Incidence and profile of benign epithelial tumors of salivary glands from a single center in Northeast of Brazil

2020

Background Benign tumors of the salivary glands are a group of lesions with varied histopathological and clinical spectrum. The aim was to determine the incidence and clinicopathological characteristics of benign salivary gland neoplasms diagnosed between 2007 and 2016 in a single center located in northeastern Brazil. Material and Methods Records regarding sex, age, anatomical location, histopathological subtype and treatment were retrieved, and data were analyzed using the Stata/IC software (version 12.0). Results There were above 7,100 cases of neoplasms in the head and neck region, of which 403 corresponded to salivary gland neoplasms. Of these, 238 (59%) were benign, being pleomorphic …

Perineal Excision of a Large Angiomyxoma in a Young Woman Following Magnetic Resonance and Angiographic Imaging

2001

Abstract Background. Aggressive angiomyxomas are rare, arise from connective tissue of the perineum or the lower pelvis, and affect predominantly young women. Case. We describe an unusual case of aggressive angiomyxoma in which the perineal approach was possible owing to MRI scanning and selective angiography indications. Conclusion. In cases of large aggressive angiomyxomas these diagnostic procedures should make it possible to decide which operative route might be best for the patient.

Large-sized pleomorphic adenoma of the cheek treated with Nd:Yag laser: Report of a case and review of the literature

2020

Pleomorphic adenoma (PA) mostly involves parotid glands, while extra-parotid localizations are relatively uncommon. Particularly, PAs of the cheek minor salivary glands with a size larger than 4 cm are exceedingly rare, with only few cases reported. Surgical treatment of PA usually consists in radical excision. However, despite a presumptive radicality, recurrences, sometimes followed by malignant transformation, may occur. Here we report a case of a large-sized (6 cm) PA of the cheek minor salivary glands in a 70 year-old female patient, successfully treated through a conservative approach, based on the use of Nd:YAG Laser (λ=1064 nm). No recurrences were observed after a 2-year follow-up.…

Surgical management of pleomorphic adenoma of parotid gland in elderly patients: Role of morphological features

2014

AbstractThe neoplasms of the salivary glands account for 2% of head and neck tumors and the most common form is the Pleomorphic adenoma (PA). Parotid gland is affected from 80% to 90% of cases. In elderly these tumors occur mostly in females. These benign tumors are composed of epithelial and myoepithelial cells that are arranged with various morphological patterns and subtypes. The classification of these tumors is also based on the amount and nature of the stroma. In literature there is an almost complete consensus that, in the major salivary glands, PAs are enclosed by a layer of fibrous tissue often called “capsule” but there is disagreement about the form, extension and thickness of th…

Epidemiologic analysis of salivary gland tumors over a 10-years period diagnosed in a northeast Brazilian population

2020

Background Salivary gland tumors (SGT) correspond to a heterogeneous group of lesions with variable biological behavior. The present study aimed to determine the distribution and demographic findings of salivary gland neoplasms in a northeast Brazilian population. Material and Methods A retrospective descriptive cross-sectional study was performed. A total of 588 cases of SGT were diagnosed between 2006 and 2016 of 4 pathology services in the state of Sergipe, Brazil. All cases were reviewed, and data such as sex, age, anatomical location, and histopathological diagnosis were collected. Results A total of 470 (79.9%) tumors were benign and 118 (20.1%) were malignant. The majority of the pat…

Incidence and prevalence of salivary gland tumours in Valparaiso, Chile

2014

Background : To determine the incidence and prevalence of salivary gland tumours in the province of Valparaíso, Chile. Material and Methods : Retrospective review of salivary gland tumours diagnosed between the years 2000 and 2011 from four local pathology services. Information on demographics and histopathology were retrieved from the medical records. Results : The study sample consisted of 279 salivary gland tumours. Prevalence and incidence rates per 100.000 persons were 15.4 and 2.51, respectively. Most of the neoplasms corresponded to benign tumours (70.3%). The most affected gland was the parotid gland. Pleomorphic adenoma was the most common benign tumour (53.8%) and mucoepidermoid c…

Pleomorphic adenoma of the nasal septum: A rare case report of a 14 year-old patient

2018

Pleomorphic adenoma is the most common benign tumor of the salivary glands. It arises mainly from the parotid, less frequently from the minor salivary glands of the oral cavity and, exceptionally, from the accessory glands widespread in the upper aero-digestive tract. Intranasal localization is rare and mainly affects the glands sited in the nasal septal mucosa. There are isolated case reports in literature regarding adult patients. We report a rare case of a young 14-year-old girl with pleomorphic adenoma arising from the nasal septum.

Multicentric recurrent parotid pleomorphic adenoma in a child

2009

Mixed tumours of the parotid gland are rare in childhood and recurrence of this tumour is infrequent. Some authors report a higher rate of recurrence with some histological subtypes, like hypocellular variant. Female sex and young age at initial treatment are also risk factor for recurrence. Also the first surgical treatment, tumour enucleation or parotidectomy, has been implicated as a cause for recurrence. We present a case of a multicentric doubly recurrent parotid pleomorphic adenoma, 7 and 14 years after tumour enucleation, in a 9-year-old child. All the nodules resected showed the hypocellular variant of pleomorphic adenoma. We consider the relationships between the choice of treatmen…

A review of 413 salivary gland tumours in the head and neck region.

2013

Objectives: Salivary gland tumours (SGTs) are a group of heterogeneous lesions with complex clinico-pathological characteristics and distinct biological behaviours. Previous studies have reported geographic variations in site distribution, incidence and histological types of SGTs. The aim of this study was to describe the demography of SGTs seen at a tertiary health centre and compare findings with previous studies. Study design: Data on SGTs from archives of the Department of Oral Pathology and the Department of Pathology, University College Hospital Ibadan were retrieved. Information about histological types, age, sex and location were analyzed using SPSS for Window (version 20.0; SPSS In…
