ABSTRACT

PURPOSE: The present study aimed to provide the clinicopathological data of Brazilian patients with basal cell adenoma (BCA). METHODS: Records of BCA cases were retrospectively gathered from the Brazilian National Cancer Institute database between 1996 and 2006. All cases were histopathologically reviewed, and the clinicopathological data were collected from the patients' medical files. In addition, an English literature review about this tumor is also presented. RESULTS: Of 1127 salivary gland tumors identified, 30 were BCAs (2.7%). Women were more affected than men (70.0% vs. 30.0%), and the majority (60.0%) were elderly (> 65 years old). The parotid gland was the most frequent location affected (93.3%), followed by the upper lip (3.3%) and submandibular gland (3.3%). Fine-needle aspiration was the main procedure applied to establish a preoperative diagnosis of tumor; however, the results were not always consistent. Histopathologically, the trabecular pattern was the most common type seen (50.0%) among our BCA samples. Most patients underwent superficial or partial parotidectomy. Frey's syndrome was reported only in one case during the follow-up. No recurrence was noted in the present series. The literature review revealed a total of 213 reported cases of BCA in the period investigated. CONCLUSIONS: This is the first case series of BCA reported in Brazil. As occurred in other previously reported series, the clinicopathological data of BCAs are similar and confirm that this type of tumor is rare, develops predominantly in the parotid gland, frequently affects older women, has an indolent behavior, and the affected patients have an excellent prognosis.

ABSTRACT

Se realizó un estudio descriptivo en 97 pacientes atendidos e intervenidos quirúrgicamente en la consulta de cirugía maxilofacial del Hospital General Docente Dr Octavio de la Concepción y de la Pedraja en el municipio Baracoa, Guantánamo, con tumores de la glándula parótidas en el período de enero de 1992 a diciembre del 2013, con el objetivo de caracterizar el comportamiento clínico-quirúrgico de tumores de esta glándula. Para este estudio se tuvo en cuenta el grupo etario, sexo y color de la piel, localización anatómica; el procedimiento quirúrgico y las principales secuelas postoperatorias. Entre los resultados principales resaltó el predominio del grupo etario de 21-40 y el sexo masculino fue el más afectado, así como el color mestizo. Estuvo más afectada la glándula parótida derecha, la mayoría de los casos se abordaron con la incisión de S de Blair y la localización del nervio facial con el método directo o troncular(AU)


It was carried out a descriptive study of the 97 patients assisted in the consultation of maxillofacial surgery of the Educational General Hospital Dr. Octavio de la Concepción y de la Pedraja, with tumors of the parotid gland in the period of January 1992 to December 2013, with the objective of knowing the clinical-surgical behavior of the treated affections. In this study it was taken into considerations according to the age, sex, color of the skin, anatomical localization; also, it was described the surgical procedure and the main postoperative sequels. Among the main results highlighted the predominance of the age group of 21-40 and the male sex was the most affected, as well as the mestizo color. The right parotid gland was more affected, the majority of cases were approached with Blair's S incision and the location of the facial nerve with the direct or truncal method(AU)

ABSTRACT

BACKGROUND: Prior epidemiological studies had examined the association between cell phone use and the development of tumors in the parotid glands. However, there is no consensus about the question of whether cell phone use is associated with increased risk of tumors in the parotid glands. We performed a meta-analysis to evaluate the existing literature about the mean question and to determine their statistical significance. METHODS: Primary association studies. Papers that associated cell phone use and parotid gland tumors development were included, with no restrictions regarding publication date, language, and place of publication. Systematic literature search using PubMed, SciELO and Embase followed by meta-analysis. RESULTS AND CONCLUSION: Initial screening included 37 articles, and three were included in meta-analysis. Using three independent samples including 5087 subjects from retrospective case-control studies, cell phone use seems to be associated with greater odds (1.28, 95%- confidence interval: 1.09-1.51) to develop salivary gland tumor. Results should be read with caution due to the limited number of studies available and their retrospective design.

