Pseudomonas orchitis in puberty.

Acute epididymo-orchitis is a common cause of 'acute scrotum' in adolescence and young adults, and the common causative pathogens are Chlamydia trachomatis and Neisseria gonorrhoeae. This is a rare case of acute epididymo-orchitis due to Pseudomonas aeruginosa in a pubertal boy with a history of 'ano-receptive' intercourse. On Medline search there are no reports of pseudomonas orchitis in this age group.
