Balanitis Xerotica Obliterans (BXO) is a variation of lichen sclerosus et atrophicus, which is common in middle-aged men and is a painful condition associated with patches of white, thinned skin. Uncircumcised and diabetic males have an increased risk, and the patient with longstanding BXO has a higher risk for squamous cell carcinoma of the penis.
Answer to Question 2
ANS: D
The inflammation of the epididymis is caused by the spread of an infection from the bladder or urethra, owing to an alteration in the urethral closure mechanism. In heterosexual men younger than 35, the causative organisms are likely to be Neisseria gonorrhoeae and Chlamydia trachomatis. In homosexual men, the causative organism is usually Escherichia coli. In cases in which an organism associated with a sexually transmitted disease (STD) is suspected, the exposure to the organism can significantly predate the development of epididymitis.