ABSTRACT

Los tumores de glándulas salivales son poco frecuentes y presentan características microscópicas complejas. Estos comprenden menos del 3 por ciento de todas las neoplasias de la región de cabeza y cuello. Se reportan en la literatura distintas incidencias en los tumores de glándulas salivales. El presente estudio fue llevado a cabo en el Servidio de Cirugía Maxilofacial, con conjunto con el Servicio de Anatomía Patológica del Hospital Zonal Mariano y Luciano de la Vega, Moreno, Buenos Aires, Argentina. El objetivo del mismo fue conocer la incidencia de los tumores, distinción por sexo y edad de los pacientes. Se analizaron 78 casos de tumores en glándulas salivales mayores (parótida, submaxilar y sublingual) y glándulas salivales menores. La mayor frecuencia de aparición la encontramos en glándulas salivales menores (46.2) 36 pacientes, seguido por la localización en gla´dnula salival (37, 1) 29 pacientes y luego en glándula submaxilar (16, 7) 13 pacientes. El adenoma pleomorfo fue el tumor más frecuentemente hallado, representando 55.1 por ciento de todos los casos, seguido por el tumor de Whartin, 12,8 por ciento y el carcinoma mucoepidermoide 8,9 por ciento.

ABSTRACT

OBJECTIVE: The aim of this study was to determine the distribution and demographic features of salivary gland tumors (SGTs) in a large Brazilian population. STUDY DESIGN: A total of 493 cases of SGTs diagnosed between 2001 and 2011 from a general pathology laboratory and an oral pathology service were reviewed with respect to their clinicopathologic features. RESULTS: A total of 369 tumors were benign and 124 were malignant. The mean age of patients with benign tumors was 46.3 years and that of patients with malignancies was 54.0 years. The parotid gland was the most common location (42.3%). Pleomorphic adenoma (PA) and Warthin's tumor were the most common benign neoplasias, whereas mucoepidermoid carcinoma (MEC) and adenocarcinoma, not otherwise specified, were the most frequent malignancies. CONCLUSIONS: The present data confirm that PA and MEC are the most common benign and malignant SGTs. However, it is important to consider that differences in tumor types may be influenced by whether a tumor derives from a medical or a dental service.

Objetivo: se presenta una investigación epidemiológica sobre la incidencia de tumores benignos y malignos de glándulas salivales mayores en el Hospital Central de San Luis Potosí del periodo comprendido de 1996 a 2006. Material y metodos: Los datos fueron obtenidos de los reportes histopatológicos y expedientes clínicos. Los diagnósticos se basaron en la clasificación de tumores de glándulas salivales de la OMS. Resultados: Los casos se dividieron en dos grupos: epiteliales y no epiteliales. El grupo I correspondió al 87 por ciento los tumores benignos fueron más frecuentes (56 por ciento). El 54 por ciento de los tumores se presentaron en mujeres. La época de vida predominante fue la 2da década en los tumores benignos y la 6da en los malignos. La localización más común fue la glándula parótida con 88 por ciento de los tumores benignos y 65 por ciento de los malignos. El adenoma pleomorfo fue el tumor más frecuente (51 por ciento) seguido del Ca. mucoepidermoide (17 por ciento). El 88 por ciento de los casos no presentaron complicaciones postoperatorias; la más frecuente fue la lesión del nervio facial (7 por ciento) en los tumores malignos. El grupo II correspondió al 13 por ciento de los casos, predominando en la parótida (56 por ciento) y siendo más frecuente el hemangioma.

ABSTRACT

PURPOSE OF THE STUDY: To report the largest Brazilian series of Warthin's tumor (WT). PROCEDURES: The medical files of 76 patients with WT treated in the Brazilian National Cancer Institute from 1996 to 2006 were reviewed. RESULTS: The male:female ratio was 2:1, with a predominance of white, old, and smoking patients. However, there were more women among the nonsmokers. One fifth of the patients presented with synchronous multiple lesions. Parotid lesions were prevalent, but there were patients with lesions in cervical lymph nodes and in the inferior lip. Most cases were treated by superficial parotidectomy, without recurrences. One fourth of the patients also developed other primary neoplasms. CONCLUSIONS: The observed data do not differ from those in the international literature. Multiplicity and the development of other neoplastic diseases require close clinical management of patients with WT. MESSAGE: The previously unreported observation of female prevalence among nonsmoking people with WT should be confirmed and explored in future studies.

ABSTRACT

Objetivo: estudiar la efectividad de los extendidos y fragmentos obtenidos a través de la PAAF en glándulas salivales mayores. Se realizó una revisión de la literatura sobre PAAF y estudio de fragmentos titulares en glándulas salivales. Se punzaron 21 masas en glándulas salivales mayores y los resultados fueron comparados con el estudio anatomopatológico de la pieza quirúrgica en caso de que estuviera indicado. Se realizaron 21 PAAF y se obtuvo 15 extendidos satisfactorios (71 por ciento). El resultado de las PAAF sugirió la presencia de 9 tumores benignos, tres lesiones infecciosas, una lesión linfoproliferativa y 2 metástasis. Fue posible tomar fragmentos con la PAAF en 5 casos y en4 fueron efectivos en el diagnóstico. Se evitó realizar cirugías innecesarias en 4 casos (26 por ciento). El uso combinado de extendidos citológicos y fragmentos obtenidos por PAAF es una alternativa valiosa para el diagnóstico preoperatorio de lesiones que afectan glándulas salivales mayores; de todas maneras hacen falta más estudios sobre el uso combinado de ellos

