RESUMO
A biópsia de fragmentos é uma importante opção para a abordagem das lesões palpáveis e não palpáveis da mama. O objetivo deste estudo é comparar os achados histológicos da biópsia de fragmentos com os da biópsia excisional. Foram comparados os resultados de 267 biópsias de fragmentos com os da biópsia excisional de lesões palpáveis e não palpáveis da mama, realizadas no Serviço de Mastologia dos Hospitais Luxemburgo e Mário Penna. A concordância entre a biópsia de fragmentos e a biópsia excisional foi de 96,6%. A incidência de lesões benignas foi de 52,4%, com achado de lesões malignas em 46,7% dos casos. A sensibilidade foi de 96,2 % e a especificidade, 98,7%, com valores preditivos positivo e negativo de 96,6 % e 98,5%, respectivamente. Os resultados deste estudo são compatíveis com aqueles da literatura mundial e confirmam que a biópsia de fragmentos é uma excelente opção no diagnóstico das lesões da mama, com a vantagem de ser um procedimento menos custoso e poder evitar um grande número de cirurgias.
Core-biopsy is an important option to approach palpable and non-palpable breast lesions. The objective of this study is to compare the histological findings of core-biopsy and excisional biopsy. A total of 267 core-biopsies were compared to the excisional biopsies of palpable and non-palpable lesions of the breast, performed at Mário Penna and Luxemburgo Hospital's Breast Department. The concordance between core-biopsy and surgical biopsy was 96,6%. The incidence of benign disorders was 52,4% with finding of malignant lesions in 46,7% of the cases. The sensibility was 96,2% and the specificity was 98,7%, with positive predictive value and negative predictive value 96,6 and 98,5%, respectively. The results of this study are compatible with those of the world literature and confirm that core-biopsy is an excellent option for the diagnosis of breast lesions, with the advantage of being a less expensive procedure that can avoid a large number of surgeries.

The lymphangioma is a rare disease, more frequently reported in children and just occasionally in the adult patient. The lymphangioma is considered a benign neoplasm of embryonic origin of the lymphatic vessels. Its habitual location is in the cervical and axillary area; it is rarely found in the abdominal cavity and exceptionally in the retroperitonio. In this latter location, the lesion habitually is asymptomatic. The clinical diagnosis of the retroperitoneal cystic lymphangioma is not often due to its rarity and the absence of clinical expression. The size of the lesion is more important than its location to the symptomatology development. The findings of the abdominal ultrasonography and computerized tomography of the abdomen usually show a cystic lesion and its location. The treatment is surgical and it consists of the resection of the cyst or group of cysts once the liquid accumulation in its interior may be responsible for the development of some important complications of this disease. The cure is obtained when the lesion is completely resected also with the resection of eventual adhesive structures. The relapse may take place when the resection is incomplete. A case of retroperitoneal lymphangioma in a female adult patient as incidental finding of abdominal ultra-sonography is described. It is discussed the clinical picture, the radiologic diagnosis, the treatment and the prognostic of this unusual disease.
