Pleomorphic Adenoma of the Salivary Glands: Two Atypical Locations

Pleomorphic adenoma is the most common tumor of the salivary glands, accounting for approximately 50% of salivary gland lesions. It develops mainly in the salivary glands: parotid (80%), submaxillary (10%), sublingual (1%) and in the accessory oral-pharyngeal glands (9%). The aim of this work was to report 2 cases of pleomorphic adenoma of atypical location and then to discuss the difficulties linked to its diagnostic and therapeutic management in the Malian context. They were a 40-year-old man and a 72-year-old woman. They were admitted to the ENT department of the “Luxembourg Mere-infant” hospital for oropharyngeal swelling for the first and swelling of the palate for the second. The clinical expression was a swelling in both cases, of a hard, mobile consistency with healthy mucosa on their surface. The remainder of the physical examination was unremarkable. The diagnosis of a tumor of the oropharynx and palate was made following clinical radiological examinations. The histopathological examination of the surgical specimen made it possible to make the diagnosis of pleomorphic adenoma of the palate and the left palatine tonsil. The follow-up surgery was straightforward, with a favorable outcome. Pleomorphic adenomas are relatively rare benign tumors of the accessory salivary glands;their clinical expression remains swelling. Therapeutic management is surgery and the diagnosis is confirmed by histopathological examination.

Clinical and Histopathological Review of 229 Cases of Ranula

引用

Journal of Huazhong University of Science and Technology(Medical sciences) 2011年第5期31卷 717-720页

作者：贾玉林赵怡芳陈新明 department of oral and maxillofacial surgery Union Hospital Tongji Medical College Huazhong University of Science and Technology department of oral and maxillofacial surgery College and Hospital of Stomatology Wuhan University department of oral Pathology Wuhan University

The purpose of this paper was to evaluate the relationship between the thrombosis and secretory duct dilation, lesion size, clinical types, nature （primary or recurrent） and duration of illness in the development of ranula. A total of 229 cases of sublingual gland cysts were treated with surgical resection from Jan. 1990 to Feb. 2010. The patients＇ data were investigated on histopathological findings, size of ranula, the clinical types, nature of ranula （primary or recurrent） and duration of illness. Sections from the paraffinembeded blocks were HE-stained. CK expression was immunohis-tochemically detected. Among 229 cases the incidence of venous thrombosis was 58.52%. The incidence of venous thrombosis with or without duct dilation was 73.25% and 26.39% respectively, with a significant difference between the two groups （P〈0.005）. The incidence of venous thrombosis of ranulas with diameter larger or less than 3 cm was 72.22% and 46.28% （P〈0.005）. The incidence of venous thrombosis of oral ranula, plunging ranula and mixed ranula was 49.37%, 77.19% and 85.71% respectively, with a significant difference found between oral and plunging or mixed ranula （P〈0.01）. The incidence of venous thrombosis in ranula patients with duration of illness longer or less than 3 months was 69.77% and 51.75% （P〈0.01）. The incidence of venous thrombosis with recurrent and primary ranulas was 51.85% and 64.85%, without a significant difference noted between them （P〉0.05）. It is concluded that the formation of venous thrombosis was related to the dilation of secretory duct, lesion size, clinical types, duration of lesion but formation of venous thrombosis was not related to the nature （primary or recurrent） of ranulas.

Open Journal of Epidemiology 2024年第2期14卷 297-311页

作者： Jocelyne Valerie Gare Filwende Dan Kientega Ouedraogo Carole Nathaie Tenin Ouattara Seydou Kabore Wendpoulomde Aime Désire Nicolas Meda Training and Research Unit in Health sciences Department of Public Health Joseph Ki Zerbo University Ouagadougou Burkina Faso Training and Research Unit in Health sciences Department of Dental Surgery Joseph Ki Zerbo University Ouagadougou Burkina Faso

Introduction: Several studies have reported a high prevalence of dental caries among the people with intellectual disabilities. In order to identify the sociodemographic, clinical and behavioral factors associated with it, we conducted a study in specialized centers welcoming subjects with intellectual disabilities in Ouagadougou (Burkina Faso). Objectives: The objective of this study was to identify the factors associated with it among intellectually disabled in the specialized centers of Ouagadougou. Methods: The study was cross-sectional analytical. The survey took place between November 2020 and January 2021 among people with intellectual disabilities in reception centers receiving a grant from the Ministry of Women, National Solidarity, Family and Humanitarian Action. Data collection was done with a questionnaire adapted from the World Health Organization (WHO) and dental caries was recorded according to WHO criteria in decayed, missing or filled teeth generating a DMF index. Logistic regression was used to identify factors associated with the presence of dental caries. Results: A total of 193 participants were included in the study with an average age of 12.4 years ± 7.9. The overall prevalence of caries measured with the DMF index was 58.6% 95% CI [51.2 - 65.8]. It was significantly associated with female gender (OR = 4.2;95% CI [1.4 - 12.5], p = 0,01), the clinical form of mental illness (epilepsy OR = 3.8 95%;CI [1.2 - 12.7], p = 0,02, trisomy OR = 5.0;95% CI [1.1 - 22.9], p = 0,03, motor autonomy OR = 0.2 95%;CI [0.1 - 0.7], p = 0,01) and at use of toothpaste OR = 9.33;95% CI [1.05 - 82.7], p = 0,04. Conclusion: Dental caries remains a very present pathology in most people living with an intellectual disability. Also, it is necessary to put in place prevention strategies to reduce its prevalence and improve access to oral care for these people.

Angiosarcoma of the scalp diagnosed by the presence of neck inflammation:a case report

引用

International Journal of oral Science 2012年第3期4卷 166-169页

作者： Rei Karube Hiroyoshi Sasaki Keiji Shinozuka Yasuhiro Fujisawa Toru Yanagawa Kenji Yamagata Kojiro Onizawa Fujio Otsuka Hiroki Bukawa department of oral and maxillofacial surgery Faculty of MedicineUniversity of Tsukuba department of Dermatology Faculty of MedicineUniversity of Tsukuba

Angiosarcoma is an uncommon malignancy, which spread out from the endothelial cells of vessels. Scalp angiosarcoma with cervical lymph node metastasis is particularly rare. This article describes a rare case of angiosarcoma of the scalp, presenting as neck inflammation. Imaging procedures such as computed tomography （CT）, magnetic resonance image （MRI） and ultrasonography （US） were not sufficient to diagnose this case. A needle biopsy provided an effective and accurate diagnosis of cervical lymph node metastasis. Additional observation and physical examination was required to diagnose the origin of the primary cancerous lesion. Once the angiosarcoma diagnosis was confirmed histologically, sequential weekly and monthly docetaxel （DTX） treatment was effective in preventing reoccurrence. Nonetheless, the optimization of angiosarcoma treatment remains a future goal. Although patients generally describe pain and swelling at the primary lesion site, this patient complained only of painful neck inflammation, without any indication of pain or swelling of the scalp. A revised diagnostic protocol should note that cervical lymph node metastasis of unknown primary origin may result from angiosarcoma of the scalp.
