“…2 The importance of microscopic diagnosis of tissues collected during oral surgical procedures cannot be underestimated, and the failure to submit biopsy samples for analysis could result in postponed or ignored diagnosis. 3 The hiring and consultation of oral and maxillofacial diagnostic histopathology specialists by general pathologists at hospitals or private laboratories are limited. Previous surveys and reports of oral pathology diagnostic services have suggested that experienced pathologists diagnosed oral and maxillofacial diseases by themselves despite they could not have the equivalent level of proficiency when examining oral samples.…”

Objectives:To investigate the awareness and usage of oral and maxillofacial pathology (OMFP) subspecialty services among pathologists in Saudi Arabia.Methods:In this cross-sectional study, we conducted an electronic questionnaire survey of pathologists in all regions of Saudi Arabia. The study was conducted between July 2015 and August 2016. The questionnaire comprised 19 questions to evaluate the knowledge of pathologists regarding microscopic OMFP and their perceptions towards this subspecialty.Results:Most of the pathologists surveyed (94.6%) were aware of the OMFP subspecialty and its scope of practice. Although most of the pathologists recognized the importance and need of this subspecialty, 70% of them never referred or consulted an oral pathologist as they either diagnosed the cases themselves or did not know any oral pathologist (57.7%). The pathologists had the greatest difficulty in identifying and diagnosing odontogenic tumors, salivary gland tumors, and odontogenic cysts.Conclusion:Pathologists are aware of the OMFP subspecialty, but their utilization of the services offered by OMFP specialists in Saudi Arabia is quite low despite the strong demand for OMFP services.

“…Furthermore, researchers have studied the profile usage of oral histopathology services. Previous studies have reported a predominance of specialists over general practitioners in the utilization of these services ( 3 , 12 ). This was attributed to the higher number of specialists at tertiary centers where oral pathology services are available.…”

“…This is due to the complex relationship of the various structures within the head and neck region, such as jaws, teeth and salivary gland amongst many others ( 2 ). However, certain principles guide the provision of a successful biopsy; most importantly the submission of a representative sample to the laboratory, as well as the preservation of excised tissue ( 3 ).…”

“…This is similar to what obtains worldwide where the practice of oral pathology is predominantly at tertiary/teaching institutions ( 4 ). Therefore, oral histopathology service provides a diagnostic laboratory for licensed practitioners and teaching materials for training both oral pathologists and dental students while serving as an archive of research material ( 3 ). However, oral pathology services may be scarce across Africa as previous reports have shown a shortage of pathology services in Sub-Saharan Africa ( 4 , 5 , 6 ), with dependence on general pathologists to do the oral histopathological diagnosis ( 7 ).…”

“…Slight variation has been observed in the prevalence of oral lesions from one geographic region to the other, probably due to variations in culture, habits, environmental pollutants and genetic composition ( 8 , 9 , 10 ). In a survey of oral and maxillofacial biopsies by Ali et al, malignant lesions accounted for 9.9% of lesions ( 11 ) while Oliveira e Silva et al, and Moridani et al, reported 6.32% and 2.38% respectively ( 3 , 10 ). On the contrary, an East African study reported a high prevalence of malignancies (67.28%), which was due to a selective inclusion of neoplastic lesions only ( 7 ).…”

BackgroundBiopsies are often essential for definitive diagnosis of oro-facial lesions and are a part of oral diagnostic procedures carried out in histopathology laboratories. At present, there is paucity of literature on the audit of oral histopathology services in Nigeria. The objectives of this study were to determine the prevalence of biopsied oral lesions in a Nigerian tertiary institution. Also to profile the usage of oral pathology service and to identify challenges that may be present in an oral histodiagnostic service.MethodsThis was a retrospective study performed at the Oral Pathology Department of the University of Ibadan/ University College Hospital, Ibadan, Nigeria. Reports of all biopsies submitted at the Oral Pathology laboratory, for the period 1990–2014, were reviewed and data extracted. Descriptive analysis was done using SPSS software, version 20.ResultsThe total number of reports was 1,998; invalid reports constituting 220(11%) were subsequently excluded leaving 1,778(89%) valid reports. The mean age of patients was 36.70±19.79, while the peak age of presentation was in the 3rd decade. Male to female ratio was 1:1.1, and the mandible was the most common site of lesions 619(34.8%). These services were mainly utilized by oral surgeons (83.9%) and ameloblastoma (11.5%) was the most frequently diagnosed lesion. CD45 (16.7%) was the most frequently requested immuno-diagnostic test.ConclusionBiopsied oral lesions were more prevalent in females, while oral and maxillofacial surgeons utilized these services the most. Inadequate biopsy specimens or unrepresentative specimens and deficient documentation were challenges identified in this study.

A proper antibody panel selection is one of the most important factors to reach an adequate diagnosis in challenging cases. This retrospective study was designed to determine the contribution of immunohistochemistry (IHC) in the primary diagnosis of oral diseases in one of the main services of oral pathology in the State of São Paulo, Brazil, and to identify the most common antibodies used, and recommend diagnostic algorithms based on our experience with challenging lesions. A total of 1698 IHC stains were performed in 401 cases from a total of 28,804 cases received from public dental clinics and private dental practitioners within a period of 13 years, representing a frequency of 1.4% of IHC solicitations. Among these, 112 (28%) were mandatory to reach a final diagnosis and 255 (63.6%) were confirmative. In 34 (8.4%) cases, it was not possible to reach a conclusive/final diagnosis, even with IHC. Regarding the nature of the lesions, 210 (52.3%) were benign, 163 (40.6%) were malignant tumors, 13 (3.2%) were reactive, 10 (2.5%) were premalignant, and 5 (1.2%) were lesions of uncertain malignancy. Small amount of tissue of some incisional biopsies, overlapping features of spindle cell lesions (epithelial, neural, melanocytic, smooth muscle, endothelial, and fibroblastic/myofibroblastic cell differentiation), and overlapping features of salivary gland lesions were the most frequent challenges in which IHC stains were requested. Spindle cell lesions were the most frequent (22%) among all cases that required IHC to reach a final diagnosis. The implementation of IHC for routine practice requires a wide range of markers, proper antibody selection, and knowledge to interpret the subjectivity of staining. The inherent limitation of incisional biopsies was pointed as a reason to inconclusive diagnosis, despite a wide range of antibodies that our laboratory displays.