ABSTRACT

Salivary gland tumors are uncommon and the microscopical features can be complex. Epidemiological data of these tumors in the various parts of the world can be helpful for a better understanding of its biology and clinical characteristics. In this study, 496 epithelial and mesenchymal tumors of major and minor salivary glands diagnosed at Londrina Cancer Institute during the period from 1972 to 2001 were reviewed. Out of all cases, 335 (67.5%) were classified as benign and 161 (32.5%) as malignant. The majority of the cases occurred in the parotid gland (67.7%), followed by the minor salivary glands (22.8%) and submandibular gland (9.5%). Among the minor salivary gland tumors, the palate was the most frequent location (67%). The tumors affected more commonly adult patients with peak incidence between 40 and 50 years of age and with a slightly predominance in females. Pleomorphic adenoma was the most frequent tumor representing 54.2% of all cases, followed by mucoepidermoid carcinoma (13.5%), Warthin's tumor (8.5%) and adenoid cystic carcinoma (7.9%).

ABSTRACT

Antecedentes: muchos autores han descripto diferentes algoritmos de estudio y tratamiento para el adenoma pleomorfo de la glándula parótida. Objetivo: analizar la clínica, el algoritmo de estudio y evolución posoperatoria de pacientes con adenoma pleomorfo de glándula parótida y proponer la parotidectomía total como su tratamiento a elección. Lugar de aplicación: Servicio de Cirugía del H.I.G.A. Gral. San Martín de La Plata. Diseño: estudio realizado sobre una serie de 53 casos. Población: se incluyeron todos los pacientes con adenoma pleomorfo de la glándula parótida tratados en nuestro Servicio. Métodos: a todos se les realizó ecografía y P.A.A.F. La TAC únicamente a pacientes con dudas diagnósticas. En todos los casos se realizó parotidectomía total. Resultados: los 53 casos cursaron un posoperatorio sin complicaciones graves; solo un paciente presentó una recidiva a los 3 años de intervenido. Conclusiones: la parotidectomía total no presentó complicaciones posoperatorias graves y disminuyó la probabilidad de recidiva, con lo que constituyó el tratamiento de elección para el adenoma pleomorfo de la glándula parótida

ABSTRACT

OBJECTIVE: The retrospective analysis of the surgical procedures in primary parotid and metastatic or adjacent parotid tumors. PATIENTS AND METHODS: Retrospective review of the records of 145 patients operated on for primary, metastatic or adjacent parotid tumors revealed 85 patients with benign tumors, 24 with primary malignant tumors, 19 with squamous skin carcinomas, 12 with skin melanomas, 3 with basocellular carcinomas and 2 with sarcomas of the parotid region. The analysis included the type of parotidectomy, the need for facial nerve sacrifice (FNS), type of neck dissection and soft part reconstruction. RESULTS: Superficial parotidectomy was performed in 81% of the benign parotid tumors and 100% of skin melanomas. Total parotidectomy was frequent in malignant parotid tumors (62%), epidermoid skin tumors (64%) and in basocellular/sarcomas of the parotid region (80%). Skin graft or flaps was infrequent in primary malignant tumors (12.5%), and frequent in epidermoid skin tumors (74%), melanomas (58%) and basocellular/sarcomas (100%). FNS was necessary in primary malignant (25%), adjacent epidermoid (37%), melanomas (17%) and basocellular/sarcomas (80%). Details on neck dissections are provided. CONCLUSIONS: Superficial parotidectomy was an adequate procedure for most benign parotid tumors and for melanoma patients. In primary malignant and adjacent or metastatic skin tumors, total parotidectomy, neck dissection and soft part reconstruction were frequent procedures. FNS and soft part reconstruction should be anticipated more frequently in squamous/basocellular skin tumors or sarcomas adjacent to the parotid gland.

