[13],[25] This may result in significant morbidity and impairment of patients' quality of life, therefore compelling them to present at the hospitals.[13],[25],[26] This is especially so in our environment where patients are often hindered from presenting early due to a myriad of factors.[27],[28],[29] Pain, swelling, consequent impairment of function, and reduced quality of life are some of the major factors that eventually compel patients to present at hospitals in our climes.[30],[31]

Malignancies featured prominently among the neoplasms, constituting a slim majority. This observation agrees with some reports in the literature.[32] However, it is in disagreement with multiple studies in the literature, where higher frequencies of benign lesions were reported.[14],[15],[33],[34] This contrast may be because some of the studies were limited to pediatric populations, where benign lesions are more regularly encountered than malignancies.[10] It may also be an indication of the risk of developing malignancies compared to benign neoplasms among the study population.

Ameloblastoma was the most commonly diagnosed benign neoplasm. This is in agreement with several African studies, although, it is at dissonance with some European or American study.[15],[35],[36] Some authors have hypothesized that ameloblastoma has a predilection for persons of African descent.[37],[38] Odontomas are reported to be the most frequently diagnosed odontogenic tumors among younger age groups in several European articles.[39],[40],[41] This may be because they are generally asymptomatic and are often diagnosed during routine visits to the hospital. Routine visits to the hospital for evaluation are not a widespread practice in our climes; therefore, the frequency of these lesions may not be properly appreciated.

SCC was the most frequently diagnosed malignant neoplasm in this study. This agrees with the reports of several studies, both within and outside Africa.[26],[42],[43] This may be related to the increasing prevalence of indulgence in deleterious practices such as tobacco smoking, snuff dipping, and unsafe sex practices in our environment.[26],[44] Extraorally located SCC was not frequently encountered in this study. The reason for the relative rarity of extraorally sited SCC may be attributed to the fact that this study was done among mostly dark-skinned individuals. Melanin has been proven to confer some protection against the unwanted effects of ultraviolet rays.[45],[46]

Salivary gland lesions constituted a large proportion of the total sample size. This is in higher than figures reported by Akinyamoju et al.[47] who reported that salivary gland lesions and neoplasms constituted 11.02% (196) of oral histopathology reports in their study. This observation may be because they included histopathology reports of normal tissue in their data analysis. Ha et al.[8] and Ali et al.[14] reported even lower incidence of salivary gland lesions in their study although the former study was based on a pediatric population and the latter included a significant number of the neck, laryngeal, and thyroid gland lesions.

Majority of the salivary gland neoplasms were found to be malignant in the present study. This agrees with some reports in the literature.[48],[49],[50] In contrast, Jaafari-Ashkavandi and Ashraf[51] stated that the benign salivary gland lesions are more common.[51] In consonance with most reports in the literature, pleomorphic adenoma was the most commonly diagnosed benign salivary gland neoplasm in this study.[52],[53] Mucoepidermoid carcinoma featured as the most frequently diagnosed salivary gland malignancy in this study. Differing reports exist in the literature about the identity of the most common malignant salivary gland neoplasm. While some studies have stated that mucoepidermoid carcinoma is the most common, others have presented adenoid cystic carcinoma as the most common.[26],[50]

Inflammatory/infectious lesions represented the most common category of diagnosed nonneoplastic lesions. This is not unexpected because chronic odontogenic infections are commonly encountered in our environment.[54],[55] In our climes, it is common for infective or inflammatory lesions arising from neglected carious lesions to progress into more sinister clinical entities.[54],[56] Cystic lesions were relatively less frequently diagnosed in this study compared to other studies in the literature.

  Conclusion Top

Almost equal gender prevalence for oral and maxillofacial biopsies was observed in this study. The third decade of life was the modal decade of presentation. In contrast to several studies, malignancies were more frequently diagnosed than benign neoplasms, indicating that oral and maxillofacial surgeons should have a high index of suspicion while managing the patients. However, further studies are needed to explore this. Furthermore, studies to determine factors that may be responsible for this untoward observation should be implemented. The high incidence of SCC suggests that population interventions targeted at screening and early diagnosis should be explored.
