RESUMO Este artigo ilustra um caso de angiossarcoma primário cardíaco acompanhado de uma revisão dessa rara neoplasia. Relatamos o caso de um paciente do sexo masculino, 44 anos, com suspeita de mixoma em átrio direito. O tumor, ao exame anatomopatológico, mostrou tratar-se de um angiossarcoma cardíaco. No pós-operatório, o paciente cursou com tamponamento cardíaco, necessitando ser reoperado e evoluindo a óbito. Angiossarcomas são tumores malignos caracterizados por curso clínico devastador. Apresentam predileção pelo átrio direito, e ocorrem entre a terceira e a quinta década de vida, com preponderância no sexo masculino. Devido a sua raridade, o tratamento ideal ainda não está bem estabelecido.

ABSTRACT This article reports a case of primary cardiac angiosarcoma and a brief review is provided. A 44-year-old male patient was suspected of having myxoma in the right atrium. The tumor, on pathology examination, was shown to be a cardiac angiosarcoma. In the postoperative period, the patient developed a cardiac tamponade, requiring reoperation and evolving to death. Angiosarcomas are malignant tumors characterized by a devastating clinical course. They have a predilection for the right atrium, occurring between the third and fifth decades of life, with a male preponderance. Because of its rarity, the ideal treatment has not been identified yet.

INTRODUCTION: Gleason score, which has a high interobserver variability, is used to classify prostate cancer. The most recent consensus valued the tertiary Gleason pattern and recommended its use in the final score of needle biopsies (modified Gleason score). This pattern is considered to be of high prognostic value in surgical specimens. This study emphasized the evaluation of the modified score agreement in needle biopsies and in surgical specimen, as well as the interobserver variability of this score MATERIALS AND METHODS: Three pathologists evaluated the slides of needle biopsies and surgical specimens of 110 patients, reporting primary, secondary and tertiary Gleason patterns and after that, traditional and modified Gleason scores were calculated. Kappa test (K) assessed the interobserver agreement and the agreement between the traditional and modified scores of the biopsy and of the surgical specimen RESULTS: Interobserver agreement in the biopsy was K = 0.36 and K = 0.35, and in the surgical specimen it was K = 0.46 and K = 0.36, for the traditional and modified scores, respectively. The tertiary Gleason grade was found in 8%, 0% and 2% of the biopsies and in 8%, 0% and 13% of the surgical specimens, according to observers 1, 2 and 3, respectively. When evaluating the agreement of the traditional and modified Gleason scores in needle biopsy with both scores of the surgical specimen, a similar agreement was found through Kappa CONCLUSION: Contrary to what was expected, the modified Gleason score was not superior in the agreement between the biopsy score and the specimen, or in interobserver reproducibility, in this study.
