RESUMEN

This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients' histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil's Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.

RESUMEN

BACKGROUND: Hamartomatous polyp of the palatine tonsil is a rare benign tumor poorly recognized by clinicians and pathologists. We present a novel case report and provide a literature review about this diagnosis, highlighting its clinicopathological features and treatment modalities. METHODS: We herein report a case of a 22-year-old female patient who complained of a foreign body sensation in her throat. She presented with a pedunculated polyp attached to her right palatine tonsil, which was noticed 15 years ago. An excisional biopsy was performed under local anesthesia, and the microscopic aspect confirmed the diagnosis of the hamartomatous polyp of the palatine tonsil. The literature review was performed using the "palatine tonsil polyps" term in PubMed and Google Scholar. Only English-language publications showing clinical and microscopic descriptions were selected as inclusion criteria. RESULTS: As in our case report, this poorly understood lesion usually presents as a solitary, unilateral pedunculated mass attached to the palatine tonsil surface with nonspecific symptoms. The literature shows less than 100 cases reported, which reveals a lesion preference for male and young adult patients. Microscopically, it is characterized by disorganized proliferation of the connective tissue components indigenous to the involved site, with variable lymphangiectasia, which accounts for the diversity of the diagnostic term and its unknown incidence. Its treatment consists of excision of the polyp with or without tonsillectomy, and no recurrence or malignant transformation of these polyps has been reported. CONCLUSION: The hamartomatous polyp of the palatine tonsil is challenging due to its rarity and lack of standardization of the terminology used in the literature. Including this diagnosis in the 5th edition of the World Health Organization Classification for Head and Neck Tumors is expected to contribute to a better understanding of this pathology.

RESUMEN

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients' histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil's Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.
