RESUMO
Tubulovillous adenomas of the duodenal ampulla are rare neoplasms. The present report describes a case with radiological-endoscopic and pathological correlation in which the patient underwent duodenal pancreatectomy with good postoperative progression. With advanced imaging methods, especially magnetic resonance and endoscopic ultrasound, locoregional aspects and extraluminal, lymphovascular, and metastatic invasion have been increasingly discussed as contributors to therapeutic decision making. This progression improves lesion staging and is especially useful in selecting eligible candidates for endoscopic treatment.

RESUMO Os adenomas túbulo-vilosos da ampola duodenal são neoplasias raras. Neste trabalho apresentamos um caso com correlação radiológico-endoscópica e patológica, tendo a paciente sido submetida à duodenopancreatectomia com boa evolução pós-operatória. Com os avanços dos métodos de imagem, em especial da ressonância magnética e ultrassonografia endoscópica, aspectos locorregionais, além da invasão extraluminal, linfovascular e metastática, têm sido discutidos de maneira crescente como contribuintes na decisão terapêutica. Essa evolução contribui para o melhor estadiamento destas lesões e é especialmente útil para selecionar candidatos elegíveis ao tratamento endoscópico.

CONTEXT: The presence of multiple neoplasms in one patient is an uncommon event. Its occurrence ranges from 1.2% to 4.5% of cancer patients in autopsy and clinical studies. In the present article, cases of synchronous diagnoses of carcinoma and lymphoid neoplasms are reported. The intention of this report was to alert clinicians and pathologists to the possibility of the existence of concomitant neoplasms, in order to prevent inaccurate or delayed diagnosis and staging. CASES: Seven patients (four female and three male) with a median age of 61.4 years were diagnosed as having concomitant epithelial and hematological neoplasms. DISCUSSION AND CONCLUSION: Lymph nodes should be carefully examined when searching for metastases, because of the possibility of a second hematological malignancy. Whenever uncommon suspicious morphological features are seen in such neoplasms, an immunohistochemical analysis is essential.

CONTEXTO: A presença de múltiplas neoplasias em um mesmo paciente é evento infreqüente, correspondendo a 1,2 por cento-4,5 por cento dos pacientes com câncer em estudos clínicos e de autópsias. Neste artigo, os autores relatam casos de diagnósticos sincrônicos de carcinomas e neoplasias linfóides. Ao apresentar estes casos, tenciona-se alertar clínicos e patologistas para a possibilidade da ocorrência de neoplasias concomitantes, para evitar atrasos ou erros diagnósticos ou de estadiamento da doença. SÉRIE DE CASOS:Sete pacientes, quatro mulheres e três homens, com média de idade de 61,4 anos, foram diagnosticados com neoplasias epitelial e hematológica concomitantes. DISCUSSÃO E CONCLUSÃO: Os linfonodos devem ser cuidadosamente examinados quando se buscam metástases, dada a possibilidade de uma neoplasia hematológica concomitante. Sempre que aspectos morfológicos suspeitos forem detectados, um estudo imunoistoquímico faz-se necessário.
