Warthin's tumor of the parotid gland: study of 70 cases.

OBJECTIVE: To report the clinical characteristics, treatment and complication of Warthin tumors. METHODS: we conducted a retrospective study of 70 patients undergoing resection of papillary lymphomatous cystadenoma. VARIABLES: age, sex, ethnicity, presence or absence of smoking, primary site of tumor, tumor size in cm, presence of bilateral tumor, type of operation, multicentricity, treatment complications, recurrence and follow up. RESULTS: Forty-four patients (62.8%) were male and 26 (37.2%) female, with a mean age of 56.7; smoking was present in 55 (78.6%) patients; 66 (94.3%) tumors were unilateral and four (5.7%) bilateral, with an average size of 4.1 cm on physical examination. The complications were 14 (19%) cases of facial paresis and / or paralysis, seroma in 10 (13.8%), Frey's syndrome in three (4%), hematoma in two (2.7%) and wound infection in one (1.5%) case. CONCLUSIONS: Warthin tumors have a higher incidence in male smokers and predominantly unilateral location of the parotid gland. Superficial parotidectomy with preservation of facial nerve was effective in 100% cases. Complications were transient paresis or paralysis, seroma, Frey syndrome, hematoma and wound infection.

[Neck skin collision tumor]. / Tumor de colisão de pele do pescoço.

The collision or mixed tumor is a malignant neoplasm of the skin related to sun exposure and incidence rates of up to 1.5%. It displays a distinctive clinical behavior in relation to other malignancies of the skin and the histological diagnosis, characterized by the collision between a basal cell carcinoma and squamous cell carcinoma, i.e., two malignancies with distinct histologies and sharp interface between them. The case reported was of a male, 73-year-old patient, with two cervical lesions progressively growing in recent months. The chosen treatment was surgery. Histological examination showed the presence of squamous cell carcinoma adjacent to basal cell carcinoma. These tumors preferentially occur in light-skinned men in the fifth or sixth decades of life. Their most common location is in the head and neck, especially in the central part of the face. The differential diagnosis of basal-squamous carcinoma is defined by distinct histological criteria, since both tumors have similar clinical behavior. Local recurrence rates vary from 12% to 45%, whereas regional ones are of approximately 7.5%. The main prognostic factors are gender, surgical margins, perineural infiltration and lymph node status. The treatment of choice is resection, radiotherapy being indicated as adjuvant or to inoperable lesions. Local recurrence is the main limiting factor in disease-free survival, with poor results.

Tumor de Warthin da glândula parótida: estudo de 70 casos / Warthin's tumor of the parotid gland: study of 70 cases

OBJETIVO: Relatar as características clínicas, tratamento e complicações.dos tumores de Warthin. MÉTODOS: Estudo retrospectivo com 70 pacientes submetidos à ressecção de cistoadenoma papilífero linfomatoso,. Variáveis analisadas: idade, sexo, etnia, presença ou não de tabagismo, sítio primário do tumor, tamanho do tumor em centímetros, presença de bilateralidade, tipo de operação, multicentricidade, complicações do tratamento, presença de recidiva no seguimento e tempo de seguimento.. RESULTADOS: Quarenta e quatro pacientes (62,8 por cento) eram do sexo masculino e 26 (37,2 por cento), do sexo feminino, com média etária de 56,7 anos, O tabagismo estava presente em 55 (78,6 por cento) pacientes, (94,3 por cento) dos tumores eram unilaterais e quatro (5,7 por cento) bilaterais, com tamanho médio de 4,1cm ao exame físico. As complicações foram 14 (19 por cento) casos de paresia e/ou paralisia facial, seroma em 10 (13,8 por cento), síndrome de Frey em três (4 por cento), hematoma em dois (2,7 por cento) e infecção de ferida operatória em um (1,5 por cento) caso. CONCLUSÃO: O tumor de Warthin tem maior incidência no sexo masculino, em tabagistas e localização unilateral predominante na glândula parótida. A parotidectomia superficial com preservação do nervo facial mostrou-se eficaz em 100 por cento casos. As complicações encontradas foram paresias ou paralisias transitórias, seroma, síndrome de Frey, hematoma e infecção de ferida operatória.

Tumor de colisão de pele do pescoço / Neck skin collision tumor

O tumor de colisão ou tumor misto é uma neoplasia maligna de pele, relacionada à exposição solar e com índices de incidência de até 1,5 por cento. Apresenta comportamento clínico peculiar, em relação às demais neoplasias malignas de pele e com diagnóstico histológico, caracterizado pela colisão entre um carcinoma basocelular e um carcinoma epidermóide, ou seja, duas neoplasias com histologias distintas e interface nítida entre ambas. O caso relatado foi de paciente do sexo masculino, 73 anos, com duas lesões cervicais de crescimento progressivo nos últimos meses. O tratamento realizado foi cirúrgico, com exame histológico demonstrando a presença de carcinoma de células escamosas contíguo ao carcinoma de células basais. O acometimento preferencial ocorre em homens de pele clara, na quinta ou sexta décadas de vida. Sua localização mais comum é na cabeça e pescoço, principalmente na parte central da face. O carcinoma basoescamoso é diagnóstico diferencial, definido através de critérios histológicos distintos, uma vez que ambas neoplasias apresentam comportamento clínico semelhante. Os índices de recidiva local variam de 12 por cento a 45 por cento, enquanto que é baixo na recidiva regional, de aproximadamente 7,5 por cento. Os principais fatores prognósticos são o gênero do paciente, margens cirúrgicas, infiltração perineural e status linfonodal. O tratamento de escolha é a ressecção, sendo a radioterapia indicada na sua adjuvância e lesões irressecáveis. A recidiva local é o principal fator limitante na sobrevida livre de doença que apresenta resultados pobres.
