Primary syphilis of the rectum--endoscopic and clinical features. Report of a case.

A 33-year-old man was admitted to our hospital for suspected rectal tumor. Endoscopy showed a rectal mass not typical of carcinoma, and histologic evaluation of biopsy specimens revealed granulomatous inflammation. Venereal Disease Research Laboratories (VDRL) and Treponema pallidum hemagglutination (TPHA) tests became positive during hospitalization, and dark-field examination was positive for Treponemas, thus allowing the diagnosis of chancre of the rectum. The clinical and endoscopic features of this case are described.

Confrontation de l'échographie bidimensionnelle à la scanographie et à la scintigraphie aux plaquettes marquées à l'indium 111.

Three methods of diagnostic imaging : bi-dimensional ultrasonography, scanography and 111Indium-labelled platelet scintigraphy were compared in 61 patients to detect left intraventricular thrombotic lesions, in order to determine their respective diagnostic values.
