Prostatic chondroma.

The presence of cartilage in the prostate is a rare occurrence and has been reported to be the result of extension from a chondrosarcoma, usually of the symphysis pubis. Also reported has been the occurrence of cartilaginous metaplasia within the prostate. We report herein the occurrence of cartilaginous tissue within the prostate forming a distinct mass of chondroma. To our knowledge this has not been reported previously.

Endocarditis caused by Actinobacillus actinomycetemcomitans.

Actinobacillus actinomycetemcomitans is a gram-negative coccobacillus which is a very rare cause of bacterial endocarditis. Preexisting cardiac lesions are a main contributing factor, and antibiotic prophylaxis has long been felt necessary before dental or other manipulation to prevent endocarditis. Penicillin in combination with an aminoglycoside has been the most often used treatment regimen. We present a case of endocarditis caused by this organism which developed after antibiotic prophylaxis for dental cleaning. Streptomycin and rifampin therapy resulted in the cure of the infection. The treatment and epidemiology of Actinobacillus endocarditis are reviewed.

Fryns syndrome: a new variable multiple congenital anomaly (MCA) syndrome.

We report a brother and sister who died neonatally with a distinctive but variable multiple congenital anomaly (MCA) syndrome. Anomalies in both included similar facial changes, cleft palate, distal digital hypoplasia, lung hypoplasia, and urogenital abnormalities. They were discordant for cleft lip, diaphragmatic hernia, and Dandy-Walker anomaly. These sibs resemble three recently reported stillborn children and support the existence of a "new" autosomal recessive MCA syndrome with variable expressivity.
