Rectal Metastases of Breast Carcinoma: A Case Report.

The scarcely reported hematogenous rectal metastases from breast cancer are rare and the diagnosis is challenging. They may be recognized before, concomitantly with, or after the diagnosis of the primary site of breast cancer.

Miliary tuberculosis: the role of necropsy studies.

This case study of generalized miliary tuberculosis in a Brazilian man without AIDS is reported in order to emphasize the role of histopathological study for diagnosis. We comment on a recent Indian study involving 40 cases of surgical and necropsy specimens in which the diagnosis of tuberculosis was made, as well as a previous Brazilian case report.

Comments on Saint's triad.

Yamanaka et al. described two case studies involving coexistent cholelithiasis, hiatal hernia, and umbilical hernias, and discussed clinical similarities with the classical features of the Saint's triad. Cholelithiasis, hiatal hernia, and colonic diverticulosis characterize the classical triad, but some authors have included any type of hernia due to herniosis-a developmental disorder of the extracellular matrix.

Weil's syndrome.

A case of leptospirosis in an 18-year-old white male was reported. Weil's syndrome was characterized by intense jaundice, acute renal failure, skin ecchymoses and conjunctival suffusion, in addition to meningitis. The polymerase chain reaction for Leptospira was negative, while the titers of the antibody microagglutination test against L.
