Plunging Ranula in a 78- year- old Male ? a rare case report
2018
The term Ranula is a Latin word meaning frog. It refers to a bluish translucent cystic lesion in the floor of the mouth resembling the underbelly of a frog. Ranulas can be true cysts occurring due to ductal obstruction of the sublingual gland or a minor salivary gland or a pseudocyst as a result of ductal injury leading to extravasation and accumulation of saliva in the surrounding tissues. Clinically ranulas present as intraoral or plunging ranulas. The prevalence of ranula is 0.2% per 1000 patients Ranulas account for 6% of all salivary gland cysts. Ranulas are more common in children and young adults. However the plunging type occurs most commonly in the later third decade. The diagnosis…
Dysphagie ohne klinisch erkennbares pathologisches Korrelat: Zum Ausschluss eines Tumorgeschehens des Mundbodens und des Zungengrundes ist die Ultras…
2001
In patients suffering from dysphagia, a tumour of the tongue and its base must be excluded. This is not always possible by means of endoscopy and palpation. In contrast it is possible to visualize deep-seated structures of this region by ultrasound. Unfortunately, this technique is rarely used, as shown in the cases demonstrated. We present five patients suffering from dysphagia for a long period of time (up to 30 years) where ultrasound was not performed and a tumour of the floor of the mouth and the base of the tongue was overlooked. Thus, adequate therapy was delayed, which proved to be especially relevant in three patients suffering from a malignoma. Three patients suffered from a malig…
Su Un Raro Caso di Neurofibroma Plessiforme Del Pavimento Orale
1956
A case of plexiform neurofibroma of the oral floor is described, its rarity underlined and its pathogenesis discussed. The different hypotheses concerning the tumours of the peripheral nervous system are referred and cases from the literature showing similarities with the one under examination are reviewed.
What is the frequency of floor of the mouth lesions? A descritive study of 4,016 cases.
2020
Background The aim of this study was to investigate the frequency of oral lesions in the floor of the mouth from representative oral pathology centres in Latin America. Material and Methods This study was conducted on biopsies obtained from January of 1978 to December of 2018 at nine Latin America oral and maxillofacial pathology centres. Gender, age and histopathological diagnosis were evaluated. Data were analysed using descriptive methods. Chi-square test was used for pairwise comparisons. Results From 114,893 samples, 4,016 lesions (3.49%) occurred in the floor of the mouth. Brazil showed 3,777 cases (94%), Mexico 182 cases (4.5%) and Argentina 57 cases (1.4%). Benign lesions represente…
Lymphadenomatous carcinoma of the sublingual gland: report of a first case in an unusual localization.
2008
Background. Lymphadenomatous carcinoma of the salivary gland is a very rare tumor, which hitherto occurred exclusively in the parotid gland. This report describes a case of lymphadenomatous carcinoma of the sublingual gland, which is thought to be the first report of this special entity. Methods and Results. A 36-year-old man was seen with slowly growing mass on his right floor of mouth. Upon surgical removal, the mass was well encapsulated. Microscopic exami- nation revealed a biphasic appearance with islands of neoplas- tic epithelial cells presenting against a dense lymphoid stroma, while the epithelial compartment showed features of malig- nancy. During 30-months of close follow-up, the…
Solitary fibrous tumor of the floor of the mouth
2017
Background A solitary fibrous tumor (SFT) of the oral cavity is an extremely rare entity. Its diagnosis is complicated because of its diverse morphology and similarity to other mesenchymal diseases. Case Report A rare case of SFT involving floor of the mouth is presented. The tumor was well circumscribed and almost spherical, measuring approximately 3 cm in diameter. Patient was submitted to biopsy and histopathologic examination showed a tumor composed of spindle to epithelioid cells showing pale to eosinophilic cytoplasm, oval or elongated nuclei with inconspicuous nucleoli. Tumor cells showed strong positivity for CD34, vimentin and Bcl-2. SFTs may present as a diagnostic challenge. The p…

Orofacial dermoid cysts in pediatric patients : a review of 8 cases
2010
Objective: The aim was to analyze the clinical characteristics, treatment and outcome of 8 orofacial dermoid cysts (DC) in pediatric patients. Material and Methods: A retrospective observational study was made, reviewing the medical records with clinical diagnosis of dermoid cyst between 1987 and 2006 in the Children?s Maxillofacial Surgery Department of the Hospital Universitario La Fe, Valencia, Spain. The following data were collected: sex, age, location, size and duration of the lesion, treatment, length of follow-up, and recurrence. Results: Eight patients (3 girls and 5 boys) with a mean age of 2.7 years (range 0-12 years). Four DC were located in the oral area (3 sublingual and 1 lin…
Oral cancer trends in a single head-and-neck cancer center in the Netherlands; decline in T-stage at the time of admission
2011
OBJECTIVES:In this study we evaluated the possible epidemiologic changes of oral cancer patients in the Netherlands between the years 1980-1984 and 2000-2004. We specifically studied the differences in male-female ratio, age, TNM-stage, site distribution, and alcohol and tobacco use.MATERIALS AND METHODS:Patients from the VU University Medical Center with an oral squamous cell carcinoma of the oral cavity registered in 1980-1984 (n=200), group 1, were compared to patients registered in 2000-2004 (n=184), group 2. Trends in prevalence, site distribution, TNM-stage, alcohol and tobacco use, age and gender were studied.RESULTS:The male-female ratio has decreased from 1.8 to 1.2. There were no …