ABSTRACT

Entre junio de 1978 y junio de 1991 fueron evaluados 194 pacientes portadores de tumores de la glándula parótida; de ellos 42 (21,6 por ciento) fueron malignos. La mayor incidencia se registró en la sexta y séptima décadas de la vida. El tumor fue la forma de presentación más frecuente. El método de diagnóstico más efectivo, fue el estudio histológico intraoperario, mediante el cual se pudo cuantificar la magnitud de la resección. La operación mínima fue la parotidectomía total con conservación del facial (17 de 42, 40,4 por ciento). En los casos avanzados con parálisis facial, metástasis cervicales o infiltración de tejidos blandos superficiales o profundos, se realizó operación comando con algún método de reconstitución. (19 de 42, 45,2 por ciento). Las curvas analizadas por el método actuarial confirman que el tamaño del tumor, las metástasis cervicales y el tipo histológico, fueron los que incidieron negativamente en la evolución de los enfermos

ABSTRACT

En este estudio retrospectivo de los tumores de la glándula parótida se incluye a 14 pacientes vistos y tratados en el Servicio de Cirugía Oncológica del Hospital Regional "Lic. Adolfo López Mateos", en los cuales se efectuaron 15 procedimientos quirúrgicos (10 parotidectomías superficiales y tres parotidectomías totales, por procesos benignos; y dos disecciones radicales de cuello por procesos malignos, uno de ellos tratado con radioterapia coadyuvante). La mayor frecuencia de presentación, en cuento a tipo histológico se refiere, corresponde al adenoma pleomórfico (40 porciento), a la enfermedad de Mickulicz y a los tumores de Warthin (13.3 porciento cada uno, respectivamente), así como a la parotiditis crónica difusa. Las complicaciones se presentaron en bajo porcentaje y a los dos años de sobrevida de una paciente con proceso maligno no hay evidencia de actividad tumoral; ni en el resto de los casos evidencia de recurrencia. Tampoco se reportan cifras de mortalidad.

ABSTRACT

The case of a mixed tumor of the parotid gland in an 8-year-old girl is reported. The low frequency of this neoplasm in children is the reason why we show this new case. A short survey of the literature is made, with a special reference to the incidence in childhood.

ABSTRACT

Warthin's tumour has traditionally had a strong male association, and has been said to be rare in Blacks. Current studies describe a new trend; a rise in females, strongly linked to cigarette smoking. The tumour has eosinophilic epithelial cells packed with distinctive mitochondria, and a lymphoid stroma. Immunological investigations have demonstrated polyclonal B cells, T cells and macrophages. Views differ as to whether B or T cells predominate. Between 1958 and 1989, the Jamaica Cancer Registry recorded 491 benign and malignant salivary gland tumours. There were 18 cases of Warthin's tumour (3.7%), with a male: female ratio of 5:1. The low proportion of females is similar to the trend for female lung cancer in Kingston & St. Andrew. A case of Warthin's tumour was studied by light and electron microscopy and immunoenzyme methods. The epithelial cells contained numerous mitochondria with stacked cristae, as previously described. Similar morphology occurs in oncocytic tumours; riboflavin-deficient rats and mice; rats given non-lethal doses of hypoglycin; dogs treated with annatto extracts; and hibernating or starving frogs. The mitochondrial changes may be an adaptive response. The immunoenzyme studies utilized newly available monoclonal antibodies: UCHL1, L26, 4KB5, MT1 and LN2. The reaction patterns indicate a distribution of B and T cells in a manner expected in a lymph node. The interaction between mitochondrial changes, adaptive metabolic pathways, the immune cells and tobacco raises some interesting questions.

ABSTRACT

Warthin's tumour has traditionally had a strong male association, and has been said to be rare in Blacks. Current studies describe a newtrend; a rise in females, strongly linked to cigarette smoking. The tumour has eosinophilic epithelial cells packed with distinctive mitochondria, and a lymphoid stroma. Immunological investigations have demonstrated polyclonal B cells and macrophages. Views differ as to whether B or T cells predominate. Between 1958 and 1989, the Jamaica Cancer Registry recorded 491 benign and malignant salivary gland tumours. There were 18 cases of Warthin's tumour (3.7%), with a male:female ratio of 5:1. The low proportion of females is similar to the trend for female lung cancer in Kingston & St. Andrew. A case of Warthin's tumour was studied by light and electron microscopy and immunoenzyme methods. The epithelial cells contained numerous mitochondria with stacked cristae, as previously descrebed. Similar morphology occurs in oncocytic tumours; riboflavin-dificient rats and mice; rats given non-lethal doses of hypoglycin; dogs treated with annatto extracts; and hibernating or starving frogs. The mitochondrial changes may be anadaptive response. The immunoenzyme studies utilized newly available monoclonalantibodies: UCHLI, L26, 4KB5, MT1 and LN2. The reaction patterns indicate a distribution of B and T cells in a manner expected in a lymph node. The interaction between mitochondrial changes adaptive metabolic pathways, the immune cells and tobacco raises some interesting questions
